Sure, but I'd argue good journalism doesn't have much to do with having a bias. It's perfectly possible for somebody to write good investigative journalism while having a particular bias. So, it's not so much about the bias itself, but rather their ability to present the facts, to explain the relationships between the events, and to paint a broader context for the story.

What I think your actual concern might be is regarding deceptive reporting where people try to paint things as something other than what they really are.

If you are looking for stuff to financially support specifically, I think sites that handle leaks are probably your best bet. They always need money between all the legal shit and the infrastructure that requires.
