Thursday’s House vote would force a fresh test of whether Republicans will require congressional approval for military action against Iran after largely backing Trump through earlier war powers fights.
Democrats pushed the measure as U.S. airstrikes continue, four American service members’ remains returned to Dover, and Defense Secretary Pete Hegseth told senators the war has cost $37.5 billion so far.
Republicans have begun pressing for more clarity on the endgame and Hormuz disruptions, but party leaders still defend the war and Speaker Mike Johnson has lobbied members against the resolution.
Polling has sharpened the political risk: most Americans say the war is not worth fighting, and even within the GOP only about two-thirds approve of Trump’s handling of Iran.
