The U.S. Marshals Service is a federal law enforcement agency under the Department of Justice. Established in 1789, it is responsible for apprehending fugitives, managing and transporting prisoners, and executing federal court orders. The agency plays a crucial role in maintaining the integrity of the judicial system. In addition to its primary duties, the U.S. Marshals also provide protection for witnesses and manage seized assets. They work closely with other law enforcement agencies, including the FBI and DEA, to ensure public safety and enforce federal laws across the United States.
