Defense Secretary Pete Hegseth said the U.S. war against Iran has cost $37.5 billion so far. Hegseth is facing questions and protests at a Senate hearing ahead over the U.S. war against Iran. Hegseth and other officials are appearing as Republicans push a $95 billion budget package to fund the military, along with aid to farmers and voting law changes that are top White House priorities. Their appearance comes after it was announced that three more American service members have died in the conflict, bringing the death toll to 17. The Pentagon also disclosed that more than 100 have been injured. Hegseth said the funds are “urgent, necessary.” But Sen. Patty Murray, the top Democrat on the panel, said the war is “spiraling out of control.”
