A federal judge in Washington, D.C., has sentenced a California man to 20 years in prison for his role in the January 6, 2021, Capitol insurrection. Video shows David Nicholas Dempsey repeatedly struck Capitol police officers with a flag pole, metal crutch and pepper spray as a mob of Trump supporters, incited by the outgoing president, tried to push their way past police barricades to stop the certification of Joe Biden’s Electoral College victory. It’s the second-longest sentence handed down so far against a January 6 rioter.
