Clinton associate Cody Shearer sends Clinton confidant Sid Blumenthal a clearly classified document in an email. The subject heading for the email is: “Sid – This is Classified.” There is no text, but a document is attached called “Washington,_DC_Itinerary_for_D.doc.” In 2011 at least, Shearer and Blumenthal were business partners.
This email will only come to light because the hacker nicknamed Guccifer will post a screenshot of it after breaking into Blumenthal’s email account in March 2013.
It is not known if Shearer sent Blumenthal other classified information or if Blumenthal forwarded any such information to Clinton. (Gawker, 3/31/2015) Blumenthal has no security clearance to receive classified information at the time.
