In this Oct. 11, 2006 file photo, former U.S. Attorney Patrick Fitzgerald speaks at a news conference in Chicago. Fitzgerald, who recently resigned after 11 years as head of the U.S. Attorney's Office in Chicago to enter private practice, made a name for himself as one of the most tenacious and successful federal prosecutors in recent history by putting two former Illinois governors and dozens of their cronies behind bars. White House officials will name a replacement to Fitzgerald in the next several weeks from a list of four finalists for what is arguably Chicago's second most powerful job, next only to Rahm Emanuel's job as mayor.
