The Pittsburgh Post-Gazette investigates the money-laundering destruction that Ukrainian billionaire oligarch Ihor Kolomoisky brought to America with some of the $5.5 billion allegedly stolen from his former PrivatBank in Ukraine. Kolomoisky faces multiple civil lawsuits and criminal investigations, but thus far has not be charged with any crime. On March 5, the U.S. sanctioned Kolomoisky for “significant corruption” and banned him from the US.
