Fitzgerald has sent one former governor, Chicago’s city clerk, corrupt lobbyists, political fundraisers, influence peddlers and precinct captains to federal prison. Fitzgerald is the same federal prosecutor who captured the national spotlight as the leader of Washington’s CIA leak investigation, which led to the obstruction conviction of I. Lewis “Scooter” Libby, Vice President Dick Cheney’s chief of staff. (AP Photo/Charles Rex Arbogast, File)
