Embarrassing revelations about the bank’s dealings during the credit crisis will not make comfortable listening Pressure continued to mount on Goldman Sachs boss Lloyd Blankfein today as he prepared to face a potentially fractious grilling by lawmakers in Washington tomorrow. In a keenly awaited hearing to examine a $1bn (£647m) fraud case brought by US regulators , Blankfein will appear before a Senate committee alongside the bank’s chief financial officer, David Viniar, and a controversial London-based employee, Fabrice Tourre , to answer accusations of unethical and unlawful profiteering from the global economic meltdown. Goldman also faces a class action suit from investors.
