The United States Department of Justice (DOJ), also known as the Justice Department, is a federal executive department of the U.S. government, responsible for the enforcement of the law and administration of justice in the United States, equivalent to the justice or interior ministries of other countries. The department was formed in 1870 during the Ulysses S. Grant administration.
The department is headed by the United States Attorney General, who is nominated by the President and confirmed by the Senate and is a member of the Cabinet. The current Attorney General is Jeff Sessions.
The Department of Justice officially began operations on July 1, 1870. Just prior to the American Civil War, in February 1861, the Confederate States of America established a Department of Justice. Though “[t]he second American department of justice was brought into being on July 1, 1870, fifty years of amendments were required before it reached a status comparable to that of its Confederate predecessor.”
