Under Secretary of State for Management Patrick Kennedy sends a letter to David Kendall, Clinton’s personal lawyer. In December 2014, Clinton gave the State Department paper copies of the over 30,000 emails she turned over at that time. But now, Kennedy also asks for electronic copies of them all (which contain metadata and can be more easily searched). However, one email publicly released on May 22 is classified at the “secret” level, which is the middle classification level. The email was sent to Clinton on November 18, 2012, and has the subject heading “FYI- Report of arrests — possible Benghazi connection.”
Kennedy specifically asks Kendall to delete all electronic copies of that email and give the State Department any remaining hard copies of it. Presumably this is due to concerns that the email might not be properly secured and/or Kendall might not have the security clearance to possess it.
On June 15, Kendall responds that he has followed Kennedy’s instructions except that he has been ordered by the House Benghazi Committee to keep electronic copies of all of Clinton’s emails, so he did not delete that one “secret” email. (Judicial Watch, 9/15/2015)
