Senate Passes Resolution to Limit Presidential War Powers Regarding Iran

On June 23, 2026, the Senate passed a resolution directing President Donald Trump to withdraw military forces from the conflict with Iran, reflecting a lack of congressional support for the war. The vote was 50-48, with bipartisan support from some Republican senators including Rand Paul, Susan Collins, Lisa Murkowski, and Bill Cassidy. Democratic Senator John Fetterman voted against the resolution. The measure had previously passed the House with a vote of 215-208. As a concurrent resolution, it does not require the president's signature and does not have the force of law. A White House official dismissed the resolution as insignificant, citing a lack of hostilities from which to withdraw U.S. forces. This marks the tenth Senate vote on Iran war powers measures this year. Some Democratic senators, like Tim Kaine, argue that congressional involvement is necessary to prevent future escalations.
