Frequently Asked Questions

What is a federal grand jury?

Federal prosecutors charge most cases by presenting evidence to a federal grand jury which is made up of jurors. The grand juries serve two functions: they investigate cases through reviewing documents and hearing witness testimony, and they return indictments when they find probable cause to believe that a defendant has committed the crime charged. By law, grand juries operate in secret.
