There is no way to prove that he did it. He could have done it. Who is to say.
Joe did the same to get a prosecutor fired in Ukraine while VP and bragged about it. The prosecutor that was going after his son's company. He bragged about it, Trump wanted to look into it. I don't see a difference.
Yeah, Trump is trash, so is Joe and probably 90% of politicians and talking heads. The "ruling class" is complete and utter garbage.
