The US Senate voted 50-48 on June 23 to approve a war powers resolution aimed at halting military operations against Iran, marking the first time such a measure has cleared both chambers of Congress since hostilities began in late February.
Four Republican senators crossed party lines to join Democrats in backing the resolution. The House had already passed its own version earlier in June by a similarly razor-thin margin of 215-208.
A rare congressional rebuke
US and Israeli military strikes commenced on February 28, 2026. In the roughly four months since, the conflict has generated increasing unease on Capitol Hill, particularly among members of the president’s own party.
The Trump administration has dismissed these congressional efforts as unconstitutional, a position that sets up a constitutional standoff even if the resolution itself carries no binding legal force. It doesn’t require Trump’s signature, which means it functions more as a political statement than an enforceable directive.
