His re-election loss to Biden came amidst a series of international crises, including the COVID-19 pandemic and resulting recession, and protests and riots following the police killing of George Floyd. In the aftermath of the election, Trump repeatedly falsely claimed that widespread electoral fraud had occurred and that he had won the election. Although many resulting lawsuits were either dismissed or ruled against by numerous courts, he nevertheless urged his supporters on January 6, 2021, to march to the Capitol while a joint session of Congress was assembled there to count electoral votes and formalize Biden's victory, leading to hundreds storming the building and interrupting the electoral vote count; as a result, the House impeached Trump for incitement of insurrection on January 13, 2021, making him the only federal officeholder in American history to be impeached twice (the Senate would later acquit him for the second time on February 13, 2021).
