9/11 Commission member Jamie Gorelick is given access to the previously sacrosanct Presidential Daily Briefings (PDBs) from the Clinton and Bush administrations (see Early December 2003). Like commission chair Thomas Kean, Gorelick is struck by the general lack of information in the documents (see Early December 2003), but the thing that strikes her most about the PDBs is just how many warnings were given in the months preceding the 9/11 attacks. Details of the predicted terrorist attack were lacking—the US intelligence community did not know where or when the attacks would take place—but the message from the spring, summer, and fall of 2001 was clear: the US must be prepared for a massive assault either on one of its foreign allies or on itself. Gorelick later recalls the warnings say the anticipated attacks are “the worst thing [the US has] ever seen—an unprecedented threat.” The August 6, 2001 PDB (see August 6, 2001) contained warnings about specific threats to American targets, particularly “federal buildings in New York.” Gorelick, like everyone else in the Commission, has never seen the actual August 6 PDB, and she is shocked by the detail and the specificity of the warnings. The characterization of the warnings as “historical” (see May 16, 2002) is inexplicable, she thinks. [Shenon, 2008, pp. 221-222]
