Massie files War Powers resolution as GOP libertarians break with leadership

Representative Thomas Massie introduced a War Powers Resolution on March 1, 2026 requiring President Trump to terminate U.S. military operations against Iran within 30 days absent a congressional declaration of war or explicit AUMF. Representatives Rand Paul and Warren Davidson co-sponsored the measure, breaking with House Republican leadership. The resolution was the first formal legislative challenge to Operation Epic Fury and set up a House floor vote that ultimately failed 212-219 on March 5.
