Congress and the War in Yemen: Oversight and Legislation 2015-2021

Summary
This CRS report provides an overview of the role Congress has played in shaping U.S. policy
toward the conflict in Yemen, with summary tables providing information on various legislative
proposals considered in the 114th, 115th, 116th, and 117th Congresses. These proposals have
reflected a range of congressional perspectives and priorities, including
 the authorization of the activities of the U.S. Armed Forces related to the conflict;
 the extent of U.S. logistical, material, advisory, and intelligence support for the
coalition led by Saudi Arabia;
 the approval, disapproval, or conditioning of U.S. arms sales to Saudi Arabia;
 the appropriation of funds for U.S. operations in support of the Saudi-led
coalition;
 the conduct of the Saudi-led coalition’s air campaign and its adherence to
international humanitarian law and the laws of armed conflict;
 the demand for greater humanitarian access to Yemen;
 the call for a wider government assessment of U.S. policy toward Yemen and
U.S. support to parties to the conflict;
 the nature and extent of U.S.-Saudi counterterrorism and border security
cooperation; and
 the role of Iran in supplying missile technology and other weapons to the forces
of the Houthi movement.
The 117th Congress may continue to debate U.S. support for the Saudi-led coalition and Saudi
Arabia’s conduct of the war in Yemen, where fighting has continued since March 2015. The war
has exacerbated a humanitarian crisis in Yemen that began in 2011; as of January 2022, the World
Food Programme reported that 16.2 million Yemenis were food insecure, more than half the
country’s population. The difficulty of accessing certain areas of Yemen has made it hard for
governments and aid agencies to count the war’s casualties. Data collected by the U.S. and
European-funded Armed Conflict Location & Event Data Project (ACLED) estimates that
targeted airstrikes and drone attacks reportedly killed 8,513 civilians in Yemen from March 18,
2015 to December 31, 2021, out of more than 14,573 civilians reported killed overall.
President Joseph Biden has ended some U.S. military support to Saudi Arabia and the Saudi-led
coalition and is engaged in efforts to secure a ceasefire agreement while Congress considers
proposals that could further restrict U.S. military involvement. The Biden, Trump, and Obama
Administrations have opposed various congressional proposals, including initiatives to reject or
condition proposed U.S. arms sales or to require an end to U.S. military support to coalition
operations in Yemen.

Congress and the War in Yemen: Oversight and Legislation 2015-2021

Overview
In March 2015, Saudi Arabia established a coalition of nations (hereinafter referred to as the
Saudi-led coalition or the coalition) to engage in military operations in Yemen against the Ansar
Allah/Houthi movement and loyalists of the previous president of Yemen, the late Ali Abdullah
Saleh (for background see text box below).1 During 2014, the United States joined Saudi Arabia
in demanding that Houthi forces reverse their unilateral military campaign to occupy the Yemeni
capital of Sana’a, but the rapid onset of hostilities in March 2015 forced the Obama
Administration to react quickly.2
At the start of the Saudi-led intervention on March 25, 2015, the Administration announced that
the United States would provide “logistical and intelligence support” to the coalition’s operations
without taking “direct military action in Yemen in support of this effort.”3 Soon thereafter, a joint
U.S.-Saudi planning cell was established to coordinate military and intelligence support for the
campaign, which eventually included refueling support for coalition air operations, weapons
transfers, intelligence support, and training. At the United Nations Security Council, the United
States supported the passage of Resolution 2216 (April 2015), which, among other things,
required member states to impose an arms embargo against the Houthi-Saleh forces and
demanded that the Houthis withdraw from all areas seized during the current conflict.
U.S. support for the coalition’s operations has been reduced since 2015, reflecting U.S. concerns
about civilian casualties and goals of promoting a ceasefire. After six years of conflict, hundreds
of thousands of Yemenis have been displaced, millions are in need of humanitarian assistance,
and the Houthi movement controls most of northern Yemen. Through December 2021, the
Houthis continued to launch strikes across the border into Saudi Arabia, attack areas of Yemen
loyal to the Republic of Yemen Government (ROYG), and press an offensive against the city of
Marib, seat of the last ROYG stronghold in the north.
On December 7, 2021, President Joseph Biden reported to Congress “consistent with” the War
Powers Resolution that4
A small number of United States military personnel are deployed to Yemen to conduct
operations against al-Qa'ida in the Arabian Peninsula and ISIS. The United States military
continues to work closely with the Government of the Republic of Yemen and regional
partner forces to degrade the terrorist threat posed by those groups.
As reported previously, I directed an end to the United States support for the Saudi-led
Coalition's offensive military operations against the Houthis in Yemen. United States
Armed Forces, in a non-combat role, continue to provide military advice and limited
information to regional forces for defensive and training purposes only as they relate to the
Saudi-led Coalition's campaign against the Houthis in Yemen. Such support does not
involve United States Armed Forces in hostilities with the Houthis for the purposes of the
War Powers Resolution.

Congress and the War in Yemen: Oversight and Legislation 2015-2021

United States Armed Forces are deployed to the Kingdom of Saudi Arabia to protect United
States forces and interests in the region against hostile action by Iran and Iran-backed
groups. These forces, operating in coordination with the Government of the Kingdom of
Saudi Arabia, provide air and missile defense capabilities and support the operation of
United States fighter aircraft. The total number of United States forces in the Kingdom of
Saudi Arabia is approximately 2,120.
Since the March 2015 Saudi-led coalition intervention in Yemen, Congress has taken an active
role in debating and overseeing U.S. policy in the Arabian Peninsula.5 Members have considered
legislative proposals seeking to reduce Yemeni civilian casualties resulting from the coalition’s
operations; improve deteriorating humanitarian conditions; end restrictions on the flow of goods
and humanitarian aid; combat Iranian support for the Houthis; preserve maritime security in the
Bab al Mandab Strait; improve U.S. efforts to counter Al Qaeda and Islamic State forces in
Yemen; and/or support, condition, or end U.S. support to the Saudi-led coalition.
Beyond Yemen, many Members have referred to the conflict as an element of a broader regional
rivalry between Saudi Arabia and Iran, and discussed the conflict’s implications for the U.S.
effort to limit Iran’s malign regional influence. Others lawmakers have described the Yemen
conflict as indicative of what they perceive as problems in the U.S.-Saudi relationship, a concern
that deepened after the 2018 killing of Saudi journalist Jamal Khashoggi by Saudi government
personnel. Congress has considered and passed proposals to reject certain U.S. defense sales to
Saudi Arabia and the United Arab Emirates (UAE) and to direct an end to U.S. military
involvement in military operations related to the anti-Houthi campaign, but has not voted to
override presidential vetoes of related legislation.
Mixed results from attempts to limit U.S. support for the Saudi-led intervention in Yemen also
appear to be reinvigorating some Members’ interest in strengthening the role of Congress in
foreign policy vis-à-vis the executive branch.6 Debate in Congress over Yemen has featured
bipartisan statements of interest in asserting the prerogatives of the legislative branch to limit
executive branch power, specifically using war powers legislation and the appropriations and
authorization processes to curb U.S. military involvement in support of coalition operations.
Congressional scrutiny of U.S. policy in Yemen has also led to enacted and proposed legislative
changes to global authorities, such as the Department of Defense’s authority to enter into and use
acquisition and cross servicing agreements with partner militaries.7 The Trump Administration’s
invocation of emergency requirements to proceed with proposed arms sales to Saudi Arabia and
the UAE, including sales of air-to-ground munitions scrutinized in the context of the Yemen war,
has similarly led some in Congress to propose changes to underlying arms sales authorities
granted to the executive branch.8

5 Congress periodically addressed Yemen-related issues in annual authorization and appropriations legislation prior to
the 2015 Saudi-led intervention, such as providing security assistance to Yemeni government forces to counter terrorist
groups like Al Qaeda in the Arabian Peninsula (AQAP); addressing Yemeni detainees in Guantanamo Bay, Cuba;
overseeing the issuance of visas for Yemeni nationals traveling to the United States; countering human trafficking in
Yemen; and prohibiting U.S. assistance from being provided to Yemeni security forces that use child soldiers.

Sweeping, Bipartisan Legislation to Overhaul Congress’s Role in National Security,” July 20, 2021.

