On the 24th of September 2019, House Speaker Nancy Pelosi announced the initiation of a formal impeachment inquiry into President Donald Trump. The inquiry was launched after an allegation by a whistle-blower that President Trump pressed Ukrainian President Volodymyr Zelensky and his government to investigate Hunter Biden, the son of former vice president and 2020 presidential candidate Joe Biden in what is deemed by the supporters of the inquiry to be an attempt to hurt Biden's bid for the presidency.
