There is currently a hot war for power happening between the government and the media. The MSM is telling Trump, "We are the real power. We control the nation."
Trump is telling them, "That may be true, but not on my watch."
This 'war' can be seen most clearly on the show Morning Joe. This show is basically the front-line of this struggle.
Trump is just knocking their out of control egos down a notch or two. Nothing sinister here. This is all just part of the struggle for dominance and power between Trump and the media. In my opinion, of the two sides, I would rather have government running the country than have the media in charge.
