According to the Florida Times-Union,
The resignation comes two days after Florida Law Enforcement officers interviewed Carroll about her involvement with Allied Veterans of the World, a non-profit that operates internet cafes in Florida.
Officials from Allied Veterans and Nelson Cuba, the president of the Jacksonville Florida Order of Police, were arrested on racketeering charges after an investigation by the IRS and Secret Service.
Carroll gave her resignation letter to Gov. Rick Scott Monday. It gives no details about the decision, but in a statement, Adam Hollingsworth, Scott’s chief-of-staff, said fallout from the Allied Veterans investigation spurred the resignation.
