The order accuses Antifa of organizing political violence — including riots, attacks on law enforcement and doxing — with the goal of overthrowing the US government. Trump similarly vowed to designate Antifa a terrorist organization in his first term, and legal analysts said the move would likely face constitutional challenges. The president announced last week he would designate Antifa as a terrorist organization, part of his planned targeting of left-wing groups following the assassination of conservative activist Charlie Kirk. “I am pleased to inform our many U.S.A. Patriots that I am designating ANTIFA, A SICK, DANGEROUS, RADICAL LEFT DISASTER, AS A MAJOR TERRORIST ORGANIZATION,” Trump posted on social media last week.
