After four turbulent years under President Trump, President Biden took office on January 20, 2021 following a violent riot at the U.S. Capitol aimed at stopping the certification of electoral votes. The rioters believed false claims of widespread election fraud and that Trump had actually won reelection. Trump helped fuel the attempt to overturn the election results. Many in Congress now deny the legitimacy of the 2020 election results, threatening democracy in America and elsewhere.
