Congress passes war powers resolution directing Trump to end Iran hostilities.

The U.S. Senate voted 50-48 on June 23, 2026, to approve a House-passed war powers resolution directing President Trump to remove U.S. armed forces from hostilities against Iran. Four Republican senators joined all Democrats except John Fetterman in supporting the measure, which is a concurrent resolution that does not require the president's signature. The vote marked the first time both chambers of Congress passed such a measure since the war began on February 28, 2026.
