I have yet to see any definitive evidence that The Donald has knowingly and willfully engaged in money laundering. It's a sticky crime given the need for a third-party intermediary.
That's not to say that there aren't smoking guns all around. There are. But most of the evidence I see is based on guilt by association.
Yes, Donald has lied and twisted the truth that his business has relied on Russian money - especially after the 2008 financial melt-down.
Yes, there's Manafort in particular who clearly was up to his eyeballs in helping Putin.
Yes, Cypress banks, oligarchs buying his properties, the Donald's love of all things Putin, etc., but...
No, there is really only speculation at this point IMO as to whether The Donald is an international money launderer.
Ask yourself this: If The Donald were working with oligarchs illegally, wouldn't Putin and co. be holding the proverbial Sword of Damocles over his head? And wouldn't our intelligence agencies have already sniffed up at least a shred of chatter within their network? Hasn't happened to my knowledge.
Look, I think Donald is a dirtbag, and that he'd sell his Mom to the Barker next to the Tilt-o-Whirl for a stuffed animal, but I do not think our President is a money launderer.
