Rep. Frank Wolf, R-VA,  said sources told him that survivors of the Benghazi terrorist attack have been asked to sign non-disclosure agreements and now the Virginia congressman is demanding to know who else was forced to sign the documents.

“According to trusted sources that have contacted my office, many, if not all, of the survivors of the Benghazi attacks – along with others at the Department of Defense and CIA – have been asked or directed to sign additional Non-Disclosure Agreements about their involvement in the Benghazi attacks,” Wolf said on the House floor. “Some of these “new” NDAs, as they call them, I have been told, were signed as recently as this summer.”

The congressman expressed grave concerns that federal workers might have been coerced into silence.

Wolf also referenced a Marine Corps Times report that indicated a Marine colonel whose task force was responsible for special operations in northern and western Africa at the time of the attack is still on active duty. However, it was claimed the colonel was retired and therefore could not be forced to testify before Congress.

“If these reports are accurate, this would be a stunning revelation to any member of Congress – any member of Congress that finds this out – and to the American people,” Wolf said. “It also raises serious concerns about the propriety of the administration’s efforts to silence those with knowledge of the Benghazi attack and response.”

Wolf is sending letters to the CIA, Defense Department and State Department asking for a list of all their personnel and contractors who were required to sign the non-disclosure agreements related to Benghazi.
