...while downplaying the dirty deals that Hunter and Joe were cooking up.

What dirty deals was Joe cooking up? This is whistleblower testimony, and so far none of it (to my knowledge) has soiled Joe. It does further paint Hunter as a con-man, trying to give the illusion of access for business. But, so far, no actual access has been testified to. And that's the whistleblower that was supposed to bring down the Biden family.

I'm open to believing any politician can be shady/crooked. I think it's something about the mental make-up of someone who would seek public office and power (e.g. I have no interest, but if I were in office I would be a straight arrow, even if it cost me friends and influence). But so far this testimony isn't proving that about Joe. So far. I don't know if the testimony is finished, or what future testimony may reveal.
