WASHINGTON -- Supporters of President Donald Trump gathered in Washington, D.C., and other cities Saturday, a week after the presidential race was called for Democrat Joe Biden.
Trump supporters swarmed his motorcade in adulation when he detoured for a drive-by on his way out of town.
Their chants and cheers tracked Trump's own false claims that he, not Biden, actually won the Nov. 3 election.
The Washington protests were hit by sporadic violence later in the day as both sides taunted the other.
Videos posted on social media showed fistfights and people using projectiles and clubs.
By early evening, police had arrested at least 20, including four on firearms charges, and at least one stabbing was reported.
