United States Senate advances War Powers Resolution regarding military force against Iran on 20 May 2026

Exam-focused facts from the 21 May 2026 current affairs briefing.

Key facts

The United States Senate passed a procedural measure to advance a War Powers Resolution to prevent President Donald Trump from using military force against Iran without congressional authorisation.
The procedural vote to advance the resolution was passed by a margin of 50 to 47.
The war on Iran was launched by the United States and Israel in late February.
Under a 1973 US war powers law, a president can wage military action for only 60 days before requiring congressional authorisation or a 30-day extension.
To survive a presidential veto, the resolution must pass the Republican-led House of Representatives and secure two-thirds majorities in both the House and Senate.
