I see no need for an apology and no merit for any lawsuit. Each part of those sentences is a factual statement. No where is it said, "Then Governor Phil Bryant is an embezzler." Bryant is making his own assumptions there, because he knows what he did.
Wikipedia says, "The previous director of Mississippi's welfare agency, John Davis, who admitted to being involved and is currently working with authorities, was appointed by Phil Bryant. An attorney said, “John Davis knows of the extent of personal involvement of former Governor Bryant and Governor (Tate) Reeves and the massive waste of taxpayer money,” but said that Davis was under direction from the FBI to remain silent." (my emphasis)
Sounds like someone at the FBI is working the case. Could be some FPMITA prison in Bryant's future.
