Department of Justice

The U.S. Department of Justice (DOJ) enforces federal law, represents the United States in court, manages federal corrections, and works to protect public safety and civil rights across the country.

Investigations & law enforcement

DOJ investigative agencies pursue criminals and emerging threats, including the rise of powerful synthetic drug mixtures like xylazine (”tranq”) with fentanyl, and run public-safety programs such as DEA prescription Take Back efforts to safely dispose of prescription drugs.

Litigation & enforcement

DOJ attorneys handle criminal prosecutions, antitrust suits, tax enforcement, and civil rights cases — for example, the department’s recent settlement with RealPage and ongoing work in criminal tax enforcement.

Corrections, alternatives, and public access

The Bureau of Prisons manages federal inmates and the DOJ provides tools to find a federal inmate. The department also supports alternatives to incarceration, such as drug courts that emphasize treatment over punishment.

The department’s leadership and independence are often subjects of national debate, including discussions about how attorneys general balance politics and independence and recent controversies such as claims about administrative control of DOJ and high-profile funding disputes.

Practical rules & services

For regulated individuals, the DOJ and its agencies publish practical guidance — for example, how to update your firearms license when moving.
