WASHINGTON, DC - APRIL 22: U.S. Senate Majority Leader John Thune (R-SD) leaves a luncheon with Senate Republicans in the U.S. Capitol Building on April 22, 2026 in Washington, DC. The Senate is expected to vote again on a procedural measure tied to a Senate Democrat-backed Iran War Powers Resolution, following the fourth rejection of the proposal. If passed, it would limit U.S. President Donald Trump’s ability to use military force against Iran. (Photo by Anna Moneymaker/Getty Images)
