Senate advances measure to end military action in Iran in rebuke to Trump

Key points

• The Senate on Tuesday advanced a resolution to halt military action in Iran after a surprise defection from Republican Sen.
• Bill Cassidy of Louisiana, dealing a blow to President Donald Trump's war effort.
• The vote, though preliminary, shows that the Senate now could have the votes to force Trump to pull back the military from Iran or seek congressional approval for additional action.
• Despite the War Powers Resolution advancing 50-47, it still has little chance of becoming law.
• It would need to pass a final vote in the Senate, clear the House and Trump would be almost certain to veto it.
