A co-defendant in former U.S. President Donald Trump's Georgia 2020 election interference case on Monday accused Fulton County District Attorney Fani Willis and the case's special prosecutor of engaging in "an improper, clandestine personal relationship."The accusation came in a filing by co-defendant Michael Roman, who is seeking to have his indictment dismissed.The document, citing sources, alleges a romantic relationship between Willis and the prosecutor, Nathan Wade, and says Willis contracted Wade without the required approval by the county.Sources close to both the special prosecutor and the district attorney have confirmed Willis and Wade had an ongoing, personal and romantic relationship during the pendency of Wade's divorce proceedings."The 127-page filing also alleges that the pair profited "significantly from this prosecution at the expense of the taxpayers," adding that Wade has been paid $653,881 as of December 2023.
