There is a big difference between reporting news from a specific angle or with a bias, and completing fabricating facts.
When CNN or Fox News or the New York times, report on something, it can be trusted that the FACTS reported are probably true. They just report on things from a specific angle.
So if CNN for example, has 10 news items about Trump and 5 are negative, they will emphasize those, and perhaps only mention the positive ones in passing. FoxNews would probably do the opposite.
So this is not about calling Fake News to any news that is critical of you, like our buffoon-in-chief does. It's about recognizing that actual truthful facts can be reported with different biases and perspectives.
