Can Trump designate it as a domestic terrorist organization?
Antifa is a domestic entity and, as such, is not a candidate for inclusion on the State Department’s list of foreign terror organizations. Dozens of groups, including extremist organizations like the Islamic State and al-Qaida, are included on that list. The designation matters in part because it enables the Justice Department to prosecute those who give material support to entities on that list even if that support does not result in violence.
But there is no domestic equivalent to that list in part because of broad First Amendment protections enjoyed by organizations operating within the United States. And despite periodic calls, particularly after mass shootings by white supremacists, to establish a domestic terrorism law, no singular statute now exists.
The executive order did not specify how Trump he would go about designating antifa as a domestic terrorist organization.
Cool, so now I can call myself a terrorist? That sounds pretty badass actually.
