Yellen flouts Congress' demand for information in leak probe

``Yellen has told Rep. Jeb Hensarling, R-Texas, who heads the House Financial Services Committee, that she can't provide some documents sought by his subpoena because doing so could jeopardize a criminal investigation by the Justice Department and the Fed's watchdog inspector general... The move escalated a months-long battle between the Fed chair and the lawmaker over an alleged leak in 2012 of interest-rate information to a financial newsletter.''
