Jan. 13, 2021—In a culminating step to a series of developments unprecedented in U.S. politics in more than a century, outgoing U.S. president Donald Trump and his supporters engaged in a riot aimed at overturning the results of the 2020 presidential election. While Congress certified the outcome of the November vote next day, on Jan. 7, it is notable that more than 25% of members of the House and Senate, all Republicans, joined Trump’s challenge to his defeat at the polls, even after the rightist mob attack on the U.S. Capitol had been dispersed.
