The top U.S. diplomat in Ukraine, Bill Taylor, appeared in front of members of the House Intelligence, Oversight and Foreign Affairs committees Tuesday as part of an impeachment inquiry into President Donald Trump.

Taylor told the committees that Trump directed officials to tie foreign aid to Ukraine to demands that the country open an investigation into the Biden family and the 2016 election. Taylor also said that U.S. Ambassador to the European Union Gordon Sondland told him that while Trump was not requesting a "quid pro quo," he insisted Ukrainian President Volodymyr Zelenskiy publicly announce investigations into the Bidens and matters relating to the 2016 presidential election.
