The Senate voted against a war powers resolution that would prohibit President Trump from taking further military action against Iran. The resolution failed on a mostly party-line vote of 47-52. Only Sens. Rand Paul (R-KY) and John Fetterman (D-PA) voted opposite their parties. The measure failed 47-52, with Sen. Rand Paul, Republican of Kentucky, joining Democrats in voting for the resolution and Sen. John Fetterman, Democrat of Pennsylvania, opposing it. https://t.co/l4tHNtPhL3 — TIME (@TIME) April 15, 2026 CBS News shared further: It was the fourth time Democrats in the Senate had forced a vote on the issue since the war began on Feb. 28. The resolution, led by Democratic Sen. Tammy Duckworth of Illinois, would have directed President Trump “to remove the United States Armed Forces from hostilities within or against Iran, unless explicitly authorized by a declaration of war or a specific authorization for use of military force.” Speaking at a news conference Tuesday, Duckworth said “we cannot let this chaos continue unchecked.” “As our troops continue to sacrifice whatever is asked of them, we senators need to do the absolute minimum required of us,” Duckworth, a former Blackhawk helicopter pilot, said. The Illinois Democrat said the Senate must vote to “end Trump’s illegal war of choice.” Sen. Jim Justice (R-WV) was the only senator not to vote. Although nearly every Republican voted against the resolution, some of them may be likely to switch their votes the longer the Iran war continues. “I will not support ongoing military action beyond a 60-day window without congressional approval,” Sen. John Curtis (R-UT) wrote in an op-ed earlier this month. “I take this position for two reasons – one is historical, and one is constitutional,” he added. Senator John Curtis (R-UT) writes in op-ed that he cannot support funding further military operations in Iran without a formal declaration of war from Congress. https://t.co/kaTjyORQa1 — Politics & Poll Tracker (@PollTracker2024) April 3, 2026 USA TODAY noted: Though the war powers resolution was widely expected to fail, it marked the beginning of a new phase in Democrats’ pressure campaign in Congress to pull U.S. forces from the Middle East war. They vowed to continue calling up similar resolutions in the coming weeks. Those votes will likely become more difficult for Senate Republicans, some of whom have signaled they wouldn’t support continued military operations in the region past a certain date without an official declaration of war or authorization for use of military force from Congress. The War Powers Act requires the president to get a greenlight from Congress after 60 days of war, with an added 30-day grace period.