8 Section 1270 of the House-passed version of the FY2020 National Defense Authorization Act, H.R. 2500, would have

Congress and the War in Yemen: Oversight and Legislation 2015-2021

The Biden Administration has ended U.S. support to Saudi-led coalition offensive operations in
Yemen and has expanded U.S. diplomatic support for efforts to negotiate a settlement to the
Houthi-coalition conflict. Some legislative proposals in the 117th Congress have sought additional
changes to U.S. policy.
Conflict Overview and Root Causes of Crisis
The United Nations, nongovernmental organizations, and international relief agencies all have often described
Yemen’s ongoing humanitarian and food crisis as “man-made,” meaning it is a direct result of the ongoing armed
conflict that began in March 2015.9 More than six years ago, Saudi Arabia established a coalition (hereinafter
referred to as the Saudi-led coalition) and launched a military operation aimed at restoring the rule of Yemen’s
internationally recognized President Abdu Rabbu Mansour Hadi. Hadi’s government was being gradually supplanted
by an alliance comprised of the Iran-supported Houthi movement and loyalists of the previous President, Ali
Abdul ah Saleh (hereinafter referred to as Houthi-Saleh forces). The internationalization of Yemen’s conflict
reflects wider trends that have seen Iran seek to challenge the security of its regional rivals through the provision
of material support to state and non-state actors.
Although the current conflict began in 2015, its root causes are much deeper. A major factor in the conflict is
competition between political elites for primacy in Yemen and between sub-state actors and ruling elites for
influence. For decades, the most powerful political actor in Yemen had been former president Ali Abdul ah Saleh
who was kil ed in 2017. Saleh ruled northern Yemen from 1978 to 1990 and unified Yemen from 1990 to 2012.
His presidency began to unravel in 2011, when political unrest broke out throughout the Arab world. Popular
youth protests in Yemen were gradually supplanted by political elites jockeying to replace then-President Saleh.
Concerned that the political unrest and resulting security vacuum were strengthening terrorist elements, the
United States, Saudi Arabia, and other members of the international community attempted to broker a political
compromise. A transition plan was developed, and in 2012 former Vice President Abdu Rabbu Mansour Hadi
became president.
With the support of the United States, Saudi Arabia, and the United Nations Security Council, President Hadi
attempted to reform Yemen’s political system. Throughout 2013, key stakeholders convened a National Dialogue
Conference aimed at reaching broad national consensus on a new political order. However, in January 2014 it
ended without agreement.
One antigovernment group in particular, the northern Yemeni Houthi movement, sought to use violence to
reshape the political order.10 Within weeks of the National Dialogue Conference concluding, it launched an armed
offensive against various tribal allies of President Hadi. The Houthi were joined by the forces stil loyal to former
President Saleh, creating an alliance of convenience and emerging as a formidable opponent to President Hadi and
his allies. Ultimately, Houthi militants took over the capital and advanced from the capital all the way to Aden. In
March 2015, after President Hadi, who had fled to Saudi Arabia, appealed for international intervention, Saudi
Arabia and a hastily assembled international coalition launched a military offensive aimed at restoring Hadi’s rule
and evicting Houthi fighters from the capital and other major cities. Both sides have been fighting ever since.
Saudi Arabia and its coalition partners’ interest in developments in Yemen arguably reflects their concern about
regional security and threats to their territory and populations. The Houthis and other Iran-aligned actors
describe their cross-border attacks on Saudi Arabia and the United Arab Emirates as retaliatory and tactical, but
the attacks reinforce regional governments’ strategic concerns about Iran-backed armed groups and may
contribute to their reluctance to curtail their military intervention.

this provision in the final enacted version of the bill, S. 1790/P.L. 116-92.

Stressing Urgent Need For Support,” U.N. Secretary-General Press Release, April 25, 2017; and U.N. Special Envoy
for Yemen Martin Griffiths, Briefing to United Nations Security Council, June 15, 2021.
10 The Houthi movement was formed in the northern Yemeni governorate of Sa’dah (in the mountainous district of
Marran) in 2004 under the leadership of members of the Houthi family. Between 2004 and 2010, the central
government and the Houthis fought six wars in northern Yemen. Saudi Arabia supported the central government of
Yemen in these various military campaigns against a Houthi insurgency. With each successive round of fighting, the
Houthis improved their position, as antigovernment sentiment became more widespread amidst an aggrieved
population in a war-torn and neglected north. Although the Houthi movement originally sought an end to what it
viewed as Saudi-backed efforts to marginalize Zaydi communities and beliefs, its goals grew in scope and ambition in
the wake of the 2011 uprising and government collapse to embrace a broader populist, anti-establishment message.

Congress, the Obama Administration, and Yemen
(2015-2016)
2015
In the months following the March 2015 intervention, the Saudi-led coalition had made modest
but inconclusive gains on the ground, and civilian casualties from coalition air strikes were
drawing increasing international criticism. In Congress, several lawmakers began to express
concern through letters and statements about civilian casualties, the deteriorating humanitarian
situation in Yemen, and U.S. policy.11 In October 2015, 10 Members of Congress wrote a letter to
President Obama urging him to “work with our Saudi partners to limit civilian casualties to the
fullest extent possible.”12
By the fall of 2015, as the Obama Administration reportedly tried to balance its concern for
adherence to the laws of armed conflict with its support for Gulf partners,13 lawmakers began to
express concern over U.S. involvement in the coalition’s intervention by scrutinizing U.S. arms
sales to Saudi Arabia.14 When the Administration informally notified15 Congress of a proposed
sale of precision guided munitions (PGMs) to Saudi Arabia, some Senators sought to delay its
formal notification.16 After the formal notification in November 2015,17 the Senate Foreign
Relations Committee (SFRC) chair and ranking member jointly requested that the Administration
notify Congress 30 days prior to associated shipments, marking the first use of this prior-
notification request authority.18 No related joint resolutions of disapproval on proposed sales of
PGMs to the kingdom were introduced, but the delay and the request for additional notification
arguably demonstrated congressional concern.19

18 The request marked the first time that Congress has invoked an authority it added to the Arms Export Control Act in
December 2014 through an amendment included in the Naval Vessel Transfer Act of 2013 (P.L. 113-276). Section 201
of the Naval Vessel Transfer Act of 2013 (P.L. 113-276) added Section 36(i) to the AECA. Potentially applicable to
any foreign military sale requiring notification pursuant to Section 36(b) of the AECA, the 36(i) mechanism requires
both the chair and ranking member of either of the two committees of jurisdiction (Senate Foreign Relations
Committee/House Foreign Affairs Committee) to jointly request that the President provide such a “pre-shipment
notification” 30 days prior to a shipment. The pre-shipment notification would inform Congress that a shipment was
about to occur, but would not require or preclude Congress from taking further action to modify or block the shipment.
19 Although Congress has more than one legislative option it can use to block or modify an arms sale, one option
explicitly set out in law for blocking a proposed arms sale is the use of a joint resolution of disapproval as provided for
in Section 36(b) of the Arms Export Control Act (AECA). See, CRS Report RL31675, Arms Sales: Congressional
Review Process, by Paul K. Kerr.

2016
By the one-year anniversary of the Saudi-led intervention in Yemen, a more defined opposition20
to U.S. support for the coalition had begun to coalesce amid repeated international documentation
of human rights abuses21 and errant coalition air strikes.22 In April 2016, legislation was
introduced that sought to place conditions on future proposed sale notifications, previously
approved sales, or transfers of PGMs to Saudi Arabia (Table 4).23 Proposed amendments to
FY2017 defense legislation24 would have added some similar conditions on the use of funds to
implement sales of PGMs or prohibited the transfer of cluster munitions to Saudi Arabia.25 The
PGM amendment was not considered, but the cluster munitions amendment was defeated in a
June 2016 House floor vote.26
In the spring and summer of 2016, the United Nations held multiple rounds of peace talks in
Kuwait aimed at brokering an end to the conflict. From April 2016 to August 2016, the Saudi-led
coalition largely spared Yemen’s capital Sana’a from aerial strikes as part of its commitment to
the cessation of hostilities. When U.N.-mediated peace talks collapsed in August 2016, the Saudi-
led coalition resumed bombing and the war intensified.
During the summer of 2016, the Obama Administration reduced some of the U.S. support for
Saudi Arabia’s air campaign in Yemen by withdrawing U.S. personnel assigned to a joint U.S.-
Saudi planning cell.27 Nevertheless, overall U.S.-Saudi cooperation continued and, in August
2016, the Obama Administration notified Congress of a proposed sale of M1A2S tanks to Saudi
Arabia. In response, some lawmakers wrote to request that President Obama withdraw the
proposal, citing concerns about Yemen.28 In September 2016, joint resolutions of disapproval of
the proposed tank sale were introduced in the Senate (S.J.Res. 39) and House (H.J.Res. 98). On
September 21, 2016, the Senate voted to table a motion to discharge the SFRC from further
consideration of S.J.Res. 39 (71-27, Record Vote 145).29 During debate over the motion, many

21 In April 2016, the “Saudi Arabia-led coalition” was listed alongside other parties to the conflict in Yemen in the
annex of the annual report of United Nations Secretary General on Children and Armed Conflict for attacks that
resulted in the killing and maiming attacks of children in Yemen. In July 2016, then-U.N. Secretary General Ban Ki-
moon alleged that Saudi Arabia had threatened to reduce its funding for U.N. programs if the coalition was not
removed from the report annex, an allegation that Saudi leaders denied. In August 2016, the Secretary General said
“the Saudi Arabia-led coalition was removed from the annexes, pending the conclusions of a review. ... But I want to
repeat: the content of the report stands.” See, U.N. Blacklists Saudi-led Coalition for Killing Children in Yemen,

Senators argued in favor of continued U.S. support for Saudi Arabia, with Senator Lindsey
Graham remarking “To those who want to vote today to suspend this aid to Saudi Arabia, people
in Iran will cheer you on.”30
In the wake of an October 2016 Saudi air strike on a funeral hall in Sana’a that killed 140 people,
the Obama Administration initiated a review of U.S. security assistance to Saudi Arabia.31 Based
on that review, it put a hold on a planned sale of precision guided munitions (PGMs) to Saudi
Arabia and limited intelligence sharing, but maintained counterterrorism cooperation and
refueling for coalition aircraft.32
In the final months of the Obama Administration, U.S. Armed Forces exchanged fire with Houthi-
Saleh forces. In October 2016, Houthi-Saleh forces launched anti-ship missiles at U.S. Navy
vessels on patrol off the coast of Yemen. The attacks against the U.S. ships marked the first time
U.S. Armed Forces had come under direct fire in the war. The Obama Administration responded
to the attacks against U.S. naval vessels by directing the Armed Forces to fire cruise missiles
against Houthi-Saleh radar installations. The Obama Administration described the U.S. strikes as
self-defense and indicated that it did not want to deepen its direct involvement in the conflict.33 In
August and November 2016, then-Secretary of State John Kerry made several attempts to broker
a peace initiative in Oman, but the parties rejected his efforts.
Leahy Law and Saudi-led Coalition Strikes in Yemen
Section 620M of the Foreign Assistance Act of 1961 (FAA), as amended, prohibits the furnishing of assistance
authorized by the FAA and the Arms Export Control Act to any foreign security force unit where there is
credible information that the unit has committed a gross violation of human rights. The State Department and U.S.
embassies overseas implement Leahy vetting to determine which foreign security individuals and units are eligible
to receive U.S. assistance or training. In October 2016, Senator Patrick Leahy remarked that “The humanitarian
crisis in Yemen has received too little attention, and it directly, or indirectly, implicates us. . The reports of civilian
casualties from Saudi air attacks in densely populated areas compel us to ask if these operations, supported by the
United States, violate [that law].”34
Analysis
By the end of the 114th Congress, the war in Yemen was becoming a more significant foreign
policy issue for lawmakers. While a growing number of Members were becoming critical of the
U.S. role in supporting the Saudi-led coalition amid a deteriorating humanitarian situation in
Yemen, more lawmakers still seemed to view the conflict through a regional lens rather than as a
localized affair.35 Amid significant congressional opposition to the 2015 nuclear agreement with
Iran (Joint Comprehensive Plan of Action or JCPOA), some Members described Iran’s support
for the Houthi movement and the broader conflict in Yemen as an example of Iran’s malign
regional activities not directly addressed by the JCPOA. When Houthis targeted Gulf state

