The U.S. Senate on Thursday rejected a resolution that would have urged President Donald Trump to end the U.S. war in Iran, voting 49‑50 in favour of keeping the conflict alive. The measure, a symbolic rebuke that would not require the president’s signature, was supported by 50 senators, all but a handful of Republicans, and opposed by 49, including the lone Democrat to vote no, Senator John Fetterman of Pennsylvania.

Only four Republicans crossed party lines to support the resolution: Senators Rand Paul of Kentucky, Susan Collins of Maine, Lisa Murkowski of Alaska and Thom Tillis of North Carolina. The majority of GOP senators, including those in competitive 2026 races such as Jon Husted of Ohio and Dan Sullivan of Alaska, voted against the measure. The resolution had previously passed the House in July with a 214‑208 vote.

The vote comes amid growing public opposition to the war. A recent NBC News poll found that only 33% of registered voters believe the Iran war was worth it, while 62% say it was not. The war, which began in February 2026, has already cost the United States an estimated $38 billion and resulted in 19 U.S. service members’ deaths.

Senator Tim Kaine of Virginia, who has led the Senate push to reassert congressional war‑powers, said the resolution was a message that “Congress has the constitutional power to declare war, not the president.” He added that the measure would pressure Trump to heed the American public’s concerns and the families of fallen soldiers.

Republican candidates in competitive races have begun to distance themselves from Trump’s war stance. Iowa GOP Senate candidate Ashley Hinson, who had previously voted against six House resolutions to end the war, called for an immediate end to the conflict and economic relief for Iowans. The Cook Political Report now rates her race as a toss‑up.
