House Oversight and Government Reform Committee chairman Rep. Darrell Issa subpoenaed Internal Revenue Service (IRS) commissioner John Koskinen to testify about Lois Lerner’s “lost” emails and claimed that federal law mandates that Lerner’s emails should have been preserved.

Issa subpoenaed Koskinen to testify at a 7 p.m. hearing next Monday, June 23. The IRS claimed late last week that 2011 emails exchanged between Lerner and other Obama administration departments including the White House were lost in a computer crash and could not be provided to House Ways and Means Committee investigators probing the IRS targeting scandal, as previously agreed. Koskinen also agreed to testify before the Ways and Means Committee next Tuesday, June 24.