infrastructure on land and vessels at sea, U.S. officials and nongovernment observers cited their
behavior as evidence of Iran’s growing capabilities to threaten U.S. and Gulf security.36
While some Members described the Yemen conflict primarily a proxy war between the Iran-
backed Houthis and the Saudi-led coalition, others portrayed it as a test of long-standing U.S.
commitments to supporting Saudi Arabian security.37 Supporters of the relationship, while
acknowledging that Saudi Arabia’s conduct of the war was at times problematic, argued that to
curtail U.S. arms sales or other defense support to the kingdom would weaken a vital partner that
was under threat from a hostile nonstate actor on its southern border.38
Others lawmakers charged that continued U.S. support for the coalition was not improving
coalition behavior but was damaging the U.S. reputation for upholding commitments to
international law and human rights.39 The 114th Congress did not enact legislation to limit U.S.
arms sales to Saudi Arabia, but these years marked the beginning of the broader congressional
debate that has continued.40
As the Trump Administration prepared to assume office, human rights organizations and aid
groups were pressing Congress to pay more attention to the growing humanitarian crisis in
Yemen. Though the Obama Administration had taken some steps, particularly in late 2016, to
limit U.S.-coalition cooperation and restrict deliveries of PGMs to Saudi Arabia, some
nongovernmental groups deemed this insufficient. According to Human Rights Watch, “Whatever
conditionality the Obama administration thought it had created—in holding up the transfer of
precision munitions near the tail end of Obama’s term and suspending cluster munition transfers
earlier—ultimately did not have meaningful impact in reining in the continued Saudi-led coalition
attacks on civilians.”41
Congress, the Trump Administration, and Yemen
(2017-2020)
2017
In his first year in office, President Trump sought to improve relations with Saudi Arabia, counter
Iran, and increase U.S. counterterrorism activity in Yemen, while at the same time his
Administration also took strong positions at times on the need for the coalition to improve
humanitarian access, pursue a settlement to the conflict, and take measures to prevent civilian
casualties.
From the beginning of his Administration, President Donald Trump signaled strong support for
the Saudi-led coalition’s operations in Yemen as a bulwark against Iranian regional interference.

restrictions on U.S. arms sales and intelligence sharing to the coalition.42 On March 19, 2017, just
before his visit to Saudi Arabia, President Trump notified Congress that he was proceeding with
three proposed direct commercial sales of precision guided munitions technology deferred by the
Obama Administration, subject to congressional review.43
In May 2017, the Trump Administration officially notified Congress of its intention to proceed
with sales of precision-guided munitions technologies that the Obama Administration had
deferred, while announcing plans to increase training for Saudi Arabia’s air force on both
targeting and the Law of Armed Conflict.44 Congress debated another resolution of disapproval
(S.J.Res. 42) of these proposed PGM sales in June 2017 (see below). After completing the policy
review in July 2017, President Trump directed his Administration “to focus on ending the war and
avoiding a regional conflict, mitigating the humanitarian crisis, and defending Saudi Arabia’s
territorial integrity and commerce in the Red Sea.”45
U.S. Counterterrorism Policy in Yemen 2015-2020
During both the Obama and Trump Administrations, the United States sustained counterterrorism operations
against Al Qaeda in the Arabian Peninsula (AQAP) and various affiliates of the Islamic State in Yemen. Throughout
the conflict in Yemen, the United States targeted high-value individuals successful y within terrorist organizations.
For example, in 2015, a U.S. strike kil ed then-AQAP leader Nasser al Wuhayshi.
At the start of the Trump presidency, the United States markedly increased the tempo of strikes.46 According to
one report, in early 2017, the President declared parts of three Yemeni provinces to be an “area of active
hostilities” where more permissive rules of engagement reportedly applied.47 In January 2017, Ryan Owens, a
Navy SEAL, died during a counterterrorism raid in which between 4 and 12 Yemeni civilians also were kil ed,
including several children. One of the children was a U.S. citizen. The raid was the Trump Administration’s first
acknowledged counterterror operation.
In subsequent years, these operations intensified and reportedly kil ed a number of prominent AQAP targets. In
2018, U.S. officials claimed that one of the most high-value members in the AQAP organization, bomb-maker
Ibrahim al Asiri, had been kil ed in a U.S. air strike.48 On January 4, 2019, the Department of Defense announced
that a U.S. precision strike had kil ed Jamal al Badawi, one of the primary Yemeni terrorists involved in the 2000
USS Cole bombing. In February 2020, the United States announced that it had kil ed AQAP leader Qassim al Raimi
in a drone strike.

Congress and the War in Yemen: Oversight and Legislation 2015-2021

As President Trump entered office, the dynamics of the conflict in Yemen were changing, and the
Saudi-led coalition launched a new offensive along Yemen’s 280-mile western coastal plain
ultimately aimed at taking the strategic Houthi-held port city of Hudaydah (Yemen’s highest
capacity port). In early 2017, some Members of Congress responded to the coalition’s gradual
advance toward Hudaydah, coupled with an ongoing deterioration in humanitarian conditions, by
imploring the Administration to improve aid access and negotiate a cease-fire. In March 2017,
several House Members wrote a letter to then-Secretary of State Rex Tillerson urging him to “use
all U.S. diplomatic tools to help open the Yemeni port of Hodeida [Hudaydah] to international
humanitarian aid organizations.”49 A month later, another group of House Members wrote to
President Trump stating that “any decision by the administration to engage in direct U.S.
hostilities against Yemen’s Houthis must be subject to a congressional debate and vote.”50
On June 13, 2017, the Senate debated another resolution (S.J.Res. 42) to disapprove of three
direct commercial sales of PGMs to Saudi Arabia. During Senate floor consideration over the
motion to discharge the Senate Foreign Relations Committee from further consideration of
S.J.Res. 42, Members once again weighed various issues, such as the U.S.-Saudi bilateral
relationship, countering Iran, and limiting U.S. involvement in the war in Yemen. Some
lawmakers suggested that U.S. arms sales and military support to the coalition had enabled
alleged violations of international humanitarian law, while others argued that continuing U.S.
support to the coalition improves its effectiveness and helps minimize civilian casualties.
For example, during floor debate, Senator Graham argued that “If we are worried about collateral
damage in Yemen, I understand the concern. Precision weapons would help that cause, not hurt
it.”51 Senator Murphy responded, saying “What we are asking for is to hold off on selling these
precision-guided munitions until we get some clear promise—some clear assurance—from the
Saudis that they are going to use these munitions only for military purposes and that they are
going to start taking steps—real steps, tangible steps—to address the humanitarian crisis.”52 On
June 13, 2017, the Senate voted to reject the motion to discharge the Senate Foreign Relations
Committee from further consideration of S.J.Res. 42 (47-53, Record Vote 143), and a companion
resolution was not taken up in the House (H.J.Res. 102).
Representative Khanna introduced a concurrent resolution (H.Con.Res. 81) pursuant to the War
Powers Resolution (P.L. 93-148) in a bid to end U.S. support for the coalition’s military
intervention. After consultation between House leaders and supporters of the resolution on a
compromise approach, the House agreed to delay expedited consideration of the resolution until
after the November 2018 election and then adopted a nonbinding alternative (H.Res. 599, 366-30,
1 Present, Roll no. 623).53
In November 2017, the conflict deepened when a Houthi-fired missile with alleged Iranian
origins landed deep inside Saudi Arabia and the coalition instituted a full blockade of all of
Yemen’s ports, including the main port of Hudaydah, exacerbating the country’s humanitarian
crisis.54 The White House issued four press statements on the conflict between November 8 and

December 8, including a statement on December 6 in which President Trump called on Saudi
Arabia to “completely allow food, fuel, water, and medicine to reach the Yemeni people who
desperately need it. This must be done for humanitarian reasons immediately.”55
On December 20, 2017, the Saudi-led coalition announced that it would end its blockade of
Hudaydah port for a 30-day period and permit the delivery of four U.S.-funded cranes to Yemen
to increase the port’s capability to off-load commercial and humanitarian goods.56 The next day,
the White House issued a statement welcoming “Saudi Arabia’s announcement of these
humanitarian actions in the face of this major conflict.”57
2018
As the Saudi-led coalition intervention entered its fourth year, some in the Senate proposed use of
the War Powers Resolution as a tool for ending U.S. support for the coalition’s military
intervention. On February 28, 2018, Senator Bernie Sanders introduced S.J.Res. 54, a joint
resolution to “direct the removal of United States Armed Forces from hostilities in the Republic
of Yemen that have not been authorized by Congress (except for those U.S. forces engaged in
counterterrorism operations directed at al Qaeda or associated forces).” The Senate continued
considering proposals to direct the President to remove U.S. forces from Yemen (see Table 3
below).
Throughout 2018, there was disagreement between Congress and the Trump Administration and
within Congress itself, as to whether U.S. forces assisting the Saudi-led coalition have been
introduced into active or imminent hostilities for purposes of the War Powers Resolution. Some
Members claimed that by providing support to the Saudi-led coalition, U.S. forces have been
introduced into a “situation where imminent involvement in hostilities is clearly indicated” based
on the criteria of the War Powers Resolution.58 The Trump Administration disagreed. In February

agencies to warn of impending famine. The total closure of all Yemeni ports lasted 20 days; the Saudi-led coalition
then announced that it would begin allowing humanitarian aid to resume entering Hudaydah port—but not commercial
shipments of food and fuel. The Saudi-led coalition argued that the Houthis earn hard currency by taxing fuel imports.
Yemen imports 80% of its food from commercial suppliers rather than from humanitarian sources.

