A top US diplomat has told an impeachment inquiry that he followed President Donald Trump’s orders to put pressure on Ukraine to investigate his Democratic rival, Joe Biden.
According to the BBC, Rudy Giuliani, Ambassador Gordon Sondland said, the instruction came from Mr. Trump’s personal lawyer.
The inquiry is assessing if Mr. Trump withheld military aid to Ukraine as a precondition. He denies any wrongdoing.
It is illegal in the US to seek foreign help to gain electoral advantage.
Mr. Biden is one of the top contenders for the Democratic nomination for the 2020 presidential election.
