We have access to global media these days. They are all reporting that the President lies on this or that, report the bizarre things he says or does, the dysfunction in the White House, the EOs, the phone calls, etc. It's the duty of news organizations to report news. It doesn't matter if Joe the Plumber says and does these things, but it's news when it's the President of the most powerful country in the world.
They do an excellent job, for the most part, IMO. The NYT, Washington Post, CNN, NBC, The Hill, etc.
Political talk shows are different. They usually present the host's point of view, with guests from the opposing side sometimes. They don't report news. They discuss the biggest issues of the day, as they see it. The point of those shows is to discuss issues that their viewers want to hear about. Their viewers share the host's viewpoint. So if there were two big stories that day, the host may mainly cover only the issue that his viewers consider more important to them. The very nature of such programs means that the opposing side will not be covered equally.
There are a few talk shows that do try to present both sides, like Morning Joe, Hardball, etc. They have guests on for long discussions who belong to different political parties and take different positions.
The comedy shows focus on Trump, since he's President (and let's face it...he gives them lots of material). They always focus on whoever is the President, from Gerald Ford falling down a lot to G W Bush saying "it wouldn't be prudent" to George W Bush saying "you misunderestimate me" to Obama's koolcat way of speaking. But Trump is so much funnier than the others.