56 In late 2017, Senators Todd Young and Christopher Murphy placed a hold on the confirmation of the State
Department’s nominee for legal advisor, Jennifer Newstead, until the Administration took certain steps to address the
coalition’s blockade of Yemen. Dan De Luce and Robbie Gramer, “GOP Senator Presses Trump Administration Over
Deadly Saudi Blockade in Yemen,” Foreign Policy, December 4, 2017; and, Dan De Luce, “Trump Nominee Concedes
Saudi Siege of Yemen Could Be Violating U.S. Law,” Foreign Policy, December 19, 2017. On December 14, Senator
Young sent a letter to President Trump thanking the President for his December 6 statement, while asserting that, per
the Foreign Assistance Act of 1961 as amended (22 U.S. Code §2378-1(a)), the coalition’s blockade triggers a
prohibition on U.S. foreign assistance to Saudi Arabia. Newstead was confirmed by the Senate on December 19 after
promising the Senate Foreign Relations Committee to consider evidence of any possible foreign government restriction
of the delivery of U.S. humanitarian assistance to Yemen in determining whether to apply statutory prohibitions found
in 22 U.S. Code §2378-1(a). See Senator Todd Young, Young: Law Triggered by Saudi Arabia’s Actions in Yemen,

Congress and the War in Yemen: Oversight and Legislation 2015-2021

2018, the Acting Department of Defense General Counsel wrote to Senate leaders describing the
extent of current U.S. support, and reported that “the United States provides the KSA [Kingdom
of Saudi Arabia]-led coalition defense articles and services, including air-to-air refueling;59
certain intelligence support; and military advice, including advice regarding compliance with the
law of armed conflict and best practices for reducing the risk of civilian casualties.”60
On March 20, 2018, the Senate considered S.J.Res. 54. During floor debate, arguments centered
on a number of issues, ranging from concern over exacerbating Yemen’s humanitarian crisis to
reasserting the role of Congress in authorizing the use of armed force abroad. After then-Foreign
Relations Committee Chairman Senator Bob Corker promised to propose new legislation and
hold hearings scrutinizing U.S. policy in Yemen, a majority of Senators voted to table a motion to
discharge the Foreign Relations committee from further consideration of S.J.Res. 54. Senator
Robert Menendez made remarks expressing conditional support for Senator Corker’s approach, a
majority of committee members voted to table the motion.61
The Senate Foreign Relations Committee held a hearing on Yemen a month later. In parallel
testimony before Congress, U.S. defense officials stated that while the United States refueled
Saudi aircraft and provided advice on targeting techniques, CENTCOM did not track coalition
aircraft after they were refueled and did not provide advice on specific targets.62 Then-Assistant
Secretary of Defense for International Security Affairs Robert S. Karem testified that “It’s correct
that we do not monitor and track all of the Saudi aircraft aloft over Yemen.”63 During the same
hearing, U.S. officials acknowledged that pressure from Congress has altered how the
Administration was dealing with the coalition over the Yemen conflict. Acting Assistant Secretary
of State for Near Eastern Affairs David Satterfield told Senator Todd Young and the SFRC the
following:
Senator, your efforts, the efforts of your colleagues in this body and on this Committee
have been exceedingly helpful in allowing the Administration to send a message from
whole of government regarding the very specific concerns we have over any limitations,
restrictions, constraints on the ability of both humanitarian and commercial goods
specifically to include fuel to have unrestricted and expeditious entry into Yemen. And that

59 Until November 2018, U.S. in-flight refueling to the militaries of Saudi Arabia and the United Arab Emirates (UAE)
was conducted pursuant to the terms of bilateral Acquisition and Cross-Servicing Agreements (ACSAs) between the
Department of Defense and the respective ministries of each country. Some retransfers of fuel services were provided
to Saudi-led coalition members, and in 2015, Saudi Arabia received general purpose bombs retransferred by the United
Arab Emirates. ACSA agreements are governed by 10 U.S.C. §2341-2350. The U.S. agreement with Saudi Arabia was
signed in May 2016. Prior to May 2016, a “Joint Staff Execute Order signed on March 27, 2015, directed DOD to
provide aerial refueling support to the SLC [Saudi-led coalition], if requested, and stated that the support would be
provided on a reimbursable basis either through foreign military sales (FMS) or an ACSA.” U.S. Government

messaging which comes from us, the Executive Branch, also comes from this body is
extremely important.64
After the promised hearing, the Senate Foreign Relations Committee also proposed new
legislation to place conditions on U.S. assistance to the coalition. In May, the committee reported
S.J.Res. 58 to the Senate; it would have prohibited the obligation or expenditure of U.S. funds for
in-flight refueling operations of Saudi and Saudi-led coalition aircraft that were not conducting
select types of operations if certain certifications cannot be made and maintained.65
The Senate Armed Services Committee incorporated the provisions of the SFRC-reported text of
S.J.Res. 58 as Section 1266 of the version of the FY2019 National Defense Authorization Act
(NDAA) that it reported to the Senate on June 5, 2018 (S. 2987). The provision was modified
further and passed by both the House and Senate as Section 1290 of the conference version of the
FY2019 NDAA (H.R. 5515, see textbox below). It was signed into law as P.L. 115-232 in mid-
August, giving the Administration until mid-September 2018 to make certain certifications. In a
statement accompanying the President’s signing of P.L. 115-232 into law, President Trump
objected to provisions such as Section 1290, stating the Administration’s view that such
provisions “encompass only actions for which such advance certification or notification is
feasible and consistent” with “[his] exclusive constitutional authorities as Commander in Chief
and as the sole representative of the Nation in foreign affairs.”66
As Congress continued to question the role of the United States in supporting coalition operations
in Yemen, the pace and scale of fighting on the ground increased dramatically by the summer of
2018. On June 12, 2018, the Saudi-led coalition launched “Operation Golden Victory,” aimed at
retaking the Red Sea port city of Hudaydah. As coalition forces engaged Houthi militants in and
around Hudaydah, humanitarian organizations warned that if port operation ceased, famine could
become widespread throughout northern Yemen. On June 12, nine Senators wrote a letter to then-
Secretary of State Michael Pompeo and then-Secretary of Defense James Mattis saying, “We are
concerned that pending military operations by the UAE and its Yemeni partners will exacerbate
the humanitarian crisis by interrupting delivery of humanitarian aid and damaging critical
infrastructure. We are also deeply concerned that these operations jeopardize prospects for a near-
term political resolution to the conflict.”67
Several weeks later, Senator Robert Menendez, the ranking member on the Senate Foreign
Relations Committee, placed a hold on a potential U.S. sale of precision guided munitions to
Saudi Arabia and the UAE. In a June 28 letter to Secretary of State Pompeo and Secretary of
Defense Mattis, Senator Menendez said,
I am not confident that these weapons sales will be utilized strategically as effective
leverage to push back on Iran’s actions in Yemen, assist our partners in their own self-
defense, or drive the parties toward a political settlement that saves lives and mitigates

65 The joint resolution identified several certification criteria, although, reported as amended by the committee, it would
have enabled the Secretary of State to waive the certification requirement for national security purposes if the Secretary
provided an unclassified explanatory justification to the appropriate committees. The joint resolution also would have
required a report on, among other things, U.S. objectives in Yemen and a detailed strategy to accomplish those
objectives.

humanitarian suffering.... Even worse, I am concerned that our policies are enabling
perpetuation of a conflict that has resulted in the world’s worst humanitarian crisis.68
Congress Restricts In-Flight Refueling for Coalition Aircraft
Section 1290 of P.L. 115-232 states that potential restrictions on the use of U.S. funds for in-flight refueling of
coalition aircraft would not apply to certain types of operations, including missions related to Al Qaeda and the
Islamic State or “related to countering the transport, assembly, or employment of ballistic missiles or components
in Yemen.” Under the final version of the provision, the Administration was required to certify that the Saudi and
Emirati governments were undertaking

an urgent and good faith effort to support diplomatic efforts to end the civil war in Yemen;

appropriate measures to alleviate the humanitarian crisis in Yemen by increasing access for Yemenis to food,
fuel, medicine, and medical evacuation, including through the appropriate use of Yemen’s Red Sea ports,
including the port of Hudaydah, the airport in Sana’a, and external border crossings with Saudi Arabia; and

demonstrable actions to reduce the risk of harm to civilians and civilian infrastructure resulting from military
operations of the Government of Saudi Arabia and the Government of the United Arab Emirates in Yemen,
including by (1) complying with applicable agreements and laws regulating defense articles purchased or
transferred from the United States, and (2) taking appropriate steps to avoid disproportionate harm to
civilians and civilian infrastructure.
With specific regard to Saudi Arabia, the Administration also was required certify that “the Government of Saudi
Arabia is undertaking appropriate actions to reduce any unnecessary delays to shipments associated with
secondary inspection and clearance processes other than [the United Nations Verification and Inspections
Mechanism].” The Administration could waive the certification requirement if certain explanatory submissions
were made. Reporting and strategy submission requirements also were included in the final version.
After the Trump Administration issued a certification to allow continued in-flight refueling, it subsequently decided
to end that type of support (see below). The next year, Congress moved to codify a prohibition on the provision
of in-flight refueling for a two-year period (Section 1273 of P.L. 116-92). In the 117th Congress, the House
approved an amendment to its version of the 2022 National Defense Authorization Act to extend this prohibition
for two further years (House Rules Committee Amendment 852, H.R. 4350). The provision was included in the
final version of the act (Sec. 1339, S. 1605/P.L. 117-81; see Table 1).
On August 9, the coalition conducted an air strike that hit a bus in a market near Dahyan, Yemen,
in the northern Sa’ada governorate adjacent to the Saudi border. The strike reportedly killed 51
people, 40 of whom were children. The coalition claimed that its air strike was a “legitimate
military operation” conducted in response to a Houthi missile attack on the Saudi city of Jizan a
day earlier that had killed a Yemeni national in the kingdom. The U.S. State Department called on
the Saudi-led coalition to conduct a “thorough and transparent investigation into the incident.”69
Several Members of Congress wrote to the Administration seeking additional information
regarding U.S. operations in the wake of the August 2018 coalition strike at Dahyan.70 Several
Senators also submitted an amendment to the FY2019 Defense Department appropriations act
(H.R. 6157) that would have prohibited the use of funds made available by the act to support the
Saudi-led coalition operations in Yemen until the Secretary of Defense certifies in writing to
Congress that the coalition air campaign “does not violate the principles of distinction and
proportionality within the rules for the protection of civilians.” The provision would not have
applied to support for ongoing counterterrorism operations against Al Qaeda and the Islamic State
in Yemen.

