The War Powers Act is a federal law intended to check the U.S. president's power to commit the United States to an armed conflict without the consent of the U.S. Congress. This act was passed by Congress over President Nixon's veto to increase congressional control over the executive branch in foreign policy matters, specifically in regard to military actions short of formally declared war.
