The White House is quietly working to undercut a key post-Enron reform, significantly weakening protection for everyday investors and threatening the administration's image as a champion for financial regulatory reform. White House Chief of Staff Rahm Emanuel has been telling Democratic members of the House Financial Services Committee that he supports amending the Investor Protection Act of 2009 -- a bill designed to beef up protection for investors -- in order to exempt small businesses from a requirement in the Sarbanes-Oxley Act that mandates audits of internal controls. The Sarbanes-Oxley Act was enacted in 2002 in the wake of accounting scandals at Enron and Worldcom that rocked investors and damaged confidence in the markets.
