U.S. Attorneys are federal prosecutors who represent the United States in legal matters. They work in each of the 94 federal judicial districts and are responsible for prosecuting criminal cases brought by the federal government, as well as handling civil litigation involving the U.S. They are appointed by the President and confirmed by the Senate. In addition to prosecuting cases, U.S. Attorneys also provide legal advice to federal agencies and may oversee investigations. They play a crucial role in enforcing federal laws, including those related to drug trafficking, immigration, and white-collar crime. Their work helps ensure justice and uphold the rule of law in the country.
