"ABC News has obtained an internal State Department email from May 3, 2012, indicating that the State Department denied a request from the security team at the Embassy of Libya to retain a DC-3 airplane in the country to better conduct their duties.
Copied on the email was U.S. Ambassador Chris Stevens, who was killed in a terrorist attack on the diplomatic post in Benghazi, Libya, Sept. 11, 2012, along with three other Americans. That attack has prompted questions about whether the diplomatic personnel in that country were provided with adequate security support."
