A Massachusetts man was charged Thursday with sending the threatening letter filled with white powder to Donald Trump Jr. that sent his wife to the hospital — along with four other bizarre letters mailed to a California prosecutor, a law professor, a senator and actor Antonio Sabato Jr.

Daniel Frisiello, 24, was arrested after what prosecutors called "a textbook federal investigation" that traced the unsigned letters to him after he also ordered a "glitter bomb" for one of the recipients, using his own name.
