It has not charged Mr Trump.

But Mr Trump is believed to be one of the unindicted co-conspirators listed in the sweeping indictment released last month.

Altogether, Arizona has charged 18 Republicans for allegedly claiming Mr Trump won Arizona, when in truth the Democratic nominee, President Joe Biden, carried the state by more than 10,000 votes.

Mr Giuliani is expected to appear in a Phoenix, Arizona courtroom for the arraignment hearing on Tuesday morning. He only received official notice of his indictment on Friday, when papers were served to him after his 80th birthday party.
