ATLANTA (AP) — Potential grand jurors are scheduled to arrive at the Fulton County courthouse in Atlanta on Monday for the seating of a special grand jury in the investigation into whether former President Donald Trump and others illegally tried to influence the 2020 election in Georgia.

The investigation has been underway since early last year, and Fulton County District Attorney Fani Willis earlier this year requested a special grand jury to help it along.

In a letter to the chief judge of the county Superior Court, she noted that the special grand jury would be able to issue subpoenas to people who have refused to cooperate otherwise.

The chief judge ordered the special grand jury to be seated for a period of up to a year, beginning Monday
