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.
Portions of the State of the Union speech draft came to the CIA for comment shortly before the speech was given. Various parts were shared with cognizant elements of the Agency for review. Although the documents related to the alleged Niger-Iraqi uranium deal had not yet been determined to be forgeries, officials who were reviewing the draft remarks on uranium raised several concerns about the fragmentary nature of the intelligence with National Security Council colleagues. Some of the language was changed. From what we know now, Agency officials in the end concurred that the text in the speech was factually correct — i.e. that the British government report said that Iraq sought uranium from Africa. This should not have been the test for clearing a Presidential address. This did not rise to the level of certainty which should be required for Presidential speeches, and CIA should have ensured that it was removed.
