Four Republicans voted with nearly every Democrat to discharge the war powers resolution calling for U.S. President Donald Trump to withdraw American forces from hostilities with Iran.
( May 20, 2026 / JNS ) The Senate voted to advance a war powers resolution on Tuesday aimed at halting U.S. hostilities against Iran.
Sens. Bill Cassidy (R-La.), Susan Collins (R-Maine), Lisa Murkowski (R-Alaska) and Rand Paul (R-Ky.) voted with nearly every Democrat to withdraw U.S. forces from the conflict with Iran and confirm that military action against the Islamic Republic has not been authorized by Congress.
Seven similar resolutions have failed to advance in the Senate in previous months. Cassidy switched sides for the first time on Tuesday, and the measure passed 50-47.
