Senate Rejects War Powers Resolution Limiting Trump's Iran Conflict

The U.S. Senate narrowly rejected a Democratic-led war powers resolution on Tuesday in a 48-47 vote, marking the ninth failed attempt by lawmakers to curb military action against Iran. The measure, sponsored by Senator Raphael Warnock, would have required Donald Trump to remove U.S. forces from hostilities and seek congressional approval for continued involvement. Four Republicans—Bill Cassidy, Susan Collins, Lisa Murkowski, and Rand Paul—joined nearly all Democrats in support, while Democrat John Fetterman was the sole opponent.

The vote occurred as the administration prepared to sign a preliminary agreement in Switzerland on Friday to establish a 60-day ceasefire and negotiation period. While the U.S. House of Representatives previously passed a similar measure to limit war powers, Senate Republicans argued that legislative interference could cause Iran to abandon the pending peace deal.

Lawmakers expressed frustration over a lack of detailed briefings regarding the secret framework agreement. Senate Majority Leader John Thune and other members requested the text of the memorandum of understanding to review its terms. Senator Tim Kaine vowed to continue proposing similar measures weekly to ensure constitutional consultation with Congress and prevent the resumption of strikes during the current fragile ceasefire.
