Senate blocks Iran War Powers resolution for fourth time, 47-52

The Senate voted 47-52 on April 15, 2026 to block a Democratic war powers resolution invoking the War Powers Resolution to end U.S. military involvement in Iran — the fourth such defeat since war began February 28. Republican Sen. Rand Paul joined all voting Democrats in supporting the measure; Democratic Sen. John Fetterman voted with Republicans against it. Democrats argued Trump's airstrikes and naval blockade required a congressional AUMF. Three Republican senators who broke with leadership increased pressure on GOP heading into the May 1 War Powers clock deadline.
