The Justice and State departments are now citing a year-old FBI investigation and a future criminal prosecution to block access to survivors of last year’s Benghazi terror attack.

In an Oct. 28 letter to Sen. Lindsey Graham, R-S.C.,the State Department’s Assistant Secretary for Legislative Affairs, Julia Frifield, refers to “significant risks” and “serious concerns about having the survivors of the attack submit to additional interviews.”

Graham has been asking since last year for the FBI’s transcripts of interviews with State Department and CIA survivors who were evacuated to Germany after the Sep.11 attack on the U.S. consulate.

He and other Republicans believe the transcripts will show the survivors told the FBI it was a terrorist attack and made no mention of a video or anti-U.S. demonstration at the consulate.
