In July 2016, the State Department will reveal some limited details about 22 “top secret” emails involving Clinton. One email chain is sent sometime in 2012, and involves two “top secret” emails. The chain begins with an email written by an unnamed State Department official. It makes its way to Sullivan, who forwards it to Clinton and Clinton’s chief of staff Cheryl Mills. There is no known reply from Clinton. The content of the emails remain unknown. (Vice News, 7/22/2016)
