Plus the article is a pile of stupid innuendo that conflates what Hillary did with Petraeus providing contemporaneously classified documents to his journalist fuckbuddy.

Hillary Clinton <hdr22@clintonemail.com>
show up in the email composition window, which certainly cannot be mistaken for a state department email...
