The Republican-led U.S. Senate on Tuesday [passed a War Powers Resolution to end hostilities in Iran](https://nebraskaexaminer.com/2026/06/23/repub/us-senate-joins-house-in-rebuke-of-trump-over-his-war-in-iran/), marking the first time both chambers of Congress have agreed to challenge President Donald Trump's military campaign against the Islamic Republic. The concurrent resolution passed 50-48, with four Republicans breaking ranks to join nearly all Democrats in the vote.

The measure [directs the president to remove U.S. armed forces from hostilities against Iran](https://www.senate.gov/legislative/LIS/roll_call_votes/vote1192/vote_119_2_00184.htm) and does not require Trump's signature. The Senate's approval came after the House passed the same resolution earlier this month with four Republicans also voting in favor.

Republicans who voted for the measure were Sens. Lisa Murkowski of Alaska, Rand Paul of Kentucky, Bill Cassidy of Louisiana and Susan Collins of Maine. Cassidy recently lost his primary race following Trump's endorsement of an opponent, while Collins faces a tough reelection campaign. Democrat John Fetterman of Pennsylvania broke with his party to vote against the measure. Sens. Mitch McConnell of Kentucky and Dave McCormick of Pennsylvania did not vote.

Senate Minority Leader Chuck Schumer characterized the vote as a powerful rebuke of Trump's foreign policy. "Congress never authorized this war, and the president certainly has no authority to continue it indefinitely without our consent," said Rep. Gregory Meeks, D-N.Y., the sponsor of the original House resolution and top Democrat on the House Foreign Affairs Committee.

The Trump administration and Secretary of State Marco Rubio have argued that War Powers Resolutions lack constitutional authority, citing a 1983 Supreme Court ruling against congressional measures not requiring presidential signature. The White House declined to comment on Tuesday's vote. The resolution faces an uncertain future, as [Trump is expected to veto the measure](https://www.aljazeera.com/news/2026/6/23/us-senate-votes-to-halt-iran-war-bucking-trump) if it reaches his desk.

The Senate vote occurred as [the Trump administration and Iran continue negotiations](https://www.newsfromthestates.com/article/60-day-clock-starts-negotiations-iran-over-strait-nuclear-future) on a comprehensive deal. The 60-day negotiation window began under a June 17 memorandum of understanding that lifted the U.S. naval blockade of Iranian ports and sanctions on Iranian oil exports. The interim deal requires Iran to clear mines from the Strait of Hormuz and allow commercial shipping to pass unimpeded. The Pentagon has reported 13 American service members killed and over 400 injured in the conflict that began Feb. 28, with thousands of civilians killed across Iran and the Persian Gulf region.
