Specifically, the War Powers Resolution requires the president to provide written notification to Congress of the introduction of U.S. armed forces into hostilities within forty-eight hours of such action. The president must explain the reasons forces were inserted in a hostile situation, the executive’s authority for doing so, and the scope and duration of the military action. In addition, the president is required to terminate the use of military forces after sixty days unless Congress has declared war, extended the period by law, or cannot meet the sixty-day deadline as a result of an armed attack on the United States. The sixty days can be extended for thirty days by the president if the safety of armed forces would be jeopardized by immediate removal. The president is also required to remove forces at any time if Congress so demands by concurrent resolutions (known as a legislative veto). In essence, most members of Congress supported the notion that the president, as commander in chief, is empowered by the Constitution to lead U.S. forces once the decision to wage war is made or an attack on the United States has commenced.
