PHOENIX (AP) — Former Arizona Republican Party chair Kelli Ward and at least 11 other people are set to be arraigned Tuesday in a Phoenix courtroom on conspiracy, forgery and fraud charges stemming from their roles in an effort to overturn Donald Trump’s 2020 election loss in Arizona to Joe Biden.

Former New York Mayor Rudy Giuliani also is scheduled to be arraigned, though it’s unclear whether he’ll seek a postponement. Arizona authorities tried unsuccessfully over several weeks to serve Giuliani notice of the indictment against him. Giuliani was finally served Friday night as he was walking to a car after his 80th birthday celebration.

Arizona authorities unveiled the felony charges last month against Republicans who submitted a document to Congress falsely declaring Trump, a Republican, had won Arizona. The defendants include five lawyers connected to the former president and two former Trump aides. Biden, a Democrat, won Arizona by more than 10,000 votes.
