If Popehat and the Volokh Conspiracy are the typical sources, I suspect it's a slip of the tongue or mind blown way out of proportion, not some sort of official CNN policy or report.

EDIT: Searching around, all I see are similar sources: Infowars, Breitbart, etc. Maybe he said it (and who knows what the context was), but I don't think see any evidence it was more than a gaff. Certainly I never heard it from them or anyone else.
