Jones is one of 16 fake Trump voters who signed the “unofficial certificate of electorate” as part of a plan to overthrow the Electoral College in the 2020 election.
Jones is currently running for lieutenant governor of Georgia against Democrat Charlie Bailey. Willis hosted a fundraiser for Bailey last month and donated to her main campaign earlier this year.
In his ruling, Fulton County Superior Court Judge Robert McBurney said Willis’ office may “examine witnesses about the senator’s role in the state’s various Republican party efforts to rehabilitate question the legitimacy of the election results. do is secure that evidence to build a case against the senator.”
“It’s a ‘What are you thinking’ moment,” McBurney said. “The optics are horrible.”
The Georgia Attorney General’s Board will select an alternate District Attorney’s Office who may interview Jones, in accordance with Georgia law.
Willis’ office and Jones’ spokesperson did not immediately respond to requests for comment.
Willis’ attorney had said in court papers that his political support for Bailey’s campaign did not constitute grounds for disqualification or a conflict of interest in grand jury oversight. Last week, Willis’ attorney pointed out that the district attorney’s political actions were fully within the law.
CNN previously reported that court documents filed last week revealed Willis advised that Trump’s 16 bogus voters could be charged in his investigation.
