Authorities are investigating after a press box and maintenance building at a football field in Racine was set on fire.
The Boone County Sheriff's Office believes that the person or people responsible for the fire also wrote the phrase "Trump Train" in paint on the field.
Local news organizations report that Sunday's fire destroyed equipment used by the Seth Midget Football League. Officials from the youth football league say that an estimated $15,000 worth of equipment was destroyed.
League president Jeremy Johnson says organizers had collected the equipment over a three-year period. The items included football helmets, padded football pants and field equipment.
Anyone with information is asked to contact authorities.
