Fulton County District Attorney Fani Willis’ case against Former President Donald Trump may be heading for the rocks after a lawsuit accused her of having a “clandestine” relationship with one of the prosecutors in the case.

The lawsuit, filed by former Trump 2020 campaign official Michael Roman, alleges that Willis and Nathan Wade —a private attorney with the Atlanta-based Wade & Campbell Firm— engaged in an improper relationship that has seen Wade profit significantly from prosecuting Roman and his co-defendant.

“Mr. Roman … moves the Court for an order disqualifying the district attorney, her office, and the special prosecutor from further prosecuting the instant matter on the grounds that the district attorney and the special prosecutor have been engaged in an improper, clandestine personal relationship during the pendency of this case, which has resulted in the special prosecutor, and, in turn, the district attorney, profiting significantly from this prosecution at the expense of the taxpayers,” the 127-page filing states.

Roman alleges Wade used some of the attorney fees Willis’ office paid him for working on Trump’s case to take the DA on lavish vacations to Napa Valley, California, Florida and the Caribbean. Roman argued that Willis and Wade should be disqualified from the case for violating Georgia Rules of Professional Conduct.

“Accordingly, the district attorney and the special prosecutor have violated laws regulating the use of public monies, suffer from irreparable conflicts of interest, and have violated their oaths of office under the Georgia Rules of Professional Conduct and should be disqualified from prosecuting this matter,” Roman’s lawsuit added.

Roman argued that Willi’s failure to disclose her relationship with Wade while paying him to work on the case with funds he spent on their lavish vacation amounts to honest service fraud.

Willis’ office paid Wade more than $600,000 to work on Trump’s case. The DA’s office indicted Trump, Roman and 16 other defendants under Georgia’s Racketeer Influenced and Corrupt Organizations (RICO) Act. The DA accused the defendants of allegedly trying to overturn Georgia’s 2020 presidential election result. Willis charged Roman with seven felony counts.
