Most news about Hunter Biden seems to be coming mostly from tabloids with a questionable relationship with the truth, and a political axe to grind. Even Fox News, a station known for its flexibility in what they call truth, passed on the story due to credibility concerns.
As far as I can tell, there's no convincing evidence that any of those questionable emails are authentic, and although a few of the emails do seem to be authentic, it's not clear that the hard disk itself is, and there's plenty of evidence that that hard disk has been messed with and has lots of content planted on it by others.
So everything about this smells like a dirty political hit job that even half of the Murdoch empire doesn't want anything to do with. And even if there is something here, it still pales in comparison to the corruption that Trump and his kids are still getting away with. Everything about this smells like a dirty political witch hunt based on made up or strongly manipulated "evidence".
