Looks like this is a PREDICTION, not an actual news report. The article does not indicate any specific knowledge of CNN sources, not even as “background” or “deep background”..... so far it’s not a news report but wishful thinking. Hope it happens, but we will have to see.....
The only source is Drudge.
Zucker presumably would have let key staff members know and someone leaked to Drudge.
But, yes, just a Twitter comment at the moment.
