Opinion. What is FAKE NEWS?

What is FAKE NEWS? We see that thrown around a lot lately. To me I've seen some on Conservative channels, but the MSM has Conservative media beat hands down. MSNBC, CNN, VOX, Huffington, Media Matters. The list goes on and on.

Recently I saw a Journalist with OAN attacked cause she put it to the MSM.

In closing, what's fake news to you?
