Supposedly Igor Kolomoisky bought that mansion for him. I actually do believe Zelensky was hired for this job and sold his soul to the devil because he is very wealthy now. Doing the bidding of the corrupt US, UK and EU is dangerous and costly. I am sure all these trips over there by RATs is to keep him on board and to keep him from coming apart over the pressure he is probably under. Who knows, that vermin like Biden and Pelosi would be ripe for blackmail and Zelensky probably has the goods on them.
I wouldn’t be at all surprised. There are a whole lot of smelly rats in this equation, both Russian and Ukrainian.
