They wouldnt investigate them if they didnt have evidence. Rudy must have hit the jackpot.
I believe you are not far off target on this.
RG cut his teeth fighting organized crime in New York. Ukraine ain't that much different.
I think PDJT knows this and trust RG to go for the throat of organized crime such as what is going on with the Bidens, Obama and Her Thighness.
I believe RG has just scratched the surface so far in his quest for justice. Whatever it is a target rich environment out there.
