Noah Feldman Opening Statement
President Trump has committed impeachable high crimes and misdemeanors by corruptly abusing the office of the presidency. Specifically, President Trump abused his office by corruptly soliciting President Volodymyr Zelensky to announce investigations of his political rivals in order to gain personal advantage, including in the 2020 presidential election.
