Former CEO, MF Global Holdings LTD.
He ran Goldman Sachs Group Inc., served as a U.S. senator and was governor of New Jersey, although he failed to win re-election. Then, in about a year and a half at the helm of MF Global, Corzine, 65, drove the firm into bankruptcy by embracing increased trading risk. About $1.6 billion of brokerage customer money went missing in the process. Corzine hasn't been charged with any wrongdoing.
WHAT HE SAYS: "I did not instruct anyone to lend customer funds to MF Global or any of its affiliates, nor was I told that anyone had done so." - Corzine, testifying to Congress on Dec. 15.
