The US Senate passes a war powers resolution that rebukes President Donald Trump’s military actions against Iran, joining the House earlier this month. The measure is approved by a 50–48 vote, with four Republicans joining most Democrats. It instructs the president to withdraw US forces from hostilities with Iran unless Congress explicitly authorises further military action. Multiple outlets describe the action as largely symbolic because it is a “concurrent resolution” and therefore does not go to the president for signature; its legal force is disputed. Still, the passage marks the first time a House-passed war powers measure reaches both chambers since the Iran conflict began in late February.

The resolution comes as the Trump administration pursues a 60-day diplomatic effort to turn an initial memorandum of understanding with Iran into a broader settlement covering Tehran’s nuclear programme, sanctions relief and the Strait of Hormuz. Democrats argue Trump violated the Constitution by initiating or continuing military operations without congressional approval. Trump and allied Republicans argue that congressional limits during negotiations are dangerous, while Democratic leaders say the vote is intended to ensure the conflict ends and to place Congress on record against further hostilities.
