Senator: U.S. didn’t connect ‘dots’ before 9/11 (http://archives.cnn.com/2002/US/05/15/inv.fbi.terror/index.html), cnn.com, May 15, 2002

“…Senate Intelligence Committee Chairman Bob Graham, D-Florida, said the House and Senate intelligence panels will hold hearings soon about various memos and reports, including one dubbed the Phoenix document, written by an FBI agent last summer.

“..The memo, he said, cited “an unusual number of Arab students” taking flight lessons in Arizona and raised “the suspicion that they had been sent there in a coordinated plot by Osama bin Laden in order to learn the U.S. civil aviation procedures.”

Graham was asked whether this info would have averted the attacks:

“Well, it might have been if this had been seen in the context of other information, which indicated that there was a potential conspiracy to use commercial airliners as weapons of mass destruction.“

Graham said that lawmakers

“did not get a satisfactory answer” about why the memo did not prompt more FBI action and investigation.
