The US Senate has voted to end unauthorized military action against Iran, delivering a rare bipartisan rebuke to former President Donald Trump’s foreign policy. The measure passed with support from both Democrats and a handful of Republican senators, signaling growing congressional concern over potential escalation with Iran. Senators Lisa Murkowski (Alaska), Bill Cassidy (Louisiana), Susan Collins (Maine), and Rand Paul (Kentucky) joined Democrats in approving the resolution. The vote aims to reassert Congress’s constitutional authority over war powers, challenging the executive branch’s ability to initiate military conflict without explicit congressional approval. Supporters argue the resolution clarifies that Congress, not the President, holds the power to declare war. While the resolution is largely symbolic given Trump is no longer in office, it establishes a formal Senate record opposing further military engagement with Iran. The Biden administration has not stated its position on the measure.