Congress and the War in Yemen: Oversight and Legislation 2015-2021

On September 12, Secretary of State Pompeo issued a certification that would allow the use of
FY2019 defense funds to support in-flight refueling of coalition aircraft to continue, per the terms
of Section 1290 (see discussion above) of the FY2019 National Defense Authorization Act
(NDAA, P.L. 115-232). Some Members of Congress criticized the Administration’s actions,
asserting that the coalition had not met the act’s specified benchmarks for avoiding civilian
casualties in Yemen.71
On September 26, several House Members introduced H.Con.Res. 138, which sought to direct the
President to remove U.S. Armed Forces from hostilities in Yemen, except for Armed Forces
engaged in operations authorized under the 2001 Authorization for Use of Military Force, within
30 days unless and until a declaration of war or specific authorization for such use has been
enacted into law. In response to H.Con.Res. 138, the Administration referenced its earlier detailed
argument in objecting to S.J.Res. 54, expressing the President’s view that U.S. forces supporting
Saudi-led coalition operations are not engaged in hostilities in Yemen.72
By late 2018, the prospect of widespread famine in Yemen, coupled with international reprobation
over the killing of Jamal Khashoggi by Saudi officials, had created pressure on the
Administration and the coalition to accelerate moves toward peace talks. On October 30, then-
Secretary of Defense Mattis and Secretary of State Pompeo called for all parties to reach a cease-
fire and resume negotiations. On November 9, Secretary Mattis further announced that effective
immediately, the coalition would use its own military capabilities—rather than U.S. capabilities—
to conduct in-flight refueling in support of its operations in Yemen.73
Though fighting continued along several fronts, Special Envoy of the United Nations Secretary-
General for Yemen Martin Griffiths brokered a cease-fire on December 13, 2018, centered on the
besieged Red Sea port city of Hudaydah.74 As part of the U.N.-brokered deal (known as the
Stockholm Agreement), the coalition and the Houthis agreed to redeploy their forces outside
Hudaydah city and port.75 The United Nations agreed to chair a Redeployment Coordination
Committee (RCC) to monitor the cease-fire and redeployment. The Security Council praised the
Stockholm Agreement as a first step toward broader de-escalation and a possible road map to a
comprehensive peace settlement.76
Also on December 13, 2018, the Senate amended and passed S.J.Res. 54 (56-41), which, among
other things, directed the President to remove U.S. forces from hostilities in Yemen, except U.S.
forces engaged in operations directed at Al Qaeda or associated forces. In the House, lawmakers
twice approved rules containing provisions that made similar resolutions directing the President
to remove U.S. forces from hostilities in Yemen ineligible for expedited consideration (H.Res.

75 On December 6, 2018, the warring parties to the conflict in Yemen convened in Sweden under the auspices of the
United Nations to discuss various de-escalation proposals and a possible road map to a comprehensive peace
settlement. The talks were the first formal negotiations since 2016. After a week of negotiations, all sides agreed to the
Stockholm Agreement, which consists of three components; a cease-fire around the port city of Hudaydah, a prisoner
swap, and a statement of understanding that all sides would form a committee to discuss the war-torn city Taiz.

1142 and H.Res. 1176).77 On December 13, the Senate also passed S.J.Res. 69, which, among
other things, expressed the sense of the Senate that Saudi Crown Prince Mohammed bin Salman
was responsible for the murder of the journalist Jamal Khashoggi and that there was no statutory
authorization for United States involvement in hostilities in the Yemen civil war.
2019
For the first several months of 2019, implementation of the Stockholm Agreement stalled.
According to Special Envoy Griffiths, “the initial timelines were rather ambitious” and “a
complex situation on the ground” was stalling U.N.-backed efforts.78 The Stockholm Agreement
did not specify which local actors were to assume responsibility for security in Hudaydah after
both parties redeployed.79 According to reporting by the United Nations, initial implementation of
the Stockholm Agreement was hindered by an overall lack of trust and a reluctance to make
operational concessions outside of a comprehensive political agreement. On February 17, 2019,
the United Nations announced that “The parties reached an agreement on Phase 1 of the mutual
redeployment of forces” whereby the Houthis would withdraw from Hudaydah port and the
Saudi-led coalition would move out of the eastern outskirts of Hudaydah city.80
At the February 2019 Ministerial to Promote a Future of Peace and Security in the Middle East in
Warsaw, Poland, members of the self-described “quad” (United States, United Kingdom, Saudi
Arabia, and the United Arab Emirates) met to coordinate their policy toward the Yemen conflict.
The quad emphasized the importance of implementing the Stockholm Agreement, the problematic
role Iran plays in arming and financing the Houthis, and the need for additional humanitarian
assistance. The foreign ministers comprising the quad also “expressed full support for Saudi
Arabia and its legitimate national security concerns and called for an immediate end to such
attacks by Houthi forces and their allies.”
In February 2019, CNN reported that Saudi Arabia and the UAE had provided U.S. military
equipment (armored vehicles) to local Yemeni units fighting the Houthis in possible violation of
end-user foreign military sale or direct commercial sale agreements.81 The coalition denied these
charges, while the U.S. State Department said that it was “seeking additional information” on the
issue.82 In Senate and House hearings in early February, some Members expressed concern about
end-use monitoring of equipment provided to the coalition.83

On February 7, 2019, Senator Robert Menendez, ranking member on the Senate Foreign
Relations Committee, introduced S. 398, the Saudi Arabia Accountability and Yemen Act of 2019
(Table 2). This bill, which was originally introduced in the 115th Congress, would have, among
other things, legislatively required an end to in-flight refueling for Saudi-led coalition operations
in Yemen, suspended certain arms sales to the kingdom, sanctioned persons blocking
humanitarian access in Yemen, and sanctioned persons supporting the Houthis in Yemen. The
Senate Foreign Relations Committee reported the bill to the Senate in July 2019.
In response to reporting by the New York Times on the use of child soldiers by the Saudi-led
coalition, 13 Members of Congress wrote to Secretary Pompeo on February 15, 2019, seeking
information about the accuracy of the reports, and about whether these children had been
provided U.S.-made weapons and uniforms. Coalition officials denied the reports. Saudi Arabia
and the UAE were not included on the annual U.S. list of countries using child soldiers, although
the 2019 Trafficking in Persons report detailed continuing concerns about the government of
Yemen’s willingness and ability to end child soldier use by its forces and others.84
On February 13, 2019, the House passed H.J.Res. 37 (248-177), a joint resolution originally
introduced in the 115th Congress (S.J.Res. 54), “Directing the removal of United States Armed
Forces from hostilities in the Republic of Yemen that have not been authorized by Congress.”
Prior to its passage by the House, the White House issued a State of Administration Policy in
which the Administration argued that “the premise of the joint resolution is flawed” because the
United States had provided only “limited support to member countries of the Saudi-led coalition”
and U.S. forces providing such intelligence and logistics support were not engaged in hostilities.
Section 4 of H.J.Res. 37 includes a rule of construction stating that “Nothing in this joint
resolution may be construed to influence or disrupt any intelligence, counterintelligence, or
investigative activities conducted by, or in conjunction with, the United States Government.”
In March, the Senate passed S.J.Res. 7 (54-46), the companion resolution to H.J.Res. 37. The
House passed S.J.Res. 7 (247-175) on April 4. President Trump vetoed the resolution on April 16,
citing a concern that the resolution would weaken his constitutional authorities as Commander in
Chief, harm bilateral relationships, and negatively affect efforts to prevent civilian casualties and
prevent the spread of terrorist organizations in the Arabian Peninsula.85 House Majority Leader
Steny Hoyer responded to the presidential veto message stating that “the fight is not yet over, and
the House will explore further legislation and conduct rigorous oversight.”86
On May 2, 2019, the resolution failed to garner the 67 votes needed to override the veto in the
Senate (53-45). Senate Majority Leader Mitch McConnell reiterated his opposition to what he
referred to as the false premises of the measure: “We’re not parties to the civil war in Yemen.
We’re no longer providing air-to-air refueling. More importantly, the measure would make it
actually more difficult to prevent the loss of innocent lives.”87 Text from the House-passed
version of H.J.Res. 37 subsequently was added to the House version of the FY2020 Defense
appropriations act (Title X of H.R. 2968) and passed by the House, but not included in the final
version of the act.

