Ukrainian President Says 'No Blackmail' in Trump Call

Ukrainian President Volodymyr Zelenskiy has denied that his American counterpart, Donald Trump, tried to blackmail him. Claims that Trump requested a corruption investigation into Hunter Biden, son of Democrat Joe Biden – in return for military aid - are the subject of an impeachment inquiry in the United States. At a press conference lasting several hours Thursday, Zelenskiy said he didn't know military aid from the U.S. had been held up when he spoke with Trump by phone in July.
