Georgia prosecutors sought to knock down misconduct allegations against Fulton County District Attorney Fani Willis on Friday, calling her father to the witness stand to testify about his knowledge of her romantic relationship with the special prosecutor she hired to lead Donald Trump’s case.

On the second day of an extraordinary hearing that could result in Willis and her office being removed from the case against the former president, Willis’ father, John Clifford Floyd III, testified that he had not met special prosecutor Nathan Wade until last year and didn’t find out until weeks ago that they had been in a relationship. Defense attorneys have been trying to show that the romantic relationship existed before Willis hired Wade.
