Q: How are IGs appointed and can they be removed?
A: IGs are appointed without regard to their political affiliation. Their appointments are based on their personal integrity and expertise in accounting, auditing, financial analysis, law, management analysis, public administration, and/or investigations. IGs serving at the Cabinet-level departments and major sub-Cabinet agencies are nominated by the President and confirmed by the Senate. These IGs can only be removed by the President.
IGs at independent agencies and corporations are appointed by the agency head. The agency head can also remove them from office.
Whether appointed by the President or the agency head, both Houses of Congress must be notified if an IG is removed from office.
