I saw he had done some long interview several months ago and it was getting a lot of positive responses even from conservatives. I never got around to watching it so can't judge for myself. Seen a number of funny responses by him on X though.
I don't know much about him other than that he was the boards of Ukrainian companies, obvious corruption it seemed. The companies owners obviously thought they could buy influence with the president through his son. However, while he made millions Trump's family made billions, benefiting from relations to the president. In no way is this excusing the Bidens' corruption. It's just interesting to note how one's sympathies often affect who you call out.
