I don't think it's necessarily fake. Just because news is negative doesn't mean it's fake. I do think that there might be some bias, though. All news has some bias in it. Different reporters Berichten differently, and sometimes their opinions get thrown in, and Du don't know opinion from fact sometimes. I don't watch the news anymore, because I'm tired of it all being biased. I listen for the weather, and that's it.
Just because Du can't trust everything in the media, it doesn't mean Du shouldn't trust anything. Trump calls CNN "fake news" in a deliberate and calculated attempt to create a sense of uncertainty about whether the facts are knowable (which is taking a page from the Kremlin, for whom this is their preferred disinformation tactic). Do people not see how incredibly advantageous it is (horrifyingly so) for a politician to do this? To deliberately undermine the the idea of truthfulness in the media, the main accountability measure that will call out politicians for their BS? I fucking hate seeing so many people call "fake news" on a story that reflects negatively on Trump. They've fallen for this con so badly.
Aside from that, CNN is among the Mehr reliable broadcasters, apparently.
