The fact that the State Department has been publicly complaining for years that the Prosecutor's office was not investigating Burisma's owner?

Feb. 3, 2015 — Obama administration conveys harsh criticism of Ukraine Prosecutor General’s Office for its coverup of Zlochevskiy/Burisma
George Kent, who was then-senior anti-corruption coordinator in the State Department’s European Bureau and was in Ukraine temporarily as acting deputy chief of mission at the U.S. Embassy in Kyiv, met with a deputy of Prosecutor General Yarema, according to his closed congressional testimony. Kent, who had long pushed Ukrainian prosecutors for investigations into Zlochevskiy, “scolded” the deputy prosecutor for having “shut the criminal case” that had been the basis for a U.K. court freezing Zlochevskiy’s assets, demanding, “Who took the bribe and how much was it?,” Kent asked. Kent’s effort was coordinated with the Justice Department.
