House Republicans joined Democrats in a 214–208 vote to direct President Trump to end unauthorized military action against Iran, while the Senate blocked a similar measure 49–47, reflecting a congressional divide over war powers.
The U.S. Senate voted 50-48 to approve a war powers resolution instructing President Trump to halt military operations against Iran or seek congressional authorization, with four Republicans joining Democrats. This marks the first time both chambers of Congress have passed such a resolution, delivering a bipartisan rebuke to the president's war powers.
The U.S. Senate blocked the latest Democratic-led effort to force President Trump to halt military operations in Iran and seek congressional authorization, with only four Republican senators crossing party lines to support the measure. This marks the ninth such attempt by Democrats since U.S. and Israeli air attacks on Iran began in February 2026.
President Trump engaged in a heated shouting match with Senator Bill Cassidy and other Republicans during a closed-door lunch meeting over his Iran war framework deal, as Congress voted on measures to restrict his war powers. The confrontation came amid growing GOP discontent over a deal that critics say fails to achieve the administration's stated goals.
Republican lawmakers who initially deferred to President Trump on the Iran conflict are now facing constraints in their ability to impose war powers limitations, having missed crucial legislative milestones to establish parameters and exit criteria for the ongoing military engagement.
