The US Senate voted 49–50 on Thursday to reject a war powers resolution that would have halted President Donald Trump's ongoing military campaign against Iran, now in its seventh month and estimated to have cost $43.5 billion. Four Republican senators — Susan Collins, Lisa Murkowski, Rand Paul, and Thom Tillis — crossed party lines to support the measure, though the effort fell short of the majority needed to pass. The vote comes amid growing public frustration over soaring fuel costs, with diesel prices nearly doubling to over $6 a gallon, turning the conflict into a significant issue ahead of November's midterm elections.
