Maybe my wording is not that clear, but I am just responding to this part of the article where the source for the story is clearly mentioned as an anonymous source.:

But they underestimated such warnings,” the official, who spoke on condition of anonymity because he wasn’t authorized to discuss the content of sensitive intelligence discussions with the media, told The Associated Press.
