Inspector General
An inspector general (IG) is an independent watchdog office inside a federal department or agency, charged with auditing its programs and investigating waste, fraud, and abuse. Inspectors general are established by statute (the Inspector General Act of 1978 and later expansions); they are appointed without regard to political affiliation, can only be removed by the President communicating reasons to Congress, and report both to the agency head and, importantly, directly to Congress.

Example: The Inspector General Act of 1978 (P.L. 95-452) created the first statutory IG offices in the largest departments and agencies, and Congress later extended IGs across most of the executive branch — a 2022 codification moved the Act provisions into Title 5 of the U.S. Code.
Common misconception: An inspector general is not part of the agency management chain and does not work for the officials it oversees. Independence is the design: IGs issue their own reports, refer findings to prosecutors when warranted, and their value depends on being able to criticize the very department that houses them.
