A body of citizens who listen to evidence of criminal allegations, which are presented by the government, and determines whether there is probable cause to believe the offense was committed. As it is used in federal criminal cases, “the government” refers to the lawyers of the U.S. Attorney’s office who are prosecuting the case. Grand jury proceedings are closed to the public, and the person suspected of having committed the crime is not entitled to be present or have an attorney present. States are not required to use grand juries, but the federal government must do so under the Constitution. (https://www.justice.gov/usao/justice-101/glossary)
