@fox5dc: Secret Service Police and National Guard personnel responded just before 10 a.m. to the north side of Lafayette Park at 16th Street and H Street NW, where a vehicle had crashed onto the sidewalk. Officials said the driver became combative with law enforcement before being quickly taken into custody. D.C. police were called to sweep the vehicle as a precaution. Authorities closed roads surrounding Lafayette Park in response. ⠀ Around the same time, a second person allegedly jumped a barricade near the northwest corner of Lafayette Park. Officers quickly placed that individual under arrest as well. Both incidents remain under investigation.
