Four House Republicans joined nearly all Democrats on June 3, 2026, to vote in favor of a resolution aimed at removing U.S. Armed Forces from hostilities with Iran unless explicitly authorized by Congress. The House passed the legislation with a vote of 215-208, following a similar measure that had been approved by the Senate weeks earlier.
The resolution was supported by Representatives Thomas Massie (R-KY), Brian Fitzpatrick (R-PA), Tom Barrett (R-MI), and Warren Davidson (R-OH), while Representative Kevin Kiley (I-CA), who aligns with Republicans, voted against it. Fitzpatrick noted that the White House did not lobby him to change his vote, indicating that his stance was well known.
This vote follows a previous attempt by House GOP leadership to delay the resolution, which was pulled before the Memorial Day recess. Earlier this year, only Massie had broken with the White House on a similar vote, but this recent vote saw an increase in Republican defections.
The resolution will now move to the Senate, where its future remains uncertain. Even if it passes, President Trump is expected to veto it. The Senate had previously advanced a version of the bill with a vote of 50-47, with three Republican senators absent. Senators Lisa Murkowski (R-AK), Rand Paul (R-KY), and Susan Collins (R-ME) voted in favor of the measure.
The vote is significant as it tests Trump’s war powers, particularly since the conflict with Iran has exceeded the 90-day limit set by the 1973 War Powers Resolution, which requires presidential military action to be authorized by Congress after that period. The White House contends that the conflict has not yet reached this threshold due to a ceasefire with Iran.
