Harry Markopolos, Madoff Whistleblower, Slams SEC for Ignoring Him

A former investment manager is prepared to tell a House hearing on Wednesday that the Securities and Exchange Commission ignored his repeated warnings about the dealings of the disgraced financier Bernard L. Madoff.

The manager, Harry Markopolos, asserts that he submitted warnings about Mr. Madoff since 2000 and he assails the agency for ignoring his warnings or brushing them aside. "Nothing was done," he declares, in what Dow Jones Newswires and Fox Business report is his prepared testimony.
