Massachusetts Man Indicted for Cyberstalking Podcaster Katie Miller
Federal prosecutors indict a Massachusetts man for cyberstalking podcaster Katie Miller, wife of White House official Stephen Miller, following FBI review.
POLICY WIRE — Washington, D.C. — Federal authorities indicted a Massachusetts man on Thursday on cyberstalking charges involving podcaster Katie Miller, according to the Justice Department and individuals familiar with the matter.
John Anthony Proia III, a 41-year-old resident of Waltham, faces charges for allegedly targeting a prominent Republican figure and former political advisor married to a high-level federal official through more than 40 phone calls and text messages between August and September of this year.
While Katie Miller was not immediately available for comment, she acknowledged the development on X by sharing a post from Attorney General Todd Blanche and expressing gratitude toward Blanche, Leah Foley, and the Washington Field Office.
The formal indictment arrives in the wake of recent personnel changes at the FBI’s Washington Field Office, where the inquiry into the alleged threats was handled. Two senior counterintelligence agents were removed from their roles last week after the Millers raised concerns that the bureau was not pursuing the harassment claims aggressively enough.
Bloomberg Law initially broke the news of the demotions, prompting Darren Cox, head of the Washington Field Office, to clarify in a statement that he initiated the personnel actions independently rather than under direction from FBI Director Kash Patel.
This marks at least the second occasion that Katie Miller has sought federal intervention regarding alleged threats and harassment. Last year, the family engaged local and federal authorities after activist Barbara Wien circulated flyers near their Arlington, Virginia, residence featuring Stephen Miller on a Wanted poster alleging crimes against humanity.

Those materials listed the couple’s Arlington address alongside a QR code encouraging citizens to petition for a congressional investigation, ultimately prompting the Millers to relocate into military housing.
Local legal proceedings concerning that flyer distribution concluded earlier this year when Arlington and Falls Church Commonwealth Attorney Parisa Dehghani-Tafti filed court documents stating that evidence gathered via search warrant failed to support criminal prosecution under state statutes prohibiting the use of personal identity or addresses for intimidation or coercion.
Regarding the latest federal case, prosecutors stated that Proia placed multiple calls daily from varying phone numbers and occasionally left recorded voice messages. Investigators noted that the suspect also reached out to Katie Miller’s mother via troubling text messages, including one that addressed her directly, labeled Stephen Miller as evil, and contained profanity.
In an additional message directed at Katie Miller’s father, the sender used the father’s first name while making inflammatory remarks questioning his reaction to his daughter’s marriage.
