Taylor Jr. testifies before Congress that he had been told President Donald Trump would, to help his reelection chances, withhold military aid to Ukraine until that country publicly declared investigations would be launched into Burisma Holdings, a company that hired former Vice President Joe Biden's son Hunter, as well as Ukraine's alleged involvement in the 2016 U.S. presidential election.
