A federal case is underway against John Anthony Proia III, a 41-year-old man from Massachusetts, who is charged with cyberstalking Katie Miller, the wife of White House deputy chief of staff Stephen Miller. Prosecutors say the conduct involved repeated unwanted contact, including calls and text messages, over a period of weeks.

Multiple outlets report that Proia is arrested and then indicted, with the charge tied to alleged harassment through digital communications. The reporting describes the matter as a cyberstalking case filed by federal prosecutors, and it places the alleged victim in the context of a prominent political family. Coverage varies mainly in emphasis—some sources foreground the arrest, others focus on the federal indictment and the specific allegations of calls and texts—while the core facts remain consistent across outlets.
