impeachment hearings
An impeachment inquiry against Donald Trump began after news that U.S. president Donald Trump and other top government officials pressured the leaders of Ukraine and other foreign nations to publicly announce investigations of former U.S. vice president and leading 2020 Democratic presidential candidate Joe Biden and his son Hunter[1][2] and released evidence supporting a fringe theory that Ukraine interfered in the 2016 U.S. election.
