That's both false and irrelevant. The Administration has never said that Saddam or Iraq had nothing to do with 9/11. What they've said is that there is no concrete evidence linking the two. Absence of evidence does not equal evidence of absence. They've made that exact point so many times its like a broken record. Yet still, people get it wrong.
Moreover, the CIA memo does not claim that Iraq had something to do with 9/11. It does say that Iraq had something to do with Al Qaeda. That's significant because contact between Iraq and Al Qaeda refutes the argument that Iraq and Al Qaeda would never work together.
"We have no evidence that Saddam Hussein was involved with the 11 September attacks "
President Bush
Which CIA memo? The Feith Memo, I have read, is related to the Office of Special Plans not the CIA. The CIA has for many months criticized the way intelligence reports were handled by the OSP.
