What are the provisions of the war powers act?

The War Powers Resolution requires the president to notify Congress within 48 hours of committing armed forces to military action and forbids armed forces from remaining for more than 60 days, with a further 30-day withdrawal period, without congressional authorization for use of military force (AUMF) or a declaration.

Explanation:

Congress passed the War Powers Resolution in the aftermath of the Vietnam War to address these concerns and provide a set of procedures for both the President and Congress to follow in situations where the introduction of U.S. forces abroad could lead to their involvement in armed conflict

Nixon vetoed the War Powers Resolution on this date. The legislation highlighted a significant constitutional issue: the President is the commander and chief of American armed forces, but Congress has the sole power to declare war. The legislature overrode Nixon's veto in November 1973.
