With a density reminiscent of Dan Rather, Kristoff more or less makes a correction

“First, he denies that he stated that the Vice President's office, not the
CIA, sent Ambassador Wilson to Niger, only that Cheney wanted an investigation
by somebody. But Kristof admits: 'In fairness, though, it is true that Cheney
apparently didn't know that Wilson had been dispatched. If I'd known that I
would have said so.'

"Then he turns to the matter of his column reporting that Wilson had
actually seen (forged) documents on the uranium deal, when he didn't. Kristof
explains: 'Wilson has said that he misspoke when he made references to the
documents to me and to two other journalists.'

“'But it does seem to be true that Wilson claims to have debunked the Niger
deal more firmly than some people remember him debunking it.'”

Translation – Wilson debunked nothing. Close enough, though, for the NYTimes.