Houthi forces began handing over control of Hudaydah and two other ports on the Red Sea on
May 10, in accordance with the first phase of redeployment laid out in the Stockholm Agreement.
Hadi government officials subsequently questioned the legitimacy of the withdrawal, with the
Information Minister calling it a “theatrical play”; Special Envoy Griffiths stated in a briefing to
the U.N. Security Council on May 15 that the Houthis had complied with the withdrawal.88
Though mediators had expressed hope that the Stockholm Agreement would lead to broader
peace negotiations, the Houthis escalated their drone and ballistic missile attacks against Saudi
Arabia during the summer of 2019. The Houthis called these attacks their “airport for airport”
campaign, stating that they would target Saudi civilian airports for as long as the Saudi-led
coalition maintains its closure of Sana’a airport. The Houthis launched multiple unmanned aerial
vehicle (UAV) attacks against regional airports in Saudi Arabia (Jizan, Najran, and Abha), forcing
the suspension of flights, damaging runways, and killing several civilians. Iran is believed to be
the original source of UAV technology and knowledge transfer to the Houthis.89 However, the
Houthis may have begun manufacturing their own UAVs. According to Jane’s Defence, “the
available evidence suggests that Ansar Allah is increasingly making use of parts that are
commercially available on the international market to develop new UAV designs.”90
On May 24, 2019, the Trump Administration formally notified Congress of immediate foreign
military sales and direct commercial sales of training, equipment, and weapons with a possible
value of more than $8 billion, including sales of precision guided munitions (PGMs) to Saudi
Arabia and the UAE, and the gift transfer of PGMs by the UAE to Jordan. Other notified sales
included, among others, F-15 engines and support for Saudi Arabia and AH-64 equipment,
Javelin Anti-Tank Missiles, and Patriot Guidance Enhanced Missiles for the UAE. In the
Administration’s justification for the emergency sales to Congress, it described a “rapidly-
evolving security situation in the region” and noted, among others, the threat posed by Iranian-
backed Houthis, who have “publicly threatened to increase operations targeting vital military
targets in the United Arab Emirates, Saudi Arabia, and Saudi-Led Coalition positions in
Yemen.”91
On June 5, 2019, a group of seven Senators introduced 22 separate joint resolutions of
disapproval against the sales. One cosponsor, Senator Lindsey Graham, expressed in a statement
his concern about “the precedent these arms sales would set by having the Administration go
around legitimate concerns of Congress.”92 The Senate adopted all 22 of the measures. Three of
the measures focused on proposed sales of air-to-ground munitions were adopted by the House
and Senate and vetoed by the President (see Table 2).
In summer 2019, the UAE unilaterally withdrew most of its forces from Yemen. The UAE had
been Saudi Arabia’s primary partner in the coalition war against the Houthis. The UAE’s local
partners in southern Yemen, the Transitional Political Council for the South (aka Southern
Transitional Council, STC), attempted to seize more power in Aden from the Hadi government

following the UAE’s withdrawal. Violent confrontations ensued between STC and pro-Hadi
forces. Although Saudi Arabia and the UAE brokered a power-sharing agreement between Hadi’s
supporters and the STC in November 2019, implementation of that deal stalled, leaving the STC
ensconced in the South, the Houthis controlling the north, and the Hadi government isolated.
Beyond the ground war in Yemen, the Houthis continued to launch missile, rocket, and unmanned
aerial vehicle (UAV)93 attacks intermittently against Saudi Arabian population centers and energy
infrastructure. After sophisticated air attacks against Saudi Arabian oil fields of Abqaiq and
Khurais in September 2019, attacks widely attributed to Iran but claimed by the Houthis, the
Houthis announced that they would suspend missile and UAV attacks against Saudi Arabia.
Between September and December 2019, Saudi, Yemeni government, and Houthi representatives
engaged in talks aimed at de-escalating the fighting. The talks were accompanied by several
confidence-building measures, such as prisoner exchanges and medical evacuation flights from
Sana’a to Amman, Jordan. However, in January 2020, the Houthis resumed their UAV and missile
attacks against Saudi Arabia (see below).94
Section 1273 of the FY2020 National Defense Authorization Act (P.L. 116-92) codified (for a
two-year period) an existing Department of Defense policy to end in-flight refueling of Saudi-led
coalition aircraft engaged in hostile operations in Yemen. After President Trump signed the act, he
issued a signing statement asserting that
Several provisions of the Act, including sections 1254, 1273, 1698(a), and 2810, purport
to restrict the President’s authority to manage personnel, materiel, and logistical matters in
the manner the President believes to be necessary or advisable for the successful conduct
of military missions and foreign affairs….My Administration will implement these
provisions consistent with the President’s authority as Commander in Chief....
Other provisions proposed, considered, and adopted in the House during 2019 debate over the
National Defense Authorization Act were not included in the final enacted version. These
provisions included language that would have prohibited all U.S. support to and participation in
the Saudi-led coalition’s military operations against the Houthis in Yemen and provided for a one-
year ban on U.S. sales of precision guided munitions to Saudi Arabia and the United Arab
Emirates, with some exceptions (see Table 1 below).
2020
Saudi Arabia and the Houthis engaged for months during 2020 in negotiations95 over how to
deescalate their conflict, but to the contrary, conflict grew more intense.96 During winter 2020,
amidst the backdrop of fracturing in the anti-Houthi opposition, the Houthis launched a new
offensive into Jawf governorate, where they succeeded in seizing the provincial capital. By April
2020, the Houthis were in position to threaten Marib governorate, one of the last Yemeni areas

93 According to one analysis, “The Houthis have demonstrated that their UAV technology has greatly improved since
the weapons were first introduced to their military arsenal. No other known non-state armed group (NSAG) across the
Middle East/North Africa (MENA) region and beyond has reached the same level of UAV technological
sophistication.” See, Ludovico Carlino, “Houthis Selecting More UAVs Over Ballistic Missiles in Arabian Peninsula
Attacks,” Jane’s Intelligence Weekly, December 6, 2019.

loyal to the Hadi government and where Yemen’s modest oil and gas reserves are located.
Throughout 2020, the Houthis pressed an offensive against Marib, and fighting continued in and
around the northern port of Hudaydah and along an arc from Ta’izz governorate in the southwest
through Bayda, Marib, and Al Jawf governorates.
Evidence of Iranian military support to the Houthis also manifested itself during the year. In
February 2020, the USS Normandy intercepted a small dhow (trading vessel) while on patrol in
the Arabian Sea and discovered a cache of Iranian weapons intended for delivery to Yemen; some
of the items seized included Iranian-made copies of a Russian antitank guided missile, Iranian-
designed and manufactured surface-to-air missiles, and components for unmanned maritime
systems.97 On March 28, 2020, the Houthis fired missiles at the Saudi capital Riyadh (and
elsewhere in the kingdom), and Saudi air defenses reportedly intercepted the projectiles. The
remnants of previous Houthi ballistic missile attacks against Saudi Arabia have proven to
resemble Iran’s Qiam missile, which itself is a modified short-range Scud missile.98
In late April 2020, the STC declared self-administration in southern Yemen, upending a power-
sharing agreement between it and the central Yemeni government signed in November 2019 in
Riyadh. Violent clashes followed the STC’s announcement, and the separatist group seized
hundreds of millions in cash from the central bank in Aden. Saudi Arabia continued to broker
STC-ROYG negotiations. In December 2020, the STC formally joined a unity government with
the ROYG.
At the end of 2020, the Houthis retained control of Hudaydah, the Stockholm agreement
remained unfulfilled, and the United Nations Mission to Support the Hudaydah Agreement
(UNMHA) remained active. Food insecurity was increasing. As of December 2020, there were
4.4 million internally displaced persons (IDPs) in Yemen, among whom 1.7 million were
children. According to the December 2020 United Nations’ Integrated Food Security Phase
Classification (IPC) projections for Yemen, 54% of the population (16.2 million) was seen as
vulnerable to experiencing high levels of acute food insecurity in the first half of 2021. U.N.
projections further estimated 11 million people would likely be in crisis (IPC Phase 3), 5 million
in Emergency (IPC Phase 4), and 47,000 in Catastrophe (IPC Phase 5, famine-like conditions).99
The COVID-19 Pandemic in Yemen
As the COVID-19 pandemic spread throughout Yemen, humanitarian workers accused the Houthis of covering up
the extent of the outbreak in areas under their control.100 Through the end of 2020, officially reported COVID-19
cases were low, as weak testing capacity masked the extent of infections and likely inflated the relative case fatality
rate.101
As the pandemic escalated, United Nations officials called for worldwide humanitarian cease-fires in various
conflict zones in order to respond. On April 8, 2020, Saudi Arabia unilaterally announced a two-week cease-fire in
Yemen and a $500 mil ion pledge of humanitarian aid. At a June 2020 pledging conference hosted by Saudi Arabia,

donors pledged an additional $1.35 bil ion to support assistance programs in Yemen. The U.N.’s $2.4 bil ion appeal
remained underfunded throughout the year, and humanitarian services were scaled back.
International frustration over Houthi obstruction of humanitarian assistance mounted during the
year. Donors and aid implementers warned that if the Houthis would not abide by the principles
of international humanitarian law and allow for unimpeded access for humanitarian assistance,
they would risk losing aid in areas under their control.102 The Trump Administration supported
international attempts to pressure the Houthis to abide by international humanitarian law. On
March 24, 2020, the U.S. Agency for International Development (USAID) initiated a partial
suspension of $50 million in humanitarian programming in Houthi-controlled areas of Yemen,
and maintained its partial suspension during the year due to continued “Houthi-imposed
bureaucratic impediments.” USAID continued to fund more than $13 million in humanitarian
nongovernmental organization activities in northern Yemen for programs that could be conducted
without Houthi interference.
Amid worsening humanitarian conditions and renewed conflict, some Members of Congress
called on the Trump Administration to step up its role in resolving the standoff between the
Houthis and international aid agencies. In February 2020, several Senators wrote a letter to U.S.
Secretary of State Michael Pompeo asking him to take a more active role in “ensuring the
unimpeded, accountable, and impartial flow of assistance and commerce into Yemen.” A month
later, a group of House Members urged Secretary Pompeo to not suspend aid in light of the
COVID-19 pandemic and other humanitarian considerations, concerns about the Houthis
notwithstanding.103
In May 2020, six Senators wrote a letter to Secretary Pompeo and Acting USAID Administrator
Barsa saying “We recognize the challenge that Houthi obstruction poses to relief efforts in
Yemen….We must ensure that development dollars provided to Yemen actually benefit the people
most in need of help, and do not enrich Houthi forces or their partners, who have regularly
imposed unacceptable constraints on common-sense measures to track and account for funds and
supplies.”104 In June 2020, a bipartisan group of Senators wrote a letter to Secretary Pompeo
seeking his leadership in resolving the conflict in Yemen, writing “Your interventions were
important to securing past interim agreements. We now believe that sustained, high-level U.S.
engagement is necessary to finally put an end to this devastating civil war.”105
Analysis
The 115th Congress frequently debated the extent and terms of the United States' involvement in
the ongoing conflict in Yemen. Lawmakers questioned the extent to which successive
Administrations were adhering to existing law related to providing security assistance, including

