A Senate investigations panel looking into Goldman Sachs' role in the financial crisis subpoenaed the investment bank as early as June 30, 2009, long before securities regulators sued it for fraud, according to a congressional aide. The aide also said that the panel notified Goldman on April 5, eleven days before the action by the Securities and Exchange Commission, about who would be called as witnesses, including trader Fabrice Tourre, the only Goldman executive named as a defendant in the SEC lawsuit. The SEC has accused Goldman and Tourre of not giving investors "vital information" about a debt security created with input from Paulson & Co, a major hedge fund, which then shorted the security.
