Senate Republicans block war powers resolution on Iran

In March 2026, Senate Republicans, along with one Democrat, blocked a war powers resolution intended to prevent President Trump from engaging in war with Iran. The vote took place in the U.S. Senate as fighting between the two nations escalated across the Middle East. This marked the first Congressional vote addressing the conflict. The resolution aimed to limit the President's authority to wage war against Iran without Congressional approval. The defeat of the resolution allows the President to continue military actions against Iran without explicit Congressional authorization.
