Genuinely thought this was some reference to something on the topic of 'fake news' Abbreviations are great if you're using the term multiple time. Not as an intro.

I also thought it was a reference to a manner of distinguishing genuine Cable News Network (CNN) screenshots from doctored ones divulged by “fake news” outlets.

I would find it more likely that it was a reference to determine if CNN was being objective and truthful.
