Outgoing FBI Director Robert Mueller made a startling claim yesterday to a Congressional Committee overseeing the NSA inquiry. The Director described how Khalid al-Midhar, one of the 9-11 hijackers, had called a Yemeni safe house from a phone in San Diego shortly before the attack. Mueller claims had today's surveillance system been in place, NSA surveillance of that call would have led to sharing of intelligence with the FBI and "derailed" the 9/11 attack. https://www.guardian.co.uk/…
That isn't the complete truth, however. Court records from the trial of convicted co-conspiractor Zakaria Moussaoui shows the FBI was aware of NSA intercepts of Midhar and and his partner Nawaf al-Hazmi in the months leading up to 9/11, who went on to hijack Flt. 77 that slammed into the Pentagon. The pair had also met with the other principal 9/11 hijackers at various locations inside the US. Based in part on NSA wiretaps that were later withheld and suppressed, FBI agents had, in fact, located the pair inside the US in mid-2001, but the investigating agents were ordered to close the file after CIA refused to cooperate and pressured the Bureau to shut down several lines of field investigation that were focusing on the plotters.

We've learned a great deal about 9/11 that confirmed earlier information that points to sabotage of FBI field investigations of the 9/11 hijackers known by both CIA and FBI to be inside the U.S.
