US Senate fails to advance war powers measure to rein Trump’s war with Iran

The US Senate failed to pass a resolution on March 4, 2026, that aimed to limit President Trump's military actions in the ongoing war with Iran. The resolution, which sought to reassert Congress's authority to authorize or end military actions, was defeated in a 47-52 procedural vote. Supporters of the resolution argued that Trump exceeded his constitutional authority by launching a war alongside Israel without congressional approval, citing the lack of imminent threat to the US. Republicans largely supported Trump, while the administration offered various justifications for the war, including Iran's alleged pursuit of nuclear weapons and long-range missiles. A similar resolution is scheduled for a vote in the House of Representatives, but its prospects are uncertain.
