◼ Today marks six months since the September 11, 2012 terrorist attacks on the U.S. compounds in Benghazi, Libya in which four Americans were killed, including U.S. Ambassador Christopher Stevens. - Sharyl Attkisson/CBS
Some watchdog groups, members of the media and Republican members of Congress are asking: Where are the more than two dozen U.S. personnel who survived the attack but haven't been seen nor heard from in public since? There were also an undisclosed number of witnesses at the U.S. compounds in Tripoli but they also have not spoken publicly.
In a recent press report, Secretary of State John Kerry said he visited one survivor at "Bethesda hospital," and referred to him a "remarkably courageous person who is doing very, very well." Kerry added, "I've called his wife and talked to her." But the identities, condition and testimony of the survivors and witnesses have been closely held from the public.
