House Republican leadership pulls Iran war powers floor vote after Senate advances resolution 50-47

House Republican leadership canceled a scheduled floor vote on the Iran War Powers Resolution on May 21, 2026, one day after the Senate advanced a companion resolution 50-47. Speaker Mike Johnson's office cited insufficient Republican support for blocking the measure and redirected members to committee deliberations. The cancellation broke the procedural sequence that would have forced a floor vote under the War Powers Resolution, allowing Trump's Iran military operations to continue without a congressional floor vote in either chamber.
