Four Republican members of the US House of Representatives broke with President Donald Trump on Thursday, joining Democrats to pass a war powers resolution disapproving of American military action against Iran. The vote is a notable rebuke of Trump's Iran policy from within his own party, though it carries mostly symbolic and political weight rather than an immediate legal halt to operations, given the broader constitutional and practical constraints on such resolutions.

Democratic Representatives Jason Crow of Colorado and Pramila Jayapal of Washington forced the vote using a "privileged resolution", a procedural mechanism that lets rank-and-file members bring legislation to the floor even against the wishes of House Republican leadership. The resolution passed 214-208, with voting largely along party lines except for the four Republican defectors, and it calls for halting military conflict against Iran unless Congress explicitly authorises it.
