Members of Congress investigating Internal Revenue Service harassment of conservative organizations got quite a shock a few days ago.
They had asked for email messages to and from Lois Lerner, the former head of the IRS division accused of the blatantly political action. Those messages might have contained evidence in the case.
IRS officials now claim that all of Lerner's emails for the period January 2009 to April 2011, to and from anyone outside the agency - including the White House - were lost in a 2011 computer crash. The hard drive that contained them was recycled.
How convenient. Lawmakers should launch a new probe, into the claimed crash itself.
