It's not a conspiracy. You can have emergent bias as much as planned bias. That's basically the position of various HR departments who offer unconscious bias training.
At any rate, every study I've seen has confirmed that most media orgs at least lean left. Have you seen any that disagree?
For example, I've noticed that a lot of Americans think of Angela Merkel as a leftist. But she's a right-wing conservative from a party called "Christian Democratic Union"!
In a way, the American media has been successfully gerrymandered: the extreme right has been pulling the left/right demarcation line towards them for decades.
So things that seem rather moderate to a European (nationalising some industry) is a brand new thing in the American context.
There are also complexities in that America doesn't really have a clearly defined racial, religious, or ethnic identity. The common identity in America mostly centers around ideas and individual rights, so the American right has much more interest in liberty, relatively, compared to the European right.
When was the last time an entire industry was nationalized in Europe? I can't even think of a post-WWII example off the top of my head. (I'm sure there are examples, considering the success of Communist parties in some West European countries in the decade after 1945.)
It's true that there are more state-owned corporations in Europe... But some of the largest American corporations are so intricately tied to government deals and lobbying that there's no practical difference. I'm thinking of Lockheed, etc.
Compare Airbus and Boeing. One started as a multinational state-owned consortium created by European governments; the other has always been a private company. But they've ended up in basically the same position -- public corporations propped up by deep government subsidies in various disguises.
American and European capitalism isn't very different at all. Individual liberties are essentially the same with some tweaks. We're much closer than many think.
In the healthcare debate, the American right argued that the national government didn't (and shouldn't) have the power to take certain steps. The European right mostly argues from practical or identity-based reasons. So healthcare controversies involve levels of funding, pay for workers, coverage for refugees, and things like that.
So Scalia agreed that you're allowed to burn a flag in America. That's great -- but how did this ever even become a Supreme Court case? If you burn a flag in Sweden or France, nobody would think to sue you. The fact that this freedom had to be weighed at the highest possible level shows that Americans have serious blind points around their perception of freedom. Similarly, European countries have individual historical taboos on speech, such as the ban on Nazi symbols in Germany.
In the US healthcare debate, the right's constitutional argument seems to revolve around Obamacare's individual mandate -- but that's just is a clumsy artifact of how the system was overlaid on existing pseudo-private healthcare systems. With a properly designed tax-funded public healthcare system, the problem would go away.
1) Links to studies?
2) Having a leaning in op-eds doesn't mean a bias in facts reported. I'd assume if you have 0 bias there would be no point in lying about facts, but regardless of left-leaning or right-leaning organisations, the real issue is whether you present truth or not.

There are plenty more if you Google around. And they go back way before Trump was on the scene.
I'd be interested to see studies that dispute these findings. I haven't seen any.
A fair reporting of Trump comes across in a very bad light. I guess that's unfortunate for him, but it's of his own making.
The real question is whether anything reported on him (or the right at large) are erroneous, as he has claimed hundreds of times ("lies" and "fake" specifically), because the very few times it has happened, it was publicly retracted, and most often people got fired for it. I think that's a marker for healthy news.

May I suggest that it's not causation?
