FILE - In this May 22, 2013 file photo, Internal Revenue Service official Lois Lerner walks out of a House Oversight Committee hearing after refusing to answer questions about the extra scrutiny the IRS gave Tea Party and other conservative groups that applied for tax-exempt status, on Capitol Hill in Washington. Her lawyer, William W. Taylor, follows at left. The House Ways and Means Committee voted Wednesday, April 9, 2014, to refer Lerner to the Justice Department for possible criminal prosecution in the agency's tea party controversy. On Thursday, the House Oversight Committee and its tenacious chairman, Darrell Issa, R-Calif., has scheduled a vote on whether to hold Lerner in contempt of Congress for not responding to questions at two Oversight hearings.
