“The full story of the FBI’s investigation into Saudi links to the 9/11 attacks has remained largely untold. Even the code name of the case — Operation Encore — has never been published before. This account is based on interviews with more than 50 current and former investigators, intelligence officials and witnesses in the case. It also draws on some previously secret documents as well as on the voluminous public files of the bipartisan 9/11 Commission.” NYT Mag and ProPublica: Operation Encore and the Saudi Connection: A Secret History of the 9/11 Investigation.
