I heard it was our pro terrorist State Department -- not the CIA that kept denying the meeting. And as for proof, the diary of the Iraqi intelligence officer mentions the visit of a Hamburg student that day -- Atta!
That's plausible but from what I've read not been confirmed. The stronger proof is Yasin vamoosing back to Baghdad after the first 9/11 bombing. No one seems to pay attention to this glaring fact. Let's restate that: an Iraqi citizen was deeply connected to the first WTC radical/Islamo bombing and was given shelter in Baghdad by Hussein. And doubters wonder why some people believed Hussein was involved with the second bombing. Well it's because it was very logical to assume that he was involved. With the first and second bombings.
And again there is a lot of smoke concerning Iraqi agents meeting with Al-Qaeda. Even the 9/11 commission affirmed they had connections. So why is it so hard for many people to believe that Hussein might have been more deeply involved in 9/11?
