The CIA tells President Bush that co-operation between the CIA and Saudi Arabia’s GID intelligence agency has enabled the US to penetrate al-Qaeda, according to a later account by investigative reporters Joe and Susan Trento. They will write: “The great secret of why the president and his team were complacent about warnings of an impending 9/11 attack in the summer of 2001 is that the CIA had assured the national command authority that the CIA’s cooperative arrangement with Saudi intelligence had resulted in the penetration of al-Qaeda at the highest levels, according to intelligence sources who worked in this area for both the Saudi and US services.” This may be a reference to 9/11 hijackers Nawaf Alhazmi and Khalid Almihdhar, who the Trentos claim are Saudi intelligence agents (see August 6, 2003).
