At least five CIA personnel, including government contractors, were asked to sign a second non-disclosure agreement after the Benghazi terrorist attack, Fox News has learned.

While the three-page NDA, obtained by Fox News, does not contain specific references to the 2012 attack which killed four Americans, including Ambassador Chris Stevens, it does contain standard language that unauthorized disclosures could lead to “temporary loss of pay or termination” and “in some circumstances, constitute a criminal offense.”

Sources not authorized to speak on the record, given the sensitivity of this week’s closed-door testimony before the House Intelligence Committee, said the five CIA personnel did not feel pressure to sign the document. But they felt the request for a second non-disclosure agreement after the terrorist attack was odd and not standard practice because their original NDA’s were still in effect, and only some in the group were undergoing contract modifications that might require a new NDA.