sales or transfers of defense goods and defense services, while upholding international human
rights standards (e.g., 22 U.S.C. §2754 or 22 U.S.C. §2304). They also enacted new legislation
that would condition or prohibit the use of U.S. funds for some activities related to Yemen and
would extend legislative oversight over the executive branch’s policy toward the war in Yemen.
The House and Senate took different approaches to Yemen at the conclusion of the 115th
Congress. The House and its Rules Committee voted to make resolutions with respect to war
powers and Yemen ineligible for expedited consideration.106 The Senate passed S.J.Res. 54 at the
conclusion of the 115th Congress demonstrating broader opposition in the Senate to U.S.
involvement in the Saudi-led coalition intervention in Yemen relative to previous years. Over
time, the balance of votes shifted in favor of measures that could be described as critical or
restrictive of U.S. support for Saudi-led coalition operations with regard to arms sales, oversight
measures, and war powers measures.
The 116th Congress debated U.S. support for the Saudi-led coalition and Saudi Arabia’s conduct
of the war in Yemen throughout 2019 and 2020. Some Members continued to express dismay at
the humanitarian situation in Yemen and called on relevant parties to implement the Stockholm
Agreement and to establish and maintain a ceasefire. In hearings in both chambers, some
Members raised concerns about the actions of the Saudi-led coalition, highlighting potential end-
use monitoring violations of U.S. weapons provided to the coalition, civilian casualties from
coalition air strikes, and reports of coalition use of child soldiers.
President Trump vetoed bipartisan efforts to remove U.S. forces from hostilities in Yemen
(S.J.Res. 7) and to disapprove of sales of air-to-ground munitions to Saudi Arabia and the United
Arab Emirates (S.J.Res. 36, S.J.Res. 37, and S.J.Res. 38). Both chambers’ passage of the
underlying measures demonstrated continued congressional opposition to aspects of U.S. policy.
In 2020, the House passed an amendment (Amendment 18 in H.Rept. 116-459, considered as part
of H.Amdt. 851) that would have prohibited the use of some FY2021 funds by the State
Department for the transfer of certain munitions and related items and services to Saudi Arabia
and the United Arab Emirates. The provision was not included in the final FY2021 foreign
operations appropriations act (Division K of P.L. 116-260).
Despite the passage of these measures, it remained difficult to identify the locus of congressional
consensus about Yemen. Many in the House and Senate stated that they sought to preserve
cooperative U.S.-Saudi relations in broad terms and expressed concern about Iranian activities in
Yemen, while also expressing support for expanded humanitarian access and efforts to bring the
conflict to a close. Some lawmakers expressed opposition to the Saudi intervention and U.S.
involvement on moral grounds, citing errant coalition air strikes and the prospect of famine and
mass displacement. Others argued that the conflict was creating opportunities for Iran and Sunni
Islamist extremist groups to expand their influence and operations in Yemen. Still others also
referred to factors not directly related to conditions in Yemen, such as the mechanisms and
authorities used by the executive branch to support the coalition and/or anger with the Saudi
government over the 2018 killing of Jamal Khashoggi and other human rights issues, when
discussing continued U.S. support for the coalition’s operations.
Congressional consideration of Yemen legislation during the 115th and 116th Congresses also
typified broader efforts by some Members of Congress to reassert congressional prerogatives
toward U.S. foreign policy and to leverage legislative processes to enhance their effectiveness.
Measures to expand oversight of U.S. support to the Saudi-led coalition and U.S. strategy toward
Yemen received broad bipartisan support, while proponents of other arms sales and war powers

measures used legislative mechanisms to ensure prompt and/or privileged consideration of their
proposals. The volume and frequency of expressions of congressional opposition and the passage
of measures rejecting aspects of the Administration’s policy by majorities in both chambers
appeared to signal constraints on the choices available to the White House and governments in
Riyadh and Abu Dhabi.
In considering the NDAA for 2021 (H.R. 6395), the House endorsed a Yemen-related provision
directing a complete end of U.S. support for Saudi-led coalition airstrike operations, though
House and Senate conferees removed the provision from the final version of the act. As the 116th
Congress drew to a close, Members enacted the NDAA over the President’s veto, including
comprehensive reporting and oversight requirements related to Yemen. The act directed the
Comptroller General to complete a report on all U.S. assistance to the coalition from the start of
the conflict and to examine the relationship between U.S. support to the coalition and civilian
casualties and humanitarian access restrictions.
Congress, the Biden Administration, and Yemen
(2021)
2021
In January 2021, in the final weeks of the Trump Administration, President Trump designated the
Houthis as a Foreign Terrorist Organization (FTO) and a Specially Designated Global Terrorist
(SDGT) entity. In notifying Congress, then-Secretary of State Pompeo asserted that the Houthis
were closely linked to Iran and that the designations were intended to hold the Houthis
accountable for terrorist acts.107 The designations reportedly had been under consideration for
months, and aid organizations had repeatedly cautioned that designations would exacerbate the
humanitarian crisis. On January 19, in concurrence with the FTO designation of the Houthis, the
Department of the Treasury’s Office of Foreign Assets Control (OFAC) issued four general
licenses to allow humanitarian assistance and other commodities to reach Yemen even if a
transaction involved the Houthis.
Congressional reactions to President Trump’s actions in the final days of his Administration were
mixed. Some Members wished to see the United States continue its maximum pressure campaign
on Iran and viewed the Houthi designation as part of that effort, while other Members called on
the Biden Administration to reverse the designations. The terrorist designations of the Houthis
also drew bipartisan congressional concern over their timing, efficacy, potential harm to any
peace process, and possible humanitarian impact.108
After President Biden took office, one of his first foreign policy priorities was to review the
previous administration’s recent actions on Yemen. On January 25, OFAC issued a new general
license exempting nearly all transactions with the Houthis from sanctions restrictions until
February 26, 2021, while the Yemen sanctions policy was reviewed.109

On February 4, 2021, President Biden announced that his Administration would increase U.S.
efforts to resolve the conflict in Yemen by (1) appointing a special envoy to Yemen; (2) ending
U.S. support for offensive operations in the war, including relevant arms sales; and (3) continuing
to help Saudi Arabia defend its territory from Houthi attacks. A week later, Secretary of State
Antony Blinken revoked the FTO and SDGT designations of the Houthis stating, “We have
listened to warnings from the United Nations, humanitarian groups, and bipartisan members of
Congress, among others, that the designations could have a devastating impact on Yemenis’
access to basic commodities like food and fuel.”110 The Secretary retained the designations of
three Houthi individuals as Specially Designated Nationals (SDN) under Executive Order (E.O.)
13611.111 President Obama issued that order in 2012 to block property of persons threatening the
peace, security, or stability of Yemen. On March 2, the Biden Administration designated two
additional Houthi leaders under E.O. 13611.112
Military Developments. In February 2021, the Houthis resumed their offensive against Marib.113
That offensive intensified in the fall of 2021, expanding to new fronts in parts of southern Yemen,
as the Houthis sought to cut off ROYG reinforcement of Marib. Houthi fighters attacked in waves
and used unmanned aerial vehicles to target ROYG fortifications. According to one report, as of
October 1, 2021, 1,700 government troops in Marib province had been killed and around 7,000
wounded.114 The Houthis endured high casualties as well as they made gains toward Marib city,
as Saudi air strikes targeted Houthi fighters advancing over open ground.115 In late 2021, Yemeni
forces backed by the UAE made advances against Houthi forces, recapturing the governorate of
Shabwa and severing some Houthi resupply lines to Marib.116 Nevertheless, as of December 2021
the Houthis controlled or contested most of northern Yemen, including the country’s three largest
cities (Sana’a, Taiz, and Al Hudaydah).
Peace Process. Throughout 2021, U.S. Special Envoy Lenderking engaged in talks with key
parties to the conflict through an ongoing series of visits to Saudi Arabia, Oman, and other
regional countries. In March 2021, Saudi Arabia offered a nationwide ceasefire117 that Lenderking
praised.118 The Houthis almost immediately dismissed the Saudi proposal as “nothing new” and
reiterated their demands for the Saudis unilaterally to lift their blockade of Sana’a airport and
Hudaydah port.119

Congress and the War in Yemen: Oversight and Legislation 2015-2021

By summer 2021, the Biden Administration had become more openly critical of the Houthis for
rejecting repeated attempts at brokering a cease-fire while continuing their ground offensive in
Yemen and their aerial assaults against civilian targets inside Saudi Arabia. According to State
Department spokesperson Ned Price
When it comes to Yemen, you asked if we are fed up with the Houthi attacks. The answer
to that is yes. We are beyond fed up. We are horrified by the repeated attacks on Marib.
We strongly condemn the Houthi missile attack on a residential neighborhood in Marib on
June 29th. It took civilian lives, including the life of a child. We believe it is long past time
to end the conflict in Yemen and to provide immediate relief to the Yemeni people.120
Several months later, U.S. Deputy Representative to the United Nations Ambassador Richard
Mills spoke before the Security Council, where he reiterated the Biden Administration’s view that
the Houthis were obstructing the peace process. According to Ambassador Mills,
In 2021 alone, the Houthis have launched more than 240 attacks into Saudi Arabia,
endangering civilians throughout the country, including the 70,000 American citizens who
reside there.121
Through the end of 2021, the Houthis continued to demand that the coalition agree to lift
restrictions on access to airports and ports in northern Yemen prior to any ceasefire agreement.122
Iranian Influence. Throughout 2021, the Biden Administration continued the policy of
successive administrations to attempt to thwart Iranian assistance to the Houthis. In May 2021,
the USS Monterey seized hundreds of smuggled weapons inside a stateless dhow (fishing boat) in
the Arabian Sea. U.S. officials noted that the illicit shipment originated in Iran and was most
likely bound for the Houthis.123 In December 2021, the U.S. Navy seized 1,400 assault rifles from
a vessel originating in Iran; U.S. officials stated that the ship was “on a route historically used to
illegally smuggle weapons to the Houthis in Yemen.”124 In another line of effort to curb Iranian
influence in Yemen, on June 10, 2021, under the authority of Executive Order 13224, OFAC
designated several members of a smuggling network that “helps fund Iran’s Islamic
Revolutionary Guard Corps-Qods Force (IRGC-QF) and the Houthis in Yemen.”125 This
designation came several weeks after the Biden Administration, pursuant to Executive Order
13611, designated two senior Houthis leaders as SDNs for their role in the offensive against
Marib.126
U.S. Ceases Support for Offensive Operations. Since the President’s February 2021 policy
pronouncement on Yemen, the United States has ceased support to offensive operations by Saudi
Arabia and its coalition partners and made some changes to U.S. missile and air defense posture

