Attorneys in the Criminal Division handle the investigation and prosecution of all types of federal crimes, ranging from petty offenses (including traffic and wildlife offenses) to complex white collar crime, federal homicides, drug trafficking, offenses impacting national security and civil rights, and public corruption cases.

Additionally, the Unit, in consultation with the Department of Justice, decides when to seek appellate review of trial level rulings adverse to the United States.
The Executive Unit is comprised of senior attorneys who investigate and prosecute a wide variety of offenses. Prosecutors assigned to the Unit prosecute violent crime and drug trafficking offenses, white-collar financial crimes, public corruption cases, complex health-care fraud schemes, and capital crimes.
