The Office of the Inspector General (OIG) in the U.S. Department of Justice (DOJ) is a statutorily created independent entity whose mission is to promote integrity, efficiency, and accountability within the Department of Justice. The OIG investigates alleged violations of criminal and civil laws by DOJ employees and also audits and inspects DOJ programs. The Inspector General, who is appointed by the President subject to Senate confirmation, reports to the Attorney General and Congress.
The Office of the Inspector General (OIG) consists of a front office, which is comprised of the Inspector General, the Deputy Inspector General, the Office of the General Counsel, and six major components. Each division is headed by an Assistant Inspector General.
Michael E. Horowitz was confirmed as Inspector General for the Department of Justice (DOJ) by the U.S. Senate on March 29, 2012. He was sworn in as the fourth confirmed Inspector General on April 16, 2012. See More

The Audit Division is the OIG’s largest division and is made up of 200 skilled auditors, program analysts, statisticians and other operational staff. Through its multi-disciplined staff, the Audit Division conducts performance audits of Department programs and operations and oversees annual audits of over $35 billion in Department expenditures. The Division also conducts audits of external entities that receive Department funding through its various contracts and grant programs. These audits significantly assist the Department in its efforts to prevent waste, fraud and abuse, and to promote economy and efficiency in its operations. The Division’s robust oversight program is primarily driven by risk-based assessments of Department operations, as well as legal mandates, congressional requests, current events, and the Department’s Top Management and Performance Challenges as identified by the OIG each year.

The Evaluation and Inspections Division provides the Inspector General with an alternative mechanism to traditional audit and investigative disciplines to assess Department of Justice (Department) programs and activities. Much of the work results in recommendations to decisionmakers to streamline operations, reduce unnecessary regulations, improve customer service, and minimize inefficient and ineffective procedures. In addition to assessing Department programs through on-site inspections and program evaluations, the Division conducts special reviews requested by the Inspector General or senior Department management that arise suddenly and need immediate attention.
Assistant Inspector General (Acting) – René Rocque Lee
