Feds Charge Man Accused Of Stalking Stephen Miller’s Wife
A Massachusetts man allegedly turned Katie Miller’s phone into a pipeline of harassment — then dragged her parents into the barrage.
Federal authorities arrested John Anthony Proia III, 41, of Waltham, on Thursday after a Boston grand jury indicted him on one count of cyberstalking. Prosecutors allege he targeted the conservative podcaster and wife of White House deputy chief of staff Stephen Miller with weeks of disturbing communications.
Proia pleaded not guilty during his initial appearance in federal court in Boston, according to The Hill’s reporting.
Dozens Of Contacts — And Shifting Phone Numbers
According to the Justice Department, Proia allegedly contacted the victim at least 40 times between Aug. 3 and Sept. 23, using multiple phone numbers.
Some days brought repeated communications. Calls allegedly came late at night, with the caller using a menacing tone and frequent expletives.
Prosecutors say the numbers came from internet calling and messaging applications that allow users to generate new numbers and obscure their identities.
The indictment does not identify Katie Miller by name. However, an administration official familiar with the investigation confirmed her identity to NBC News. The Washington Examiner also reported independently confirming that she was the alleged victim.
The alleged harassment reached beyond Miller’s own phone.
Prosecutors say Proia sent vulgar messages to numbers associated with her parents, attacking their daughter and describing Stephen Miller as a “Jewish Nazi/white supremacist.”
U.S. Attorney Leah Foley said the communications profoundly disrupted the family’s lives and warned that attempts to conceal a caller’s identity would not prevent prosecution.
Miller Thanks Investigators
The FBI’s Joint Terrorism Task Force made the arrest, according to the bureau’s Boston office. Special Agent in Charge Ted Docks said the alleged campaign sought to frighten the victim and her family and caused significant emotional distress.
Attorney General Todd Blanche welcomed the charges Thursday, writing on X that the alleged behavior was “criminal and will be treated as it should — with prosecution!” according to The Hill.
Miller responded with a public thank-you to the officials who handled the case.
“Thank you Todd Blanche, Leah Foley, and the FBI Washington Field Office for keeping me and my family safe,” she wrote in the post quoted by The Hill.
“Good to see a Boston grand jury indict this man.”
