The Senate approved the repeal of strict sanctions legislation targeting the now-deposed Assad regime in Syria, as part of its version of the 2026 National Defense Authorization Act.

Lawmakers on both sides of the aisle have been working to repeal or roll back the sanctions, known as the Caesar Act, for several months, though the effort is not without some opponents.

The chamber also passed, as part of a bipartisan package of amendments, an amendment led by Sens. Lindsey Graham (R-SC) and Chris Van Hollen (D-MD) — opposed by some Syrian-American activists — that requires regular reports to Congress certifying Syria’s compliance with a variety of U.S. priorities and urges the administration to reimpose sanctions if such verification cannot be completed.

The House version of the NDAA does not include a similar provision, so whether the sanctions repeal is included in the final bill, and in what form, will be subject to negotiations between the two chambers. Legislation placing a variety of conditions on the suspension of the Caesar Act, rather than repealing the sanctions, has gained momentum in the House.

The Senate also approved, by voice vote, an amendment that would repeal the Authorizations for Use of Military Force that allowed for the Iraq and Gulf wars. With similar provisions included in the House version of the bill, the repeal of those war authorizations, a long-term goal of lawmakers on both sides of the aisle, looks increasingly likely this year.

Opponents have argued that the process has moved too quickly and with too little deliberation and consultation with the administration, and that repealing the authorities could jeopardize counterterrorism operations.

The upper chamber rejected an amendment that would have barred the modification of a Qatari-donated jumbo jet to serve as Air Force One, by a party-line vote of 50 to 46.

Other provisions added to the legislation in bipartisan amendment packages include programs aimed at countering foreign information manipulation and interference by adversaries like Iran; a study of the potential security conditions for reopening the U.S. embassy in Damascus, Syria; and legislation aimed at countering the wrongful detentions of U.S. citizens by adversaries like Iran by creating a new designation and penalties for countries engaging in such activity.

The legislation also expands and modifies various U.S.-Israel cooperative military programs.

The House passed its version of the 2026 National Defense Authorization Act on Wednesday, including an amendment that would repeal the Authorizations for Use of Military Force that allowed for the Iraq war and the Gulf War.

The House also passed a series of amendments aimed at countering the Boycott, Divestment and Sanctions movement targeting Israel and enhancing defense cooperation with Israel.

An effort to repeal the Authorization for Use of Military Force passed by a bipartisan 261-167 vote, with 49 Republicans voting with 212 Democrats in favor of the amendment.

Rep. Brian Mast (R-FL), the chair of the House Foreign Affairs Committee, said he agreed that there should be sunsets on AUMFs, but said that changes should not be made without discussions with key U.S. military leaders about how the repeal would impact U.S. activities and counterterrorism efforts and whether additional authorities would be needed to re-authorize ongoing U.S. operations.

“These are questions that were not asked, and the answers were not given,” Mast said. “We have, I think, probably large agreement on reasons to sunset things, but it should not be done in absence of doing something of this gravity in the proper way.”

Rep. Greg Meeks (D-NY), the ranking member of the Foreign Affairs Committee, said that the AUMFs are “long obsolete” and that keeping them effective “only risk[s] abuse by administrations of either party to sanction military force that Congress has not consented or approved.” 

He said he’s committed to ensuring that the provision remains in the final version of the NDAA agreed to in negotiation with the Senate.

Repeal efforts for the AUMFs have seen substantial momentum in recent previous years.

Other amendments approved by voice votes as part of broader amendment packages aimed to counter international targeting of Israel, including banning the Defense Department from contracting with entities boycotting Israel, instructing the administration to monitor the impact of global arms embargoes, and other sanctions imposed on Israel, and determine how the U.S. can mitigate such issues. They also urged the administration to engage with allies to ensure they do not enforce International Criminal Court arrest warrants against Israeli officials and called on the Pentagon not to participate in defense exhibitions that exclude Israel.

To further reinforce U.S.-Israel defensive cooperation, other amendments would order the creation of a Defense Innovation Unit field office in Israel to engage with the government and private sector there on technological development and mandate that the U.S. and Israel study the possibility of integrating Israel into the U.S. defense industrial base.

Additionally, the House added requirements that the Pentagon report to Congress on the status of integrated air and missile defense cooperation in the Middle East, including lessons learned from recent attacks in the region; on joint U.S.-Israel efforts to increase production of Arrow missile defense interceptors, stockpiles of which were significantly depleted during the Israel-Iran war, including whether further authorizations or funding are needed; on U.S.-Israel joint military exercises, the missions rehearsed and how regional partners can be invited to join; and on the status of pending deliveries of military aircraft and air-launched munitions, including the reasons for any delays and how they can be resolved.

Other amendments would require the U.S, Egypt and Israel to study steps that they can take to block smuggling into Gaza from tunnels in Egypt or via the Mediterranean Sea and the Pentagon to report to Congress on the U.S.-Bahrain partnership agreement and possibilities for expanding it to include other regional allies.

