TALLAHASSEE -- Gov. Rick Scott’s chief of staff Steve MacNamara will be announcing his resignation, ending what has been a tumultuous week of news reports about his steering no-bid contracts to friends and interfering in staffing decisions throughout state government, sources close to the Scott administration said Saturday afternoon. He will be replaced by Jacksonville political consultant Adam Hollingsworth, who worked on Scott’s campaign and was chief of staff to former Jacksonville Mayor John Peyton, said sources. The move to bring in Hollingsworth had been discussed since February because MacNamara had planned to leave the post by the end of the year. MacNamara’s resignation could be effective as early as July 1, sources said.
