It is the approach America had for most of our existence. The first papers were extremely partisan. Even as the country was being founded. The paper in existence in the capitol was very pro-Adams, so Jefferson and Madison went out and started a paper that was anti Adams, anti Washington, and CO will live this, pro French Revolution.

I grew up in Columbus, IN, and the paper was The Republic. It was started in 1872 as The Columbus Republican. Any wonder what party it supported? Many papers from the 1800s carried Democrat or Republican in the name.
So party media has been around since the beginning. In the middle of the 20th century we tried to have a neutral press. It would be my preference. But it isn't like Nazi Germany is the example we have to follow. Now we have all sorts of Republican press and Democratic press. Fox is Republican press. NY Post, Washington Times, Breitbart.
The biggest difference between the two is Reagan's 11th commandment. Type the name "Cuomo" into Google and do a search. Stories are in the Times, Post, NBC, Newsweek, PBS. It is missing from CNN as far as I can tell, which sucks on their part. Having his brother on air means they should be more diligent not less.
As to the press covering his press conferences, again, flavor of the month. NY had more COVID than anywhere else by far. I am not going to look up the numbers, but at one time it may have had more cases than the rest of the country combined. I recall in late spring when Arizona was the epicenter watching one of their press conferences.
The mainstream press over covered Tiger's accident, which pushed everything else off of the top. They did the same with Kobe. Google Cuomo, just about everyone has it now.
