He bragged at the dentist’s office about attending the Capitol riot, feds say. A patient turned him in.

After the patient “overheard Warmus talking about his experience while at a dentist’s office,” the person, who authorities said wished to remain anonymous, alerted the FBI and passed along Warmus’s phone number and home address. A mundane trip to the dentist’s office led to an investigation that concluded this week with Warmus, 37, in police custody.

Warmus was arrested Tuesday in Buffalo for his role in the Capitol riot, the Justice Department announced, joining more than 410 people who’ve been arrested since Jan. 6. He’s been charged with violent entry and disorderly conduct on Capitol grounds, knowingly entering or remaining in any restricted building without lawful authority and knowingly and with intent to impede or disrupt the disorderly conduct of government business.

Neither Warmus nor his father immediately responded to requests for comment Tuesday. It’s not clear whether Warmus has an attorney.

His arrest is the latest in what’s become a familiar trend in the past four months of the FBI getting information from just about anyone connected to boastful members of the pro-Trump mob – from family members and friends to colleagues and ex-girlfriends. Earlier this month, Robert Lee Petrosh was arrested after his mother shared the news of his presence at the Capitol to a friend of hers, which eventually resulted in the FBI’s involvement.

The Justice Department’s announcement came the same day that Albert Watkins, an attorney for Jacob Anthony Chansley, often referred to as the “QAnon Shaman,” said his client and many of the other accused Capitol rioters were vulnerable to believing the false claims of election fraud from former president Donald Trump. “These are people with brain damage,” Watkins told Talking Points Memo. “These aren’t bad people.”

Warmus joins more than 30 others from New York to be arrested in connection to the riot, according to an analysis by The Washington Post. He purportedly owns Worm-A-Fix Automotive Repair in nearby Orchard Park, N.Y., business records show. A message left for the business was not immediately returned.

Warmus, who made the nearly 300-mile trek from western New York in hope of overturning the election results, was seen wearing a Trump 2020 hat and sweatshirt that read, “CNN is fake news,” and waving a large flag with an expletive directed toward antifa, according to a nine-page statement of facts. Security footage shows that Warmus entered the Capitol at 2:17 p.m. on Jan. 6, authorities say, just minutes after rioters overwhelmed police officers attempting to block them from entering the building.
