In the United States, a District Attorney represents the state government in the prosecution of criminal offenses, and is the chief law enforcement officer and top prosecutor of that state's jurisdiction.
The United States of America, commonly referred to as the United States or America, is a federal republic composed of 50 states, a federal district, five major self-governing territories, and various possessions.
Jurisdiction is the practical authority granted to a legal body to administer justice within a defined field of responsibility, e.g., Michigan tax law.

The district attorney leads a staff of prosecutors, Assistant District Attorneys, who represent the State and investigate and prosecute criminals on behalf of the District Attorney.
The prosecutor is the chief legal representative of the prosecution in countries with either the common law adversarial system, or the civil law inquisitorial system.
Depending upon the system in place, DAs may be appointed by the chief executive of the jurisdiction or elected by the voters of the jurisdiction.
The prosecution is the legal party responsible for presenting the case against an individual who is suspected of breaking the law, initiating and directing further criminal investigations, guiding and recommending the sentencing of offenders, and are the only attorneys allowed to participate in grand jury proceedings.
