So far, there has been no evidence tying Trump to any of this. Any involvement of his, so far, has been as a private citizen and perfectly legal. So far. I would like to see an investigation of John Podesta, whose shenanigans in the Ukraine while he was tied to Hillary Clinton as Sec/State. I have also read comments about Mitch McConnell. He is a political prostitute who should, at the very least, be locked up for soliciting. Concerning another comment about Trump's taxes, he pays some of the sharpest tax attorneys and accountants in the world to take care of that. I seriously doubt anyone will find anything wrong on that score. At any rate, he is under no obligation to release them to public scrutiny any more than you or I.
