A man was arrested Thursday after he ran his car through protesters at Republican Rep. Ed Royce’s office in Brea, California.

Daniel Wenzek, a 56-year old Brea resident, was arrested on suspicion of a felony assault with a deadly weapon, according to the Orange County Register.

Wenzek’s motivation is still being investigated, Lt. Kelly Carpenter said.

Among the demonstrators outside the congressman’s office were people with Temporary Protected Status, which prevents them from being deported because of natural disaster or political conditions.

Recipients are calling for the Trump administration to extend the program.
