What do you do to insure that your source(s) are legitimate -- i.e. not "fake news" ? I try to corroborate using multiple sources for the same/similar story. Here is another (surely not the only) way : [newsguardtech.com]
Moderate news sites... Yes, they exist. WTOP radio in Wash DC does a very good job of just reporting the news. When there is slanted commentary they announce exactly what it is and that it is opinion.
Other than that... I need to see it with my own eyes or check multiple sources. The thing about the DC area is that all news is pretty much national news.
