One person was stabbed and taken to a trauma center with critical injuries when supporters of President Donald Trump clashed with counter-protesters in Washington, D.C. on Saturday. Two officers also faced undisclosed injuries while 20 people were arrested in the mayhem, NBC Washington reported. Some were arrested for firearms violations, while others were booked for assaulting an officer, simple assault and disorderly conduct. 

The Trump supporters came together in downtown Washington, D.C. to protest the outcome of the 2020 presidential election, which was decided a week ago when president-elect Joe Biden and vice president Kamala Harris were declared as the winners.