Additional amendments seek to support Iranian dissidents and counter the Iranian regime: requiring a strategy on encouraging and enticing top Iranian officials to defect; requiring the Pentagon to help develop technologies to counter internet blockages imposed by Iran and other adversaries; requiring a strategy to counter Iran and Hezbollah’s operations in South America; and expanding reporting requirements regarding Iran’s terrorism strategy, proxies, relationship with Russia, supply chains and weapons production capabilities.

Another amendment would require the Pentagon to quickly release all files on the Iranian proxy attack on the Tower 22 facility in Jordan that killed U.S. service members in January 2024.

An additional amendment would award a medal to servicemembers involved in the U.S. strikes on Iran’s nuclear facilities.

Two amendments by Rep. Marjorie Taylor Greene (R-GA), which aimed to block U.S. support for Ukraine and Taiwan, were resoundingly defeated 372-60 and 422-9, respectively. An amendment proposed by Greene to strip out programs supporting Israel from the bill did not receive consideration or a vote on the floor.

Greene made similar efforts to block funding for Israel, Ukraine and Taiwan during consideration earlier this year of 2026 Pentagon funding, which were defeated along similar lines.

The amended NDAA passed the House by a 231-196 vote, with just 17 Democrats voting for the bill as most voiced objections to provisions relating to transgender medical care and renewable energy, among other issues. The Senate is considering its own version of the NDAA this week as well.
Among a slew of other issues, a series of proposed amendments aimed at cracking down on Turkey were not approved for consideration on the House floor.

Bipartisan groups of House and Senate members have introduced legislation to repeal the Caesar Syria Civilian Protection Act, sanctions legislation passed in 2019 targeting the former Syrian government led by Bashar al-Assad, a step that proponents say will help remove obstacles to reconstruction and stabilization efforts in post-Assad Syria.

The administration recently announced that it would be lifting all sanctions on Syria, but the Caesar Act sanctions can only be temporarily waived, for periods of 180 days, barring a full repeal by Congress. Administration officials have indicated that they’d support such a step, and sanctions relief, in principle, has broad support on both sides of the aisle.

The sanctions, named for a pseudonymous individual who documented the Assad regime’s torture of civilians, also targeted Syrian critical industries, individuals and businesses that supported or did business with the Syrian government and Iranian and Russian entities that supported the Syrian government. 

Sens. Jeanne Shaheen (D-NH) and Rand Paul (R-KY) introduced legislation on Wednesday to repeal the sanctions. 

Reps. Joe Wilson (R-SC), Jimmy Panetta (D-CA), Marlin Stutzman (R-IN), Lou Correa (D-CA), Jack Bergman (R-MI), Pramila Jayapal (D-WA), Anna Paulina Luna (R-FL) and Mike Levin (D-CA) introduced a similar bill in the House last week.

“We can keep the new Syrian authorities accountable without decimating the economy,” Shaheen said in a statement. “Sustained diplomatic engagement can yield tremendous results.”

Paul argued against the Caesar Act sanctions in principle, saying they had been too broadly targeted.

“While the Caesar Act was intended to isolate the Assad regime, it has ended up punishing everyday Syrians — fueling poverty, crippling recovery, and blocking progress toward peace,” Paul said. “This repeal is about restoring a more targeted, principled approach that holds bad actors accountable without inflicting unnecessary suffering on the very people we claim to support.”

The timeline for the repeal effort is somewhat unclear: Secretary of State Marco Rubio testified in May that the administration’s ultimate goal would be to repeal the act, conditioned on the new Syrian government “mak[ing] enough progress” on U.S. priority issues. 

But U.S. Ambassador to Turkey Tom Barrack, who also serves as U.S. envoy to Syria, indicated greater urgency, calling for Congress to repeal the sanctions within the first 180-day waiver period, which is renewable if the sanctions are not repealed before then.

“I promise you the one person who has less patience with these sanctions than all of you is President Trump,” Barrack said during a visit to Syria to meet with President Ahmad al-Sharaa last month.

The House lawmakers leading the repeal legislation represent a broad spectrum of the House,  ranging from a former chair of the House Progressive Caucus to a former House Freedom Caucus member, and including Israel hawks on both sides of the aisle.

“The Assad regime sanctioned by the Caesar Act no longer exists, and it is time to repeal the law to provide long-term certainty to those who would like to invest in the reconstruction and rebuilding of Syria,” Wilson said in a statement.

Panetta said that repealing the sanctions would help the U.S. “position itself as a partner for continued progress” as adversaries aim to gain a foothold in Syria.

“The repeal of these broad sanctions will give foreign partners the certainty they need to invest in the Syrian economy and give their new government a chance to succeed,” Jayapal said.
