The US House of Representatives has voted 220-204 to approve a war powers resolution aimed at halting President Donald Trump's ability to continue military action against Iran without congressional approval, with a small number of Republicans joining all Democrats. It is the latest in a series of similar votes this summer, though none of the resolutions have reached Trump's desk, where a veto would be all but certain, meaning the measure is largely symbolic but underscores growing unease within his own party over the unresolved conflict.

The resolution invokes the War Powers Resolution of 1973 and would require US forces to be withdrawn from further hostilities against Iran unless Congress explicitly authorises continued action, with exceptions for defending America or its allies from an imminent attack. The vote followed nearly seven months of intermittent, deadly missile exchanges since Trump launched the campaign on 28 February, and came shortly after Republican Rep. Thomas Massie read out articles of impeachment against War Secretary Pete Hegseth, accusing him of unlawfully continuing military action without proper authorisation. Democrat Seth Moulton criticised Trump's earlier claim the war would last only weeks, while Republican Brian Mast defended the administration's stance, arguing Iran remains a persistent threat. The vote, likely the House's last on the issue before the midterms, highlights how the prolonged conflict is becoming a significant campaign issue.
