The House narrowly voted on Thursday to restrict President Donald Trump’s war powers in Iran for a second time, with four Republicans breaking ranks with their party to push the concurrent resolution over the line in a 214-208 vote, according to congressional records. The measure calls for a halt to any military action in Iran without congressional approval. While largely symbolic—as it would not go to the president’s desk or carry the force of law even if passed by the Senate—the vote highlights sustained legislative opposition to the ongoing conflict from within the Republican Party.
The legislative rebuke coincides with the completion of the United States’ twelfth consecutive night of military strikes against Iran. The renewed aerial campaign follows the breakdown of a cease-fire earlier this month, after which attacks resumed from both sides.
The four House Republicans who crossed party lines to support the resolution on Thursday were Representatives Thomas Massie of Kentucky, Brian Fitzpatrick of Pennsylvania, Tom Barrett of Michigan, and Warren Davidson of Ohio. The vast majority of their GOP colleagues voted against the measure, echoing resistance seen during previous legislative attempts to curb the executive branch’s military authority.
Democratic Representative Pramila Jayapal of Washington, who led the resolution, spoke on the House floor to emphasize the gravity of the vote. Calling the measure an act of conscience, she stated that lawmakers must find the strength to do what is right for the American people and send the clearest message that the House of Representatives is reasserting its authority over war.
Shifting Stances Among GOP Lawmakers
Representative Thomas Massie has maintained a consistent stance, voting in favor of every Iran war powers resolution brought before the House. Following Thursday’s vote, Massie wrote on X that American service members are dying while gas and fertilizer prices soar, asserting that it is time to end the war.
Other defectors have adjusted their approaches over the course of the conflict. Representative Brian Fitzpatrick initially opposed a restriction measure in March, labeling it overbroad, but later introduced his own proposal for a phased-out troop withdrawal. By May, after the expiration of the 60-day deadline established under the War Powers Resolution of 1973 for unauthorized military hostilities, Fitzpatrick voted to restrict presidential war powers, stating that the law must be followed.
Representative Tom Barrett similarly backed the early stages of the conflict, praising the administration’s initial actions and arguing that the president had earned the opportunity to resolve the situation quickly. By May, however, Barrett introduced an Authorization for Use of Military Force to establish a 90-day deadline for finishing campaign objectives, warning that the United States must avoid another endless war. Representative Warren Davidson, a former U.S. Army Ranger, has recorded a more mixed voting record on specific resolutions but maintains on his official website that the Constitution places the solemn responsibility of authorizing military action directly with Congress.
Senate Actions and Executive Pushback
In the upper chamber, the Senate rejected multiple similar measures on Thursday in a 49-47 vote. Senator Susan Collins of Maine stood as the sole Republican to join Democrats in voting to advance the resolution. Collins pointed to the strict requirements of the 1973 War Powers Act, stating in an April statement that its 60-day deadline for congressional authorization or withdrawal is a requirement rather than a suggestion.
Other Senate Republicans have navigated similar political terrain. Senator Rand Paul has consistently supported war powers restrictions—with the exception of one vote cast as “present” to provide space for peace negotiations—arguing that the conflict should never have begun without explicit congressional permission. Senator Lisa Murkowski of Alaska expressed early concerns that the president should have sought congressional approval before initiating large-scale strikes, though she previously cautioned against abrupt cessations of offensive operations that might leave deployed personnel vulnerable.
Senator Bill Cassidy of Louisiana expressed frustration in May that Congress had been left in the dark regarding war objectives and later voted in favor of a war powers resolution in June. However, following pressure from the administration and after receiving briefings on a planned operational path, Cassidy voted against advancing the measure on Thursday.
President Trump has sharply criticized lawmakers supporting these constraints, previously labeling House resolutions meaningless and unpatriotic while directing pointed remarks at Republican senators who backed upper-chamber measures. With the Senate having turned back Thursday’s latest vehicle, the legislative debate over the boundaries of executive war authority remains sharply contested ahead of the next scheduled congressional sessions.
