Two men, Mark Prichard and Patrick Diehl, were arrested for trespassing with one also facing a charge for allegedly making a threat at Arizona Republican Senator Jeff Flake’s Tucson, Arizona office, according to authorities.

They were arrested on charges of third-degree criminal trespass on Thursday per a statement by the Pima County Sheriff’s Department (PCSD).

Mark Prichard, 59, is the individual facing a charge of threats and intimidation, a misdemeanor.

According to a PCSD press release, “Staffers working at the office indicated one of the protesters had made comments referencing the shooting of Rep. Scalise, which prompted them to call the Sheriff’s Department as well as lock the office doors.”
