Two more people are being charged in connection with a protest in Provo last month that turned violent. 

Prosecutors say 25-year-old John Sullivan of Sandy was part of a group called Insurgence USA and was seen threatening drivers and directing protesters to block intersections. 

Twenty-four-year-old Jacob Siolo of St. George was recorded on video throwing water bottles at oncoming cars, and hitting several vehicles with his fist while yelling at drivers. 

Two others have already been charged in connection with the protest.
