An activist group chided Sen. Marco Rubio’s, R-Fla., position on gun control by using three billboards, taking a page from the Oscar-nominated film “Three Billboards Outside Ebbings, Missouri.”

The billboards were driven through Miami and near Rubio’s office in Doral, Fla., criticizing the senator after a school shooting Wednesday in Lakeland, Fla., left 17 people dead, according to a report on CNN.
