U.S. Rep. Barney Frank (D-MA) holds a House Financial Services Committee hearing to address why a crisis originating from risky loans to less creditworthy buyers happened, on Capitol Hill in Washington, September 5, 2007. "What we have is a severe lack of investor confidence," said Frank, who also lashed out at the Fed for spurning an invitation to testify at Wednesday's hearing. REUTERS/Jonathan Ernst (UNITED STATES)
