Newly released emails from the State Department show Hillary Clinton discussing the idea of sending "private security experts" to arm the opposition in Libya. 

Fox News chief intelligence correspondent Catherine Herridge delved into the contents of the emails this morning.

An April 2011 message from longtime adviser Sidney Blumenthal to Clinton contains a private intelligence assessment on Libya. 

Clinton then forwarded the assessment to her deputy chief of staff with the message, "FYI. The idea of using private security experts to arm the opposition should be considered."

That line was redacted by the State Department, Herridge said. But when the New York Times previously released that email on May 18, it was not blacked out.

Another heavily-redacted email appears to show that then-House Intelligence Committee chairman Mike Rogers (R-Mich.) wanted to discuss the "weapons issue" with Clinton.

"An operation by private contractors to arm the Libyan opposition in 2011, before it was fully recognized by the international community, was not permissible. And on its face, critics say, further supports their allegations that there was some kind of off-the-books operation if not by the U.S., then by our allies," Herridge reported.
