Man charged with cyberstalking Katie Miller

A Massachusetts man was arrested Thursday and charged with cyberstalking conservative podcaster Katie Miller, the wife of White House deputy chief of staff Stephen Miller, after prosecutors alleged that he repeatedly called and texted her for weeks.

John Anthony Proia III, 41, was indicted on one count of cyberstalking over what prosecutors described as a weeks-long harassment campaign between Aug. 3 and Sept. 23, when he sent threatening messages and left numerous vulgar voicemails to Katie Miller, her husband and her parents.

According to the Justice Department, some of the messages sent to her parents described her husband as “evil” and a “Jewish Nazi/white supremacist.”

Court documents did not identify Miller by name and instead described the victim as a former political adviser and prominent Republican figure married to a high-ranking government official. Numerous outlets including The Associated Press cited sources briefed on the case that confirmed she was the alleged victim.

Proia, who comes from the Boston suburb Waltham, pleaded not guilty to the felony charge before a magistrate judge in an initial court appearance.

“As alleged in the Indictment, the defendant repeatedly and relentlessly targeted the victim, her husband and her family with deeply disturbing communications that profoundly disrupted their lives,” U.S. Attorney Leah Foley said 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,” she added.

Attorney General Todd Blanche also weighed in on the case Thursday, writing on the social platform X that the alleged conduct was “criminal and will be treated as it should — with prosecution!”

Miller shared her gratitude over the arrest and charges in a social media post .

“Thank you Todd Blanche, Leah Foley, and the FBI Washington Field Office for keeping me and my family safe,” she wrote. “Good to see a Boston grand jury indict this man.”
