A 19-year-old Wisconsin man admitted to setting GOP Rep. Glenn Grothman's leased district office on fire over his support for banning TikTok if its parent company doesn't sell the app to a U.S. company, according to the Fond du Lac Police Department.

The incident occurred shortly around 1 a.m. on Sunday after the popular app had gone dark, according to the police.

Fox News reported the police encountered the man after the fire was put out.

The man, who is from Menasha, admitted he started the fire "in response to recent talks of a TikTok ban."
