But they had begun an investigation of Burisma which was stopped when Joe Biden threatened to withhold U.S. government funds from Ukraine if the prosecutor investigating Burisma was not fired. And to quote Joe Biden in his bragging video, "... son of a bitch, he was fired." Burisma is the energy company in Ukraine where Hunter Biden was on the board of directors while Joe Biden was VP and had been assigned by Barack Obama to oversee operations in Ukraine. If you don't believe me watch the video of Biden on Youtube entitled, "Joe Biden Ukraine Video Bragging ".
