The US House of Representatives has voted to curb President Donald Trump’s authority to wage war against Iran, approving a resolution that demands the withdrawal of American forces from hostilities without explicit congressional approval. The measure passed 214-208, with four Republicans joining Democrats in a rare bipartisan rebuke of the administration’s military strategy.

What the resolution demands

The war powers resolution, introduced by Democratic Representative Pramila Jayapal of Washington, directs the president to "remove the use of United States Armed Forces from hostilities against the Islamic Republic of Iran or any part of its government or military." This includes ground troops in combat roles or occupation scenarios, unless Congress explicitly authorises such action. The vote comes as tensions escalate in the region, with US service members killed in recent Iranian attacks and no clear diplomatic off-ramp in sight.

Under the War Powers Resolution of 1973, the president must notify Congress within 48 hours of initiating military hostilities and limit operations to 60 days unless lawmakers approve an extension. The Trump administration has argued that hostilities "terminated" following a ceasefire in April, restarting the statutory clock—though attacks have continued on both sides. Critics, including Jayapal and Colorado Democrat Jason Crow, contend the administration is exploiting legal loopholes to bypass congressional oversight.

Bipartisan defiance and political stakes

Four House Republicans—Tom Barrett of Michigan, Brian Fitzpatrick of Pennsylvania, Warren Davidson of Ohio, and Thomas Massie of Kentucky—broke ranks to support the resolution. Their votes underscore growing unease within the GOP over the war’s trajectory, though most Republicans remain aligned with the president. Trump has dismissed concerns about political fallout ahead of the midterm elections, while Democrats warn of constitutional overreach.

House Republicans, meanwhile, advanced a separate proposal to allocate up to $73 billion in funding for the Iran conflict and $12 billion in agricultural aid to offset economic damage. The measure, opposed by two Republicans and one independent, faces significant hurdles in the Senate, where a similar war powers resolution failed to advance later on Thursday.

What happens next

The administration has requested $67 billion in supplemental funding for the war and $1.5 trillion for the Pentagon’s next fiscal year. Democrats are exploring legal avenues to enforce the resolution and may leverage their influence over the appropriations process to block additional funding. With no immediate end to the conflict in sight, the standoff between Congress and the White House over war powers is set to intensify.
