Knowing and having evidence are not the same.
Rudy made several trips to Ukraine but I’m sad to say, apparently obtained no evidence. Burisma was the lead corporate entity that received the money. We can say with certainty that the money was dissipated paying invoices of numerous corporations, that in turn paid invoices falling due etc, all of which are located out of the USA
Where the money was gathered is untraceable and unknown. The result is that there was no evidence and thus no crime
Yes, Rudy was on the trail and like Trump had to be reliant on many people’s cooperation and support for his efforts to succeed. Like the election fraud, IMO there is so much more going on that accounts for Ukraine being on our radar (even back when Pailin got grief for talking about it). If it weren’t for dems fear of Trump and conservative accountability coming back to Washington, I doubt what Biden’s people are doing with Ukraine would be happening now. I think it’s a giant coverup operation.
