At the center of the transactions described in the government's fraud case against Goldman, Sachs & Co. is New York hedge fund operator John Paulson, whose firm made $15 billion in 2007 by betting that Americans would default on their home loans in droves... Ultimately, though, the biggest beneficiary of the transactions was Paulson & Co.
Goldman "knew of Paulson's involvement in the selection" of securities, Levin told reporters. "They knew Paulson was going short."
