No seriously. Why is Congress investigating a failed company? Historically, Congressional investigations have been politically motivated, as it is not the duty of the legislative branch of government to conduct investigations. There's no good reason Congress is pursuing this, other than the fact that the Democrats have successfully tied George W. Bush and energy companies together in the eyes of the public, and hope insinuate some sort of scandal on the part of the Bush administration by the boosting the news coverage of the collapse. Of course, such a link between Bush and the Enron collapse has yet to be proved, but insinuation is all that is needed to do damage.
