The FBI is in possession of 80,000 files detailing possible support for the 9/11 hijackers received from a Saudi family, a new report states, while a former 9/11 Commission member says there is a strong link between the Saudis and the terrorist attacks.

The FBI files are related to an investigation of a Saudi family living in Sarasota, Florida that “suddenly vanished” about two weeks before 9/11, the Daily Beast reported.
