The Cabinet of the United States is the principal official advisory body to the president of the United States. The Cabinet generally meets with the president in a room adjacent to the Oval Office in the West Wing of the White House. The president chairs the meetings but is not formally a member of the Cabinet. The vice president of the United States serves in the Cabinet by statute. The heads of departments, appointed by the president and confirmed by the Senate, are members of the Cabinet, and acting department heads also participate in Cabinet meetings whether or not they have been officially nominated for Senate confirmation. Members of the Cabinet are political appointees and administratively operate their departments. As appointed officers heading federal agencies, these Cabinet secretaries are executives with full administrative control over their respective departments. The president may designate heads of other agencies and non-Senate-confirmed members of the Executive Office of the President as members of the Cabinet.
