By 1996, the NSA became aware of an Al Qaeda communications hub located in Sana'a, Yemen, thru their tap of Osama Bin Laden's satellite phone. 1,100 total calls are made on this phone. Adding up the above numbers means that the destination of over 100 calls is still unaccounted for. The use of this phone stops two months after the August 1998 embassy bombings in Africa. However, they hear about an important meeting to be hold with Al Qaeda leaders and affiliates in a condominium in Kuala Lumpur, Malaysia in January 2000. However, what the NSA and CIA didn't tell the FBI about, was that two men, Khalid al-Mihdhar and Nawaf al-Hazmi, were to enter the United States as both men possessed valid US Visa passports which were approved by a consulate in Riyadh, Saudi Arabia. The question is, what information had the NSA heard regarding their monitoring of Bin Laden's satellite phones and the house in Yemen?
