The House of Representatives passed a war powers resolution directing President Trump to halt military action against Iran, marking the first time such a measure has cleared the chamber and representing a notable bipartisan rebuke of the administration's military posture toward Tehran.

The resolution passed with support from a bloc of Republican lawmakers who crossed the aisle to join Democrats, underscoring growing unease within the president's own party over the scope and legal authority of the strikes against Iran. The vote signals that opposition to unilateral executive military action has reached a threshold capable of producing a congressional majority.

War powers resolutions invoke the 1973 War Powers Resolution, which requires the president to notify Congress within 48 hours of committing armed forces to hostilities and limits unauthorized military engagements to 60 days without congressional approval. The White House has not publicly indicated whether it will comply with the resolution or veto it if it advances through the Senate.

The measure now faces an uncertain path in the Senate, where the administration may have more support. Passage in the House nonetheless carries symbolic and political weight, putting lawmakers on record regarding the legal basis for the Iran strikes and increasing pressure on the administration to seek formal congressional authorization if military operations continue.
