Fulton County District Attorney Fani Willis is accusing the estranged wife of a special prosecutor she hired of trying to obstruct her criminal election-interference case against former President Donald Trump and others by seeking to question her in the couple’s divorce proceedings.

A motion filed last week by a defense attorney in the election case alleges that Willis was involved in a romantic relationship with attorney Nathan Wade. A lawyer for Willis wrote in a filing Thursday that lawyers for Wade’s wife, Joycelyn Wade, served a subpoena to the district attorney last week.
