President Donald Trump signed an executive order Monday evening designating Antifa, a leftist agitator group that organizes political violence, as a domestic terrorism organization. Antifa is amilitarist, anarchist enterprise that explicitly calls for the overthrow of the United States Government, law enforcement authorities, and our system of law. This organized effort designed to achieve policy objectives by coercion and intimidation is domestic terrorism. Designation as a Domestic Terrorist Organization. Because of the aforementioned pattern of political violence designed to suppress lawful political activity and obstruct the rule of law, I hereby designate Antifa as a "domestic terrorist organization."
