For the First Time in History, Both Chambers of Congress Passed a War Powers Resolution to Stop a President's War — Trump's Own Party Helped Do It
On June 23, 2026, the Senate voted 50-48 to direct President Trump to remove U.S. forces from hostilities against Iran — the first time in the 53-year history of the War Powers Act that a resolution to halt a president's war has passed both chambers of Congress. The House had passed the same concurrent resolution on June 3 by 215-208. Because it is a concurrent resolution, it does not require Trump's signature. Four Republican senators — Susan Collins, Lisa Murkowski, Bill Cassidy, and Rand Paul — broke ranks to join the Democrats; the measure cleared the chamber partly because Mitch McConnell and Dave McCormick, who had blocked earlier attempts, did not vote. It was the tenth time the Senate had tried to stop the war. Sen. Tim Kaine, who led the effort, said: "The most solemn power for Congress is Congress has the power to declare war, not the president." Kaine pressed the vote even with talks underway in Switzerland and pointed to the administration's request for $80 billion in emergency spending to rebuild munitions depleted since the war began on Feb. 28. Trump called the House version "a meaningless vote" and branded the Republicans who crossed him "GRANDSTANDERS." The rebuke is historic precisely because it required Congress to formally tell a president to stop a war that his own intelligence community said was never necessary.
