Under the War Powers Resolution, a president is required to notify Congress of any impending military action within 48 hours of deployment and must remove troops after a 60 day period unless Congress itself authorizes further action. The White House could also seek a 30-day extension from Congress.

The War Powers Resolution sets deadlines for the president to end hostilities without congressional approval.

This case of executive overreach by Nixon in Cambodia during the Vietnam War led to the passage of the War Powers Act on Nov. 7, 1973.

U.S. officials say the Iran ceasefire ended hostilities and reset the War Powers clock, but legal experts say military operations complicate that.

It was an attempt to move forward a resolution that would have opened debate about ending U.S. military operations against Iran.

Rep. Jared Golden (D-Maine) was the sole Democrat to vote against the resolution.
