History of the U.S. Attorneys
Established by the Judiciary Act or 1789, the United States Attorneys serve as the chief federal law enforcement officers in their districts and are responsible for coordinating multi-agency investigations. U. S. Attorneys are appointed by the President of the United States, with the advice and consent of the United States Senate, and serve at the direction of the Attorney General. There are a total of 93 U.S. Attorneys appointed throughout the United States and its territories, each responsible for a specific judicial district.
