The House passed a resolution directing President Trump to end military operations in Iran on Thursday, but the Senate blocked a similar measure hours later, underscoring a deepening split in Congress over the escalating conflict. The House voted 214-208 to approve the war powers resolution, with four Republicans joining Democrats in the rebuke, while the Senate voted 49-47 to block its own version, marking a striking reversal from a bipartisan breakthrough just four weeks earlier.
The House resolution, introduced by Representative Pramila Jayapal of Washington, directs Trump to halt U.S. military action against Iran unless Congress authorizes it. Four Republicans—Tom Barrett of Michigan, Brian Fitzpatrick of Pennsylvania, Warren Davidson of Ohio, and Thomas Massie of Kentucky—crossed party lines to support the measure alongside Democrats.
In the Senate procedural vote, Republican Susan Collins of Maine joined Democrats in favor, while Democrat John Fetterman of Pennsylvania voted with Republicans to block the resolution. Four Republican senators did not vote. The outcome stands in stark contrast to June 23, when the Senate passed a war powers resolution 50-48 for the first time in the conflict’s history, with four Republicans—Bill Cassidy of Louisiana, Susan Collins, Lisa Murkowski of Alaska, and Mitt Romney of Utah—voting with Democrats.
The War Powers Resolution of 1973 requires presidents to notify Congress within 48 hours of committing armed forces to military action and forbids armed forces from remaining engaged for more than 60 days without congressional approval. Though the resolutions passed by Congress are largely symbolic and do not carry the force of law, they represent rare expressions of congressional frustration with Trump’s military strategy. Trump has continued military operations despite the June resolution, resuming strikes in early July after a brief ceasefire collapsed.
The votes reflect growing concern among lawmakers about the conflict, which Trump initially characterized as a swift, focused operation but has instead stretched into months of sustained military engagement. Jayapal told reporters after the House vote that the measure transcends partisan divisions. “This is not a partisan issue. Vast majorities of Americans, of all parties, believe that this is an unconstitutional and illegal war that needs to stop,” she said, citing troop deaths, civilian casualties, and rising fuel costs as consequences of the conflict.
The Senate’s decision to block the resolution hours after the House passed it underscores the narrow Republican majorities in both chambers and the deep divisions over war strategy ahead of November’s midterm elections. Democrats are seeking to link the unpopular Iran war with broader affordability concerns as they campaign to retain control of Congress, while Republicans argue that undermining the president during wartime weakens the nation’s negotiating position.
The Constitution grants Congress, not the president, the power to declare war and authorize military force. However, presidents have long ordered short-term military operations to counter immediate threats without seeking prior congressional approval, a practice that has persisted despite decades of debate over the War Powers Resolution’s enforceability.
The House also passed a $1.15 trillion defense bill in a narrow 216-212 vote on July 22, allocating substantial resources toward the Iran war effort even as lawmakers remained divided over its legitimacy. The Senate’s blocking of the war powers resolution suggests that Republicans retain enough votes to sustain Trump’s military operations without congressional constraint, at least for now.
