On June 13, 2026, a bipartisan majority in Congress voted in favor of a war powers resolution to remove U.S. armed forces from hostilities with Iran. The Senate vote tally was 50 to 48, with notable support from four Republicans: Bill Cassidy of Louisiana, Susan Collins of Maine, Rand Paul of Kentucky, and Lisa Murkowski of Alaska.

The resolution is non-binding and will not be presented to the White House for presidential approval; however, it had already been approved by the House earlier in the month. Senate Minority Leader Chuck Schumer, a Democrat from New York, stated, “Today, Congress stood up to Donald Trump and voted to end his costly, unnecessary, and devastating war with Iran.” He emphasized the clarity of Congress’s message, given its authority to declare war, for the Trump administration to cease U.S. military involvements in Iran.

President Trump expressed his disapproval of the resolution following its passage in the House. He commented on Truth Social, criticizing lawmakers for their timing. He described the action as “unpatriotic” and accused Democrats of being motivated by “Trump Derangement Syndrome,” prioritizing personal success over national interests.

The timing of Tuesday’s vote aligns with ongoing delicate negotiations between the U.S. and Iran aimed at conclusively ending the conflict. The preliminary terms of these negotiations have been widely contested by representatives from both major political parties.
