On Capitol Hill, four top banking executives appeared Wednesday before a congressional panel investigating the causes of the financial meltdown. Goldman Sachs CEO Lloyd Blankfein told the Financial Crisis Inquiry Commission he had “felt good” about Goldman’s survival during the height of the meltdown and suggested its multi-billion-dollar taxpayer bailout perhaps wasn’t necessary. Commission chair Philip Angelides responded, “I’m troubled by your inability to accept the probability or certainty your firm would not have made it through the storm but for the vast array of federal assistance.”
