9/11 hijackers tied to Saudi government, Graham says in book.

WASHINGTON -- Two of the Sept. 11, 2001, hijackers had a support network in the United States that included agents of the Saudi government, and the Bush administration and FBI blocked a congressional investigation into that relationship, Senator Bob Graham wrote in a book to be released Tuesday.

The discovery of the financial backing of the two hijackers "would draw a direct line between the terrorists and the government of Saudi Arabia, and trigger an attempted coverup by the Bush administration," the Florida Democrat wrote.

And in Graham's book, "Intelligence Matters," obtained by The Miami Herald yesterday, he makes clear that some details of that financial support from Saudi Arabia were in the 27 pages of the congressional inquiry's final report that were blocked from release by the administration, despite the pleas of leaders of both parties on the House and Senate intelligence committees
