ATLANTA (AP) — The Georgia prosecutor investigating possible attempts to interfere in the 2020 general election by former President Donald Trump and others has asked for a special grand jury to aid the investigation. Fulton County District Attorney Fani Willis on Thursday sent a letter to Fulton County Superior Court Chief Judge Christopher Brasher asking him to impanel a special grand jury. Willis wrote that her office has tried to interview multiple witnesses and gather evidence, and some witnesses and prospective witnesses have refused to cooperate without a subpoena. A special grand jury would have the power to subpoena witnesses.
