In addition to the prison time, Fond du Lac County Circuit Judge Tricia Walker sentenced 20-year-old Caiden Stachowicz to seven years of extended supervision, court records show.

Stachowicz, of Menasha, pleaded no contest to an arson charge in November. Prosecutors dropped burglary and property damage counts in exchange for Stachowicz’s no contest plea, which isn’t an admission of guilt but is treated as such for the purposes of sentencing.

Stachowicz’s attorney, Timothy Hogan, didn’t immediately respond to a message seeking comment.

According to a criminal complaint, a police officer responded to a fire outside Republican U.S. Rep. Glenn Grothman’s office in Fond du Lac, about 55 miles (90 kilometers) northwest of Milwaukee, at around 1 a.m. on Jan. 19, 2025, and saw Stachowicz standing nearby.

He told the officer that he started the fire because he doesn’t like Grothman, according to the complaint. He initially planned to break into the office and start the fire inside but he couldn’t break the window, so he poured gas on an electrical box behind the building and around the front of the building, lit a match and watched it burn, according to the complaint.

He said he wanted to burn down the office because the federal government was shutting down TikTok in violation of his constitutional rights and peace was not longer an option, the complaint states. He added that Grothman voted for the shutdown, but he didn’t want to hurt Grothman or anyone else.

Grothman voted for a bill in April 2024 that required TikTok’s China-based company, ByteDance, to sell its U.S. operation. The deadline was Jan. 19, 2025, but President Donald Trump has issued multiple executive orders prolonging it. TikTok finalized a deal two months ago to create an American version of of the social video platform. Trump praised the deal.

A spokesperson for Grothman’s congressional office didn’t immediately respond to a message seeking comment.
