Some inspectors general, the heads of the offices, are appointed by the president and confirmed by the Senate. For example, both the inspector general of the U.S. Department of Labor and the inspector general of the U.S. Agency for International Development are presidentially appointed. The remaining inspectors general are designated by their respective agency heads, such as the U.S. Postal Service inspector general. Presidentially appointed IGs can only be removed, or terminated, from their positions by the President of the United States, whereas designated inspectors general can be terminated by the agency head. However, in both cases Congress must be notified of the termination, removal, or reassignment.
