The US Senate has rejected a war powers resolution that would have directed President Donald Trump to end military hostilities against Iran, with the measure falling short in a 49-50 vote. The vote divided largely along party lines, though Republican senators Susan Collins, Lisa Murkowski, and Rand Paul broke with their party to support the resolution, while Democrat John Fetterman crossed the aisle to oppose it. The defeat means Congress has again failed to exercise its constitutional authority to check the president's use of military force in the Middle East, leaving Trump free to continue operations against Iran.
