Trump Brags About Withholding Evidence as Democratic Impeachment Managers Lay Out Case in the Senate

During the opening day of oral arguments in the impeachment trial, President Trump was accused of abusing his office to "cheat an election." House impeachment managers spent about eight hours on Wednesday laying out their case for why President Trump should be removed from office. The Senate trial comes a month after the House impeached Trump for withholding congressionally approved military aid to Ukraine as part of an effort to pressure the Ukrainian president to investigate Trump's political rival, Democratic presidential candidate Joe Biden. While the impeachment trial was taking place in the Senate, President Trump was across the Atlantic at the World Economic Forum in Davos, where he tweeted more than 140 times and dismissed the impeachment trial as a hoax. Trump also appeared to boast about having withheld evidence from the impeachment process, saying, "We have all the material; they don't have the material."
