The President's Cabinet is an institution whose existence rests upon custom rather than law. President George Washington found the Cabinet concept, a meeting of departmental secretaries, to be useful, and all subsequent presidents have followed this precedent. Presidents have differed in their opinions as to the utility of the Cabinet, but all have found some political and administrative strength in its continuance. This report discusses how membership in the Cabinet has changed over the decades. The selection and removal processes are examined as well as commentary on the Cabinet by persons who have been participants.
