Administrative Investigations

Marguerite C. Garrison, Deputy Inspector General for Administrative Investigations


Administrative Investigations (AI) helps ensure ethical conduct throughout the DoD by conducting investigations and overseeing DoD Component investigations of allegations of misconduct by senior DoD officials, whistleblower reprisal, and Service member restriction from communication with an IG or Member of Congress.  AI also manages the DoD Hotline and the Contractor Disclosure Program, provides education and training on whistleblower protections through its Whistleblower Protection Coordinator, and facilitates voluntary resolution of whistleblower reprisal allegations through its Alternative Dispute Resolution program.
