Former President Donald Trump’s campaign attorney Jenna Ellis, who worked closely with his personal attorney, Rudy Giuliani, will cooperate with Arizona prosecutors in exchange for charges being dropped against her in a fake electors case, the state attorney general’s office announced Monday.

Ellis has previously pleaded not guilty to fraud, forgery and conspiracy charges in the Arizona case. Seventeen other people charged in the case have pleaded not guilty to the felony charges — including Giuliani, Trump presidential chief of staff Mark Meadows and 11 Republicans who submitted a document to Congress falsely declaring Trump had won Arizona.

Eleven people who had been nominated to be Arizona’s Republican electors had met in Phoenix on Dec. 14, 2020, to sign a certificate saying they were “duly elected and qualified” electors and claimed Trump had carried the state in the 2020 election. President Joe Biden won Arizona by 10,457 votes.
