The House of Representatives passed a war powers resolution Wednesday that seeks to curb President Donald Trump's authority to conduct military operations against Iran.

The measure passed 215-208, with four Republicans joining all Democrats in support. The resolution directs the president to end the use of U.S. armed forces in hostilities with Iran unless Congress specifically authorizes such action.

The vote marks the first time the House has approved such a resolution since the start of the three-month conflict. Republican lawmakers Thomas Massie of Kentucky, Brian Fitzpatrick of Pennsylvania, Tom Barrett of Michigan, and Warren Davidson of Ohio crossed party lines to back the measure.

The resolution is largely symbolic. It would still require Senate approval and faces an expected veto from Trump, who has asserted broad commander-in-chief powers. Even if enacted, the measure would not immediately force a withdrawal of U.S. forces.

Democratic leaders framed the vote as a necessary check on executive power amid an unpopular military campaign. Republican opponents argued it undermines the president's negotiating position and weakens U.S. leverage in the region.

The House action follows similar efforts in the Senate earlier this year, where a related measure advanced with some Republican support. The ongoing conflict has involved U.S. strikes on Iranian targets in response to attacks on American interests and allies.

GOP leaders had previously delayed consideration of the resolution in May to avoid a defeat, but the measure reached the floor this week after procedural maneuvering by Democrats.

The passage highlights growing congressional frustration with the protracted engagement, even as the administration maintains that military pressure is essential to deter Iranian aggression and protect U.S. forces.
