WASHINGTON — A former conservative organizer was sentenced Monday to 10 months of probation and a $2,500 fine for entering the U.S. Capitol Building on Jan. 6.

Brandon Prenzlin, formerly of Arlington, Virginia, appeared before U.S. District Judge Trevor McFadden on Monday for sentencing on one misdemeanor count of parading, demonstrating or picketing in a Capitol building. Prenzlin, a former grassroots organizer with the conservative advocacy group FreedomWorks, was arrested last September and pleaded guilty to the Class “B” misdemeanor charge in March.
