The U.S. Senate on Wednesday voted down a War Powers Resolution intended to restrict President Donald Trump’s military actions against Iran.
The resolution also failed to advance out of committee.
Background and legal basis
The measure invoked the 1973 War Powers Act, which requires presidents to consult Congress before introducing U.S. forces into hostilities and limits such engagements to 60 days without authorization.
Senators Tim Kaine (D-VA) and Rand Paul (R-KY) sponsored the Senate version of the proposal.
Supporters’ arguments
Backers said the resolution would prevent open-ended conflict and restore congressional oversight over prolonged military engagements.
A similar measure introduced by Reps. Thomas Massie (R-KY) and Ro Khanna (D-CA) was scheduled for House consideration on Thursday.
Vote details and dissenters
The motion to discharge the resolution from the Foreign Relations Committee failed by a 47-53 vote.
The tally largely followed party lines, with 46 Democrats and one Republican supporting advancement while 52 Republicans and one Democrat opposed it.
Senator Paul was the lone Republican to vote for the resolution and Senator John Fetterman (D-PA) was the lone Democrat to vote against it.

Senators’ remarks
Senator Paul invoked the wars in Iraq and Afghanistan when explaining his reasoning for introducing the measure.
“Sometimes it turns out worse to be anticipated. Nobody thought when they voted for the war in Afghanistan that we’d be there 20 years and spend $2 trillion,” he said.
Senator Lindsey Graham (R-SC) told reporters the resolution “sucks” and said it would create “an unconstitutional shift of power from the commander in chief to the Congress.”
Consequences and next steps
The rejection leaves President Trump with broad latitude to conduct military operations against Iran without needing immediate congressional approval.
The outcome affirms the executive branch’s interpretation of its authority under the War Powers Act and prior authorizations, allowing continued strikes and support for allies like Israel amid the conflict, which began five days prior.
If the House adopts a similar measure on Thursday, the Senate could face another attempt soon.
War Powers measures benefit from procedural privileges that enable the minority party to compel votes and bypass typical committee hurdles, as noted in coverage that benefit from those rules.
