In another Fox News exclusive, Catherine Herridge reports that according to two sources, “at least one of the emails on Hillary Clinton’s private server” contained highly sensitive reporting of human intelligence sources engaged in ongoing operations, known as “HCS-O” in the intelligence community. “This is the most sensitive category,” Herridge said, “because of the jeopardy to the source.”
Both sources are familiar with the intelligence community inspector general’s January 14 letter to Congress, advising the Oversight committees that intelligence beyond Top Secret — known as Special Access Program (SAP) — was identified in the Clinton emails, as well the supporting documents from the affected agencies that owned the information and have final say on classification.
According to a December 2013 policy document released by the Office of the Director of National Intelligence: “The HSC-0 compartment (Operations) is used to protect exceptionally fragile and unique IC (intelligence community) clandestine HUMINT operations and methods that are not intended for dissemination outside of the originating agency.”
It is not publicly known whether the information contained in the Clinton emails also revealed who the human source was, their nationality or affiliation.
Dan Maguire, former Special Operations strategic planner for Africom, told Fox News the disclosure of sensitive material impacts national security and exposes U.S. sources.
