PHOENIX — Former Donald Trump presidential chief of staff Mark Meadows and Trump 2020 Election Day operations director Michael Roman pleaded not guilty Friday in Phoenix to nine felony charges for their roles in an effort to overturn Trump’s Arizona election loss to Joe Biden.

Meadows and Roman appeared by videoconference for separate brief hearings before Maricopa County Superior Court Commissioner Shellie Smith, who set an Oct. 31 trial date.

The indictment says Meadows worked with other Trump campaign members to submit names of fake electors from Arizona and other states to Congress in a bid to keep Trump in office despite his November 2020 defeat at the ballot box.

The document alleges that 11 Arizona Republicans submitted paperwork falsely declaring that Trump won in Arizona. Biden won Arizona by more than 10,000 votes. The indictment also says Meadows confided to a White House staff member in early November 2020 that Trump had lost the election.

Roman is accused in the indictment of working closely with Trump lawyers Rudy Giuliani and Boris Epshteyn and others to organize the fake electors’ votes in Arizona and six other states.

Outside court, Roman’s attorney, Kurt Altman, promised to fight the charges.

“Mike Roman has no connection with Arizona. Why this indictment came in the first place is beyond us,” Altman told reporters. “But we’re going to face the reality and defend.”

Attorney Anne Chapman represented Meadows remotely during the hearing. She did not immediately return a phone call and email from The Associated Press seeking comment on her client’s behalf.

Giuliani, the former New York City mayor, pleaded not guilty in May to nine felony charges stemming from his role in the fake electors effort. The Arizona indictment includes felony charges against Trump attorneys John Eastman, Christina Bobb and Jenna Ellis.

Epshteyn, Ellis and James Lamon, another Republican who claimed Trump carried Arizona, are scheduled to enter pleas June 18.
