Federal prosecutors in Boston on Thursday charged a Massachusetts man with sending a series of threatening letters containing a suspicious powder, including one addressed to U.S. President Donald Trump's eldest son.
The letter addressed to Donald Trump Jr. led to the Republican president's daughter-in-law, Vanessa Trump, being taken to a hospital after opening it on Feb. 12. Two other people also went to the hospital but the white powder in the envelope proved to be harmless.
Prosecutors charged Daniel Frisiello, 24, of Beverly, Massachusetts, with mailing a threat to injure a person as well as false information and hoaxes for sending threatening letters to at least five addresses around the United States, according to court papers.
