Hmm. I didn't read it that way. What I gleaned from the statement was that Tenet was saying, rather, that his mistake was that his people did not finally insist upon taking it out. They had nothing to do with putting it in. So his mistake could not then logically cause Bush to use the faulty information--it only allowed Bush to use it.
First, CIA approved the President's State of the Union address before it was delivered. Second, I am responsible for the approval process in my Agency. And third, the President had every reason to believe that the text presented to him was sound. These 16 words should never have been included in the text written for the President.
That's a pretty personal admission, in my opinion.