in Saudi Arabia. In April 2021, CENTCOM Commander General Kenneth F. McKenzie, Jr. told
one reporter that in Marib, “We’re not doing anything in terms of ISR (intelligence, surveillance
and reconnaissance) … on things happening in Marib or places like that.”127 Nevertheless,
Administration officials have reiterated U.S. support for Saudi Arabia’s territorial defense. In
testimony before the House Armed Services Committee, Amanda Dory, Acting Under Secretary
of Defense for Policy, stated:
Our second line of effort is to provide limited, non-combat support to the Saudi-led
Coalition (SLC) focused on defending Saudi Arabia from external threats. This non-
combat support is consistent with President Biden’s February 4, 2021 announcement to
increase U.S. diplomatic efforts to end the war in Yemen and cease U.S. support to SLC
offensive operations in Yemen. Continued U.S. assistance is designed to reassure U.S.
partners of our commitment to their defense so that they can meaningfully engage in the
United Nations political process to end the war. In support of the President’s policy,
roughly 60 DoD military advisors are deployed to help Saudi Arabia’s Armed Forces
defend their territory from threats emanating from Yemen.128
In December 2021, a U.S. official stated, “our support for the Saudi-led offensive operations in
Yemen, it ended in February, including relevant arms sales. We have suspended, as you know,
proposed sales of certain air-to-ground munitions, but we are committed to continuing to provide
[...] support to Saudi Arabia to improve its ability to defend its territory.”129 Administration
officials the same month opposed proposals in Congress to block the sale of advanced medium
range air-to-air missiles to Saudi Arabia (S.J.Res. 31/H.J.Res. 63 ), stating that, “Saudi Arabia
uses these munitions to defend against aerial cross-border attacks, such as Houthi explosive-laden
drones.”130
Humanitarian Aid. Throughout 2021, the United States remained the top single donor of
humanitarian assistance for Yemen. In FY2021, the United States contributed $805.8 million
toward the crisis, bringing total U.S. contributions to nearly $3.9 billion since the start of the
crisis in 2014/2015. U.S. officials have called for restrictions on fuel imports through Hudaydah
port to be “lifted immediately” and for Sana’a airport to be “opened and operational.”131
Congressional Action. In 2021, the crisis in Yemen has not been as prominent a matter before
Congress as in previous years, when Congress considered and voted on war powers
authorizations and possible emergency arms sales to Saudi Arabia, the United Arab Emirates, and
others. During the 117th Congress, as Table 1 below indicates, Yemen has featured in
consideration of the 2022 National Defense Authorization Act (S. 1605/H.R. 4350). Provisions
related to Yemen also are contained in House versions of the FY2022 foreign operations and
defense appropriations bills (H.R. 4373 and H.R. 4432).
One issue regarding Yemen that has received some bipartisan attention is the continued Saudi-led
coalition restriction of access to some Yemeni ports. In April 2021, House Foreign Affairs Middle
East, North Africa, and Global Counterterrorism Subcommittee Chair Ted Deutch and Ranking
Member Joe Wilson sent a letter to Secretary Blinken seeking U.S. support in ending the Saudi-

led coalition’s “continued obstruction of commercial and humanitarian imports to Yemen.”132 In
the Senate, Democrats sent a similar letter to the President, seeking his support in demanding
“that Saudi Arabia allow the unfettered delivery of food, fuel, and other humanitarian aid through
the Hodeidah port, under United Nations auspices to deliver humanitarian assistance to the
Yemeni people.”133
Analysis
The Biden Administration has made a number of changes in U.S. Yemen policy designed to
emphasize its peacemaking role and prioritize efforts to resolve the humanitarian crisis.134
Nevertheless, the Houthis have escalated their attacks in Yemen and across the border against
Saudi Arabia and the United Arab Emirates since February 2021, perhaps in an effort to maximize
their territorial gains and their leverage amid renewed international efforts, including by the
Biden Administration, to broker a cease-fire to the conflict.
Saudi Arabia’s intervention using air power in 2021 focused on supporting ROYG ground forces
in Marib and, combined with other coalition support to the ROYG, appeared pivotal to the
outcome of fighting there. The Administration has not described publicly the extent of any Saudi-
U.S. understandings over what type of coalition operations in Yemen constitute defensive versus
offensive air strikes. U.S. officials demanded a halt to the Houthi offensive in Marib, but the
Administration did not indicate what specific military, advisory, or assistance steps, if any, it was
willing to take to attempt to ensure that outcome or compel the parties involved. Saudi Arabia
offered ceasefire terms to the Houthis and continues to engage U.S. and other international parties
in peace talks, but ongoing Houthi cross-border attacks pose what Saudi and Emirati officials
regard as an unacceptable threat to their country. Saudi Arabia and its partners may continue to
seek to disrupt weapons transfers and support from Iran and Iran-backed groups to the Houthis.
Reports of errant Saudi air strikes that have resulted in civilian casualties continued in 2021,
though less frequently than in earlier periods of the war. While the Houthis do not possess
manned aircraft, they conducted mortar, missile, rocket, and unmanned drone attacks against their
Yemeni adversaries and against Saudi territory, the latter of which they described as a response to
the Saudi-led coalition’s maritime blockade of Yemen’s west coast and closure of Sana’a airport.
According to the Yemen Data Project, a nongovernmental organization that compiles public
reporting about the conflict in Yemen, Saudi and coalition airstrikes nearly doubled in volume
during 2020 relative to 2019, and continued near 2020 levels through 2021, with nearly half
occurring in and around Marib. Overall civilian casualties in the conflict were highest in 2015,
and continued to occur in connection with indiscriminate fire by Houthi forces, shelling by
government of Yemen and allied local forces, and, to a less frequent extent than in the early years
of the conflict, Saudi and coalition airstrikes.135
The Administration’s 2021 decision to withdraw U.S. missile and air defense assets from Saudi
territory was coordinated with Saudi officials, who said it was “carried out through common

understanding and realignment of defense strategies.”136 Saudi defense officials have stated that
Saudi military capabilities are sufficient to defend the kingdom’s territory, but press reports
suggest that the frequency and volume of Houthi attacks are straining the kingdom’s defenses.137
Saudi Arabia has welcomed additional missile defense support from U.S.-ally Greece, and the
Biden Administration has approved the sale and transfer of Patriot missiles to Saudi Arabia by
other U.S. allies and partners.138
As noted above, the conflict in Yemen has generally not been a major foreign policy issue of
congressional consideration in the 117th Congress, but amendments considered and adopted to the
House version of the 2022 NDAA and provisions of the final version of the act reflect continued
concern about the conflict and U.S. policy toward it. The final version of the act extends a ban on
U.S. refueling of Saudi coalition aircraft and requires reporting on Saudi offensive airstrikes in
Yemen resulting civilian casualties and the aircraft and munitions used in such strikes. It does not
include other restrictive provisions endorsed by the House in its version of the bill. The Senate
voted in December 2021 against advancing a measure to block the sale of certain air-to-air
munitions to Saudi Arabia, with some Senators highlighting Houthi cross border attacks during
floor debate (S.J.Res. 31, Table 1).139
Congress has allocated funds in recent foreign operations appropriations acts for stabilization
purposes in Yemen and could consider additional requests from the Administration if mediation
efforts produce a durable ceasefire and allow for stabilization operations to expand while intra-
Yemeni political negotiations resume. Questions about the delivery of assistance in areas
remaining under Houthi control are likely to remain relevant, including in the context of the
potential re-imposition of terrorism sanctions on the Houthis as a group.
In light of the Houthis’ cross-border attacks on Saudi Arabia, their offensive operations against
Yemeni rivals, and Saudi and coalition counter-operations, Congress also may continue to debate
the extent to which U.S. support to Saudi and Saudi-led coalition operations in Yemen should be
conditioned or restricted by law. In light of expressed views in Congress and congressional voting
patterns, unilateral escalation of the conflict by the coalition or coalition operations resulting in
increased civilian casualties or harm could potentially generate additional opposition to U.S.
involvement among Members. This might lead Congress to attempt to assert more influence over
executive branch decisions and possibly override presidential preferences. Debate to date also
suggests that, similarly, escalation attributable to the Houthis, closer overt coordination between
the Houthis and Iran, and/or Houthi rejection of United Nations resolution efforts may lead some
Members to support continued or more expansive U.S. cooperation with the coalition. Houthi
successes on the battlefield could complicate congressional considerations on issues of legislative
relevance, such as security assistance and humanitarian aid.
Looking ahead, lawmakers might broaden the scope of their oversight activities beyond the
current conflict to address Yemen’s chronic instability more fully. They also might focus on
challenges to the delivery of humanitarian assistance, counterterrorism threats, or prospects for
broader U.S. security cooperation with ROYG forces. Yemen has been devastated by years of
war: at the start of 2022, U.N. officials described it as one of the world’s worst humanitarian

crises.140 Experts expect Yemen to require sustained international attention and financial
assistance in order to help local actors reach and sustain a political settlement. Thus, Congress
may grapple with Yemen-related questions about the conduct of U.S. diplomacy, the provision of
U.S. security support, and the investment of U.S. assistance and defense funds for years to come.
