Robert Khuzami, the director of enforcement at the Securities & Exchange Commission, announced the SEC's enforcement action against Goldman last year with much fanfare, accusing Goldman of misleading investors in a mortgage-linked financial product, but in the end Goldman settled the case for $550 million. Senator Carl Levin grilled Goldman Sachs executives and referred testimony from the Congressional hearing to the Department of Justice for possible perjury charges, but nothing has come of it.
