Fox News reports that the CIA moved swiftly to secure and close down its Benghazi annex following the 9-11-2012 attacks. From the story:
Within eight hours of the initial attack on the United States' diplomatic facility in Benghazi, Libya, the CIA decided to scrub and abandon rather than protect its annex, a military intelligence source told Fox News.
. . . The adjoining U.S. consulate, by contrast, has never been secured, even three months after the attack.
. . . As recently as Nov. 1, six weeks after the terrorist attack and nearly a month after an FBI team briefly collected evidence there, Foreign Policy magazine reported its journalists had found sensitive documents at the consulate, which included unsent memos about “troubling” surveillance by Libyan security guards.
