I think journalists should submit themselves to the same kind of public scrutiny as politicians. People like Don Lemon, Chris Cuomo, Sean Hannity, Wolf Blitzer, and Tucker Carlson should be getting grilled by other journalists and defending their decisions in press conferences, just like they expect politicians to. They're actually more politically powerful than most elected officials.

Those 4 people you mentioned are political commentators not journalists- in a sense you are correct that they are sort of like politicians but they represent only their viewers/haters and don't vote on policy.

You're right. But they're the public face of whoever actually makes decisions about what is covered, how much it's covered, and how it's framed. Look at the front page of Fox or CNN: there is no real distinction between "opinion" and "news". The "news" coverage inevitably has the same framing that the commentators then run with and make explicit.

Someone should be held accountable in the court of public discourse, as we have come to expect of politicians. It seems like the commentators are the ones who, at least in the presentation of the papers and networks, most "own" the coverage, and who can be the subject of public backlash.

Here is a transcript of Tucker Carlson being questioned by Glenn Greenwald of The Intercept: https://theintercept.com/2017/07/26/intercepted-podcast/

This discussion is a case-study on how to respectfully disagree.

(search for where Tucker Carlson says "Thanks, Glenn." in the transcript. Probably better to listen so it is clearer which text is actually exerpts from Carlson's show and which text is the actual interview)
