The Internal Revenue Service is required by federal law to keep records of all agency emails and to print out hard copies of the emails to make sure they get saved in the event of a computer glitch.

The IRS recently claimed that it lost 24,000 of 67,000 emails that ex-official Lois Lerner sent between 2009 and 2011, due to a computer crash. The IRS, which agreed to turn over all of Lerner’s emails to the House Committee on Ways and Means, specifically lost emails Lerner sent to other Obama administration agencies and the White House. Lerner is a major figure in the targeting scandal that has hit the IRS.
