Richman said an indictment “is not evidence of anything.”
“It is a one-sided story presented to a group of people, with the accused being unable to respond,” he said.
Seth Weathers, Williams' ex-campaign manager, called the charges a “political witch hunt” last week and said they lacked merit. Richman previously made clear that Weathers’ comments did “not reflect my team’s position.”
Williams came in fifth place out of five candidates in the Republican gubernatorial primary in May. He waged a controversial campaign that featured several attention-grabbing stunts, his final being a "deportation bus." He frequently highlighted his status as the first state official to endorse Donald Trump for president, and he wasn't afraid to pick fights with Lt. Gov. Casey Cagle, then the frontrunner in the gubernatorial race.
He will likely remain a sitting member of the Georgia Senate until Jan. 14, when he’ll be succeeded by Republican Greg Dolezal. The body could reconvene to vote to expel Williams, but that is considered unlikely.
