Specifically, Commissioner Koskinen violated the public trust in the following ways:

Failed to comply with a subpoena resulting in destruction of key evidence.  Commissioner Koskinen failed to locate and preserve IRS records in accordance with a congressional subpoena and an internal preservation order.  The IRS erased 422 backup tapes containing as many as 24,000 of Lois Lerner’s emails – key pieces of evidence that were destroyed on Koskinen’s watch. 

Failed to testify truthfully and provided false and misleading information.  Commissioner Koskinen testified the IRS turned over all emails relevant to the congressional investigation, including all of Ms. Lerner’s emails.  When the agency determined Ms. Lerner’s emails were missing, Commissioner Koskinen testified the emails were unrecoverable.  These statements were false.

Failed to notify Congress that key evidence was missing.  The IRS knew Lois Lerner’s emails were missing in February 2014.  In fact, they were not missing; the IRS destroyed the emails on March 4, 2014.  The IRS did not notify Congress the emails were missing until June 2014 – four months later, and well after the White House and the Treasury Department were notified.
