A New Jersey gym owner pleaded guilty Friday to assaulting a policeman in the January 6 attack on the US Capitol by supporters of then-president Donald Trump. Scott Fairlamb, who is 44 years old, faces up to just more than four years in prison for joining the attack, which sought to prevent Congress from certifying President Joe Biden’s defeat of Trump in the November 2020 election. In a hearing in Washington federal court on Friday, the former mixed martial arts fighter was the first out of hundreds charged in the attack to plead guilty to assaulting a police officer. Videos taken of the melee showed him shouting and blocking a police officer as he waved a collapsible baton. Fairlamb shouted to “patriots” to disarm the police and storm the building. A second man, Devlyn Thompson of Washington state, also pleaded guilty Friday to assaulting police on January 6.Thompson, 28, was among a group that threw objects at police and took their riot shields.
