Council, according to the Department of Justice, unlawfully entered the Capitol building, and, when stopped by law enforcement, pushed an officer.

The radicalization of Trump supporters from all walks of life became jarringly apparent this month when a phalanx of lawyers, nurses, police officers, real estate agents and stay-at-home parents found common cause — terrorizing lawmakers for not overturning the results of a presidential election — with conspiracy mongers and violent white supremacists. Amid the throngs were a university professor, a hairdresser, a school therapist, a CEO, a piano teacher, an Olympic gold-medalist swimmer and a state representative from West Virginia. A Frisco, Tex., woman, Jenna Ryan, flew to the rally from Texas on a private plane, and posted a video from the riot where she hawked her professional services: “Y’all know who to hire for your realtor,” she said. “Jenna Ryan for your realtor.” (She has been arrested.)
