Ukraine's Chief Prosecutor Could Be Pivotal in Trump, Biden Standoff Henry Ridgwell KYIV, UKRAINE - Ukraine's new prosecutor general has only been in office since the end of August, but he will likely be central to the future course of any investigations relating to the impeachment proceedings against U.S. President Donald Trump and the conduct of his possible rival, Joe Biden, in the 2020 presidential election. Democrats say Trump tried to blackmail Ukraine to get it to investigate the business dealings of Biden's son, Hunter Biden, when he sat on the board of a Ukrainian energy company. Republicans deny the blackmail accusation and say there are legitimate questions that must be answered about the role of both Bidens in Ukrainian affairs. .
