Massachusetts Man Arrested for Alleged Cyberstalking of Katie Miller

A Massachusetts man has been arrested and charged with cyberstalking Katie Miller, the wife of White House Deputy Chief of Staff for Policy Stephen Miller. John Anthony Proia III, 41, of Waltham, was charged Thursday with cyberstalking a "former political advisor and prominent member of the Republican Party" who is married to a "high-level federal government employee."

The FBI announced the charges, which were filed in federal district court in Boston. While the indictment does not name the Millers, sources confirmed to CBS News that they are the victims.

According to the indictment, Proia allegedly sent Katie Miller more than 40 calls and texts between August and September, some of which were sent late at night. He also is accused of contacting Miller's mother and father, leaving them disturbing text messages. In one message to Miller's mother, prosecutors stated Proia asked, "Does it disturb you that such evil as [Stephen Miller] is married to the creature that slithered from your c***?" In another, he allegedly referred to Katie Miller's father by name and said, "hope your daughter marrying a Jewish Nazi/white supremacist is working out for you."

Prosecutors added that Proia often used expletives and a "menacing tone" in his communications. He then allegedly employed an internet-based phone system to hide his identity and change his phone number.

"Cyberstalking can inflict real fear and harm, and we take these allegations extremely seriously," said US Attorney Leah Foley in a statement. "Those who use technology to harass, intimidate or torment others should understand that attempts to anonymize their criminal conduct will not shield them from prosecution. We will find you and we will hold you accountable."

Ted Docks, Special Agent in Charge of the FBI's Boston Division, stated, "Terrorizing someone isn't some sick game, it's a crime, which is why the FBI and our partners take it so seriously as we work to protect and serve everyone in our communities."

This arrest follows previous complaints by Katie Miller to law enforcement regarding alleged threats and harassment. Last year, she reported an incident where local activist Barbara Wien allegedly distributed flyers near the Millers' home in Arlington, Virginia. The flyers reportedly showed Stephen Miller on a "Wanted" poster for "crimes against humanity," included the couple's address, and provided a QR code urging viewers to demand a congressional investigation into his conduct. This incident prompted the Millers to move into military housing.

However, the federal investigation into the flyer incident stalled after a magistrate judge twice rejected a search warrant for Wien's phone. The state investigation also concluded earlier this year, with the Arlington and Falls Church Commonwealth Attorney stating that the evidence did not support criminal prosecution.

The current investigation into Proia's alleged cyberstalking comes after reports that the Millers had complained about the FBI's perceived lack of action, a situation that reportedly led to the demotion of two senior counterterrorism agents. Darren Cox, who leads the Washington Field Office, issued a statement asserting that he made the decision regarding the agents and not FBI Director Kash Patel.
