Proud Boy who allegedly vowed to 'kill them all' at MAGA riot set to plead guilty: report

On Thursday NBC4 Washington's Scott MacFarlane, the key correspondent covering the January 6 Capitol insurrection trials, reported that Matthew Greene, a Proud Boy from New York City, is set to plead guilty to his role in the attack.

Greene, a high-profile defendant, was accused of "conspiracy involving terrorism," as well as illegal gun charges after an FBI raid on his home uncovered his stockpile. He allegedly shared guerrilla tactics with co-conspirators on the encrypted messaging app Telegram and planned for killing any politicians they could capture, and witnesses of the attack at the Capitol described hearing him proclaim "we'll kill them all."
