U.S. Senate passes resolution to halt military action against Iran

On June 25, the U.S. Senate voted 50‑48 to adopt a war‑powers resolution that directs President Donald Trump to withdraw American armed forces from hostilities with Iran unless Congress explicitly authorises further action. Four Republican senators—Bill Cassidy, Lisa Murkowski, Susan Collins and Rand Paul—joined Democrats in supporting the measure; Republican John Fetterman was the sole Democratic opponent.

The resolution mirrors an earlier House vote of 215‑208 and marks the first time both chambers have passed a binding joint resolution under the War Powers Act directing a president to pull troops from a warzone. Senate Majority Leader Chuck Schumer praised the vote, saying the war has "cost the American people" and that the resolution “puts Iran on notice.” President Trump denounced the Senate action as “meaningless” and “badly timed,” accusing lawmakers of undermining U.S. leverage.

While the Senate view the measure as a check on executive authority, the White House contends that concurrent resolutions have no legal force and that active hostilities have already ended. The debate highlights growing congressional scrutiny of presidential war powers amid ongoing tensions with Tehran.
