Who said this?

Quote.

Well, why, all of a sudden, if he had all these grave concerns, did he not raise these sooner? This is one-and-a-half years after he left the administration. And now, all of a sudden, he's raising these grave concerns that he claims he had. And I think you have to look at some of the facts. One, he is bringing this up in the heat of a presidential campaign. He has written a book and he certainly wants to go out there and promote that book.

The answer is Scott McClellan, reacting to Richard Clarke's book in 2004.
