MSNBC’s Morning Joe has barred Trump counselor Kellyanne Conway from appearing on the program because she has become an unreliable source. CNN previously banned Conway, at least for one day, because of similar concerns about the veracity of her statements.

You may recall that Conway coined the phrase “alternative facts” and referred in one interview to the “Bowling Green massacre,” a fake event. She also recently said that Michael Flynn, the former national security adviser, had the full confidence of the president hours before he was fired.

Should other news organizations follow the lede of CNN and Morning Joe? At what point does a source’s information become so tainted that you stop using her as a source? And where, at what level in the administration, does such a ban stop? If the president of the United States continues to make false comments, for example, do you stop covering him?

We’re living in a topsy-turvy world in which belief has become truth and facts seem to have little or no meaning to a significant minority – if not majority – of this country. What does that mean for the future of democracy and our society?
