So, for all who follow Ukrainian politics closely…
Kolomoisky was the oligarch who funded Zelensky (also owns the TV station which made Zelensky famous).
Kolomoisky has been living in exile in Israel since 2016, when he had a falling out with Poroshenko, and his PrivatBank was nationalized (and a whole lotta money went missing).
Guiliani is hopping into this right after Zelensky’s election, I’m sure a total coincidence.
