The CIA just declassified 71 Presidential Daily Briefs spanning 1998 through September 2001 on the anniversary of 9/11
One of the documents, dated December 4, 1998, warned President Clinton that Bin Laden and his allies were preparing attacks inside the United States, including aircraft hijackings. It said operatives had already done a trial run and evaded security at a New York airport.
Members of the network had received hijack training. Another 1998 brief was titled “Reports That Bin Laden is Planning Attacks Inside the US.” The well-known August 6, 2001 PDB “Bin Laden Determined To Strike in US” came more than a month before the attacks.
Bill Clinton knew and did nothing.
