Obama administration officials now working on fixing and regulating the financial system were beneficiaries of several million dollars in pay from Wall Street and private equity companies, it has been revealed.

Financial disclosure forms show that prior to joining the government, Gene Sperling, a senior Treasury adviser, was paid $887,727 by Goldman Sachs and $158,000 for speeches to companies that included Stanford Group, the company run by Sir Allen Stanford, who has since been charged with fraud.
