The Department of Justice is the nation's litigator, serving but one client, the United States. The United States Attorneys serve as the Department's principal litigators under the direction of the Attorney General. There are 93 United States Attorneys stationed in judicial districts throughout the United States and its territories. United States Attorneys are appointed by, and serve at the discretion of the President of the United States, with advice and consent of the United States Senate. Each United States Attorney is the Chief Federal Law Enforcement Officer of the United States within his or her particular jurisdiction.
United States Attorneys conduct most of the trial work in which the United States is a party. The United States Attorneys have three statutory responsibilities under Title 28, Section 507 of the United States Code:
- the prosecution of criminal cases brought by the Federal Government;
- the prosecution and defense of civil cases in which the United States is a party; and
- the collection of debt owed to the Federal Government.
Although the caseload varies among districts, each has every category of cases and handles a mixture of simple and complex litigation. Each United States Attorney exercises wide discretion in the use of his or her resources to further the priorities of the local jurisdictions and needs of their communities.
