Moore implicates the White House in allowing relatives of Osama bin Laden to leave the United States without being interviewed at length by the FBI. In his narration in the movie, Moore states that "At least six private jets and nearly two dozen commercial planes carried the Saudis and the Bin Ladens out of the U.S. after September 13." Moore based this statement on the research of Craig Unger, author of "House of Bush, House of Saud", whom he interviewed for the film. Passenger lists can be found at the House of Bush website.
