Secretary of State Hillary Clinton may have endangered national security by receiving classified documents on the private email account she used to conduct government business instead of an official State Department account.

“Reports in the Associated Press and the Washington Examiner reflect that Mrs. Clinton had control over her own server hosting official agency emails, which contained relevant documents responsive to congressional investigations into the terror attacks in Benghazi, Libya,” Daniel Epstein, executive director of the Cause of Action non-profit watchdog that often litigates on behalf of government transparency, told the Washington Examiner.
