Fulton County District Attorney Fani Willis has been subpoenaed to testify in a colleague’s divorce proceeding, according to a court filing, a development that could shed light on claims Willis and the colleague carried out an improper romantic relationship as they prosecuted former President Donald Trump and others.

In a court filing reviewed by The Wall Street Journal, a process server said he showed up at Willis’s office in Atlanta on Monday morning with a subpoena seeking her testimony in the Cobb County divorce case of Nathan Wade, a lawyer she hired as a special prosecutor in the Trump case, and his wife, Joycelyn Wade. The process server said he left the subpoena, filed by Joycelyn Wade’s lawyer, with Willis’s executive assistant.

[Well, my my my! This makes it look as though Michael Roman’s attorneys actually did find out about a real and undisclosed affair between Willis and the special prosecutor she appointed — and paid nearly million dollars in legal fees to boot. Stay tuned; one of us will have more on this later. — Ed]
