The document find comes after CNN last month obtained the journal of U.S. Ambassador to Libya Christopher Stevens, who was killed in the Sept. 11 attack on the compound. The State Department was outraged at the news outlet for reporting details in the journal about security concerns.
Other documents contained personal information regarding the Libyans providing security at the compound, and there were several itineraries showing the meetings Stevens was supposed to have with Libyan leaders during his visit.
FBI agents were sent to Libya to investigate the attack, but they have remained in Tripoli and not traveled to Benghazi due to security concerns.
