To trigger an audit or investigation by the 
Department of Defense (DoD), file a complaint 
regarding fraud, waste, abuse, or mismanagement 
through the DoD Hotline at 800-424-9098 or 
their website. Complaints can be submitted 
anonymously, though providing contact 
information helps investigators, and the 
process is confidential.
