Republicans Defend Trump in Public Impeachment Hearings VOA News Republicans contended Wednesday that U.S. President Donald Trump did not improperly pressure Ukraine to investigate political rivals for political advantage, with Representative Devin Nunes declaring the accusations were based on "zero evidence" and that Democrats "made it up." At the urging of Trump, Republican lawmakers mounted a vigorous defense of the president's actions in dealing with Ukraine over several months, and they asserted that the Democrats' case for impeachment against Trump was nonexistent. Trump's political supporters on the House Intelligence Committee focused on the fact that the president released military aid that Ukraine wanted, without opening investigations of former U.S. Vice President Joe Biden, which Trump had urged Ukrainian President VolodymyrZelenskiyto undertake. The Democratic-led impeachment inquiry against Trump entered a new phase Wednesday as witnesses began testifying publicly after weeks of closed-door testimony.
