WASHINGTON (AP) — Several thousand supporters of President Donald Trump in Washington protested election results and then hailed Trump’s passing motorcade before nighttime clashes with counterdemonstrators sparked fistfights, at least one stabbing and at least 20 arrests. Several other cities on Saturday also saw gatherings of Trump supporters unwilling to accept Democrat Joe Biden’s Electoral College and popular vote victory as legitimate. Cries of “Stop the Steal” and “Count Every Vote” continued in spite of a lack of evidence of voter fraud or other problems that could reverse the result. After night fell, the relatively peaceful demonstrations in Washington turned from tense to violent. Videos posted on social media showed fistfights, projectiles and clubs as Trump supporters clashed with those demanding they take their MAGA hats and banners and leave. The tensions extended to Sunday morning. A variety of charges, including assault and weapons possession, were filed against those arrested, officials said. Two police officers were injured and several firearms were recovered by police.
