United States Department of Justice Criminal Division

The U.S. Department of Justice Criminal Division develops, enforces, and supervises the application of all federal criminal laws in the United States, except those specifically assigned to other divisions. Criminal Division attorneys prosecute many nationally significant cases and formulate and implement criminal enforcement policy. Division attorneys also provide advice and guidance to the Attorney General of the United States, the United States Congress, and the White House on matters of criminal law.

The Criminal Division is headed by an Assistant Attorney General, appointed by the President of the United States. On April 20, 2009, President Barack Obama appointed Lanny A. Breuer as the Assistant Attorney General for the Criminal Division. After Breuer's resignation, he was replaced by Mythili Raman as of March 1, 2013. Mythili Raman was replaced by Leslie R. Caldwell via presidential appointment.

The Criminal Division is headed by an Assistant Attorney General, who is a political appointee. The Assistant Attorney General is assisted by five Deputy Assistant Attorneys General, who are career attorneys, who each oversee a Branch of the Division. Each of the Branches consist of various sections, offices and units.

The Criminal Division's Counterterrorism and Counterespionage Sections were transferred to the National Security Division in 2005 with the reauthorization of the USA PATRIOT Act.
