Assistant district attorney

A district attorney (D.A.) is, in some U.S. jurisdictions, the title of the local public official who represents the government in the prosecution of criminals. The district attorney is the highest officeholder in the jurisdiction's legal department and supervises a staff of assistant district attorneys. Similar functions are carried out at the local level in other jurisdictions by officers named the Commonwealth's Attorney, State's Attorney, County Attorney, or County Prosecutor. Depending on the system in place in the particular state or county, district attorneys may be appointed by the chief executive of the region or elected by the people.
