E-mail shows State Dep't rejecting Libyan embassy's request for plane in May

No one has yet to argue that the DC-3 would have definitively made a difference for the four Americans killed that night. The security team in question, after all, left Libya in August.

But the question – both for the State Department, which is conducting an internal investigation, and the House Oversight and Government Reform Committee, which is holding hearings next week – is whether officials in Washington, D.C., specifically at the State Department, were as aware as they should have been about the deteriorating security situation in Libya, and whether officials were doing everything they could to protect Americans in that country…

Shown the email uncovered by ABC News, a spokesman for the committee said the “document is consistent with what the Oversight Committee has been told by individuals who worked in Libya. Ambassador Stevens and the diplomatic mission in Libya made multiple security related requests that were turned down by Washington based officials. Security related transportation has been identified as one of the particular items where embassy personnel did not receive the support they sought.”
