Story summary
John Anthony Proia III, a 41-year-old resident of Waltham, Massachusetts, was arrested and charged on Thursday for allegedly cyberstalking Katie Miller, wife of White House deputy chief of staff Stephen Miller.

The U.S. Attorney’s Office for the District of Massachusetts characterized these communications as "disturbing." Proia was indicted by a federal grand jury in Boston on one count of cyberstalking.
