US Senate approves resolution to limit Trump’s authority on Iran military action

WASHINGTON, United States — WASHINGTON — The U.S. Senate on Tuesday approved a resolution calling on President Donald Trump to end military operations against Iran without explicit authorization from Congress, a measure designed to halt ongoing strikes under a clearer legal framework. The resolution, passed this evening, urged the president to cease U.S. military activity directed at Iran in the absence of formal congressional approval, according to the Senate record. Lawmakers had previously rejected a similar Democratic-led effort on May 15, 2026, by a narrow margin, but the latest vote marked the third time in the past year that Congress has weighed in on war powers related to Iran. The development comes as debate continues in Washington over subjecting military policy toward Iran to congressional oversight.
