The US House of Representatives voted on June 3, 2026, to curtail President Trump’s authority to wage war against Iran without explicit congressional sign-off. The final tally was 215-208, a razor-thin margin that required four Republican defectors to push the resolution over the finish line.
The measure invokes constitutional war powers provisions that demand the president obtain authorization from Congress before continuing military hostilities.
The vote and the defectors
The four Republicans who broke ranks tell an interesting story about the ideological fault lines within the party. Brian Fitzpatrick of Pennsylvania, Thomas Massie of Kentucky, Tom Barrett of Michigan, and Warren Davidson of Ohio all voted with every single Democrat in the chamber.
Massie and Davidson are well-known libertarian-leaning members who have historically been skeptical of executive overreach on military matters. Fitzpatrick has long positioned himself as one of the most moderate Republicans in the House.
