|He set out to create a mini-Goldman Sachs. In the end, he built a mini-Lehman Brothers.
Former New Jersey Gov. Jon Corzine's resignation Friday from the securities firm he led capped a week of high drama and swift failure.
MF Global collapsed into bankruptcy Monday, and Corzine has since hired a criminal defense attorney amid an FBI investigation into the disappearance of hundreds of millions of dollars in client money.
In another twist, a top regulator has ended his role in the investigation of MF Global because of his longstanding ties to Corzine. Commodity Futures Trading Commission chairman Gary Gensler, whose agency is leading the effort to locate the missing client money, had worked for Corzine at Goldman Sachs.
MF Global's implosion, which came after Corzine made a big, risky bet on European debt, revived memories of the 2008 banking crisis and the ruin of the much bigger Lehman.
