U.S. Department of Justice (DOJ)
The mission of the Department of Justice is to enforce the law and defend the interests of the United States according to the law; to ensure public safety against threats foreign and domestic; to provide federal leadership in preventing and controlling crime; to seek just punishment for those guilty of unlawful behavior; and to ensure fair and impartial administration of justice for all Americans. In 1870, Congress passed the Act to Establish the Department of Justice, setting it up as "an executive department of the government of the United States" with the Attorney General as its head. Officially coming into existence on July 1, 1870, the Department of Justice was to handle the legal business of the United States. The Act gave the Department control over all criminal prosecutions and civil suits in which the United States had an interest. In addition, the Act gave the Attorney General and the Department control over federal law enforcement. The structure of the Department of Justice has changed over the years, with the addition of the Deputy Attorneys General and the formation of the Divisions. Unchanged is the steadily increasing workload of the Department. It has become the world's largest law office and the central agency for enforcement of federal laws.
