Oct 19 (Reuters) - A U.S. grand jury has indicted a jailed Pennsylvania man for threatening to kill the chair of the congressional committee investigating the January 2021 assault on the U.S. Capitol, prosecutors said on Wednesday.
Robert Vargo, 25, of Berwick, Pennsylvania, also threatened to kill the committee chair's family and President Joe Biden, prosecutors said.
He was charged with threatening the president of the United States, threat by interstate communications, and influencing a federal official by threat, the U.S. Attorney's office for the Middle District of Pennsylvania said in a statement.
Prosecutors allege Vargo sent a threatening letter and white powder to the congressional office of U.S. Representative Bennie Thompson, chairman of the committee that is investigating the Jan. 6, 2021, attack on the Capitol.
The letter, which referenced the congressional probe and anthrax, also threatened U.S. District Court Judge Robert Mariani, according to prosecutors.
