Senate Republicans have blocked a war powers resolution related to Iran for the sixth time, delaying congressional action on potential military authorization. The resolution would have established procedures for congressional approval of military action against Iran.
The blocking maneuver comes as a 60-day deadline approaches under the War Powers Resolution of 1973, which requires congressional authorization for sustained military operations.
Supporters of the resolution argue it would maintain congressional oversight of military decisions, while opponents say it could tie the president's hands in responding to threats.
The ongoing tension with Iran centers on its nuclear program and regional activities. Diplomats from both countries continue talks despite the congressional deadlock.
