United States Attorneys conduct most of the trial work in cases in which the United States is a party. By law, United States Attorneys have three primary responsibilities under Title 28, Section 547 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 certain debts owed to the Federal Government which are administratively uncollectible.
