One of Sayyaf's most significant mentions in the 2004 9/11 Commission Report (page 148) states:
"In January 1996, well aware that U.S. authorities were chasing him, [Khalid Sheikh Mohammed]
left Qatar for good and fled to Afghanistan, where he renewed his relationship with Rasul Sayyaf."
This confirms not only did Sayyaf employ, train and mentor Khalid Sheik Mohammed prior to his terrorist spree, Sayyaf maintained his relationship with KSM in the midst of his terrorist spree. And yet one of the first things the most senior CIA officer who deployed to Afghanistan first after 9/11 did was put Sayyaf on the CIA payroll. That CIA officer was Gary Schroen - he admits it shamelessly in his book 'First In' - saying he personally handed Sayyaf his first $100,000 CIA payment.
