Bush used the active voice about the 16 weasel words here: "Otherwise, I wouldn't have put it in the speech. I'm not interested in talking about intelligence unless it's cleared by the CIA. And as Director Tenet said, it was cleared by the CIA.''
For how and why the CIA's approval process "cleared" bad intelligence, see the Veteran Intelligence Professionals for Sanity's "Memorandum" to the President (go read) (copy) .
Garbage in, garbage out.
