FILE - This May 22, 2013 file photo shows Internal Revenue Service (IRS) official Lois Lerner on Capitol Hill in Washington. The IRS says it has lost a trove of emails to and from a central figure in the agency's tea party controversy. The IRS told congressional investigators Friday it cannot locate many of Lois Lerner's emails prior to 2011 because her computer crashed that year. Lerner headed the IRS division that processed applications for tax-exempt status. The IRS acknowledged last year that agents had improperly scrutinized applications for tax-exempt status by tea party and other conservative groups. The IRS was able to generate 24,000 Lerner emails from 2009 to 2011 because Lerner had copied in other IRS employees. But an untold number are gone. (AP Photo/J. Scott Applewhite, File)
