Katie Miller

Federal prosecutors in Boston have indicted John Anthony Proia III, 41, of Waltham, Massachusetts, on cyberstalking charges. The indictment does not name the alleged victim, but a person familiar with the matter confirmed she is Katie Miller, a conservative podcaster married to White House deputy chief of staff Stephen Miller. Prosecutors allege that between August 3 and September 23, Proia used multiple phone numbers to send more than 40 calls and texts to Miller using expletives and a "menacing tone," and also sent messages to her parents describing her husband in antisemitic and inflammatory terms. The FBI's Joint Terrorism Task Force made the arrest, and Proia was released after an initial federal court appearance.

Attorney General Todd Blanche publicly condemned the conduct, and Katie Miller thanked him for the response. US Attorney Leah Foley said the defendant "repeatedly and relentlessly" targeted the victim and her family with "deeply disturbing communications" that "profoundly disrupted their lives." The case drew additional scrutiny after two FBI counterterrorism officials were demoted over handling of the investigation.

Federal prosecutors have charged John Anthony Proia III, 41, of Massachusetts, with cyberstalking conservative podcaster and former Trump administration official Katie Miller. Court papers allege Proia contacted Miller at least 40 times over several weeks, leaving menacing voicemails and text messages about her and her husband, White House Deputy Chief of Staff Stephen Miller, and also contacting her parents. He was arrested Thursday on one count of cyberstalking; an attorney for him has not responded to requests for comment.

U.S. Attorney for Massachusetts Leah Foley said those who use technology to harass or intimidate others will be held accountable. The investigation has also stirred turmoil within the FBI's Washington field office, where two senior counterterrorism supervisors were recently reassigned amid dissatisfaction over their handling of the case. The office's assistant director, Darren Cox, said the reassignments were a routine personnel decision unrelated to any directive from FBI Director Kash Patel.
