Impeachment inquiry into Donald Trump

The inquiry process which preceded the first impeachment of Donald Trump, 45th president of the United States, was initiated by then-House Speaker Nancy Pelosi on September 24, 2019, after a whistleblower alleged that Donald Trump may have abused the power of the presidency. Trump was accused of withholding military aid as a means of pressuring newly elected president of Ukraine Volodymyr Zelenskyy to pursue investigations of Joe Biden and his son Hunter and to investigate a conspiracy theory that Ukraine, not Russia, was behind interference in the 2016 presidential election.
