The Brief: Fake news is information published or posted that is not truthful or factual. Labeling something as fake news is also a way for people to dismiss something they disagree with.

Fake news is information published or posted that is not truthful or factual. Labeling something as fake news is also a way for people to dismiss something they disagree with.
The Fake News is working overtime. Just reported that, despite the tremendous success we are having with the economy & all things else, 91% of the Network News about me is negative (Fake). Why do we work so hard in working with the media when it is corrupt? Take away credentials?
