Overview

• Announcing on Truth Social during a U.K. trip, President Trump said he is designating Antifa and urged thorough investigations into alleged funders.
• Legal experts note federal law has no domestic terrorist-organization list, creating uncertainty over what authority could effect such a designation.
• Antifa functions as a decentralized movement without formal leadership, complicating any attempt to define targets or apply terrorism statutes.
• The declaration follows the Sept. 10 killing of conservative activist Charlie Kirk, which the administration blames on the radical left despite no public evidence tying the suspect to Antifa.
• Democrats and civil‑liberties advocates warn the move risks chilling dissent and free speech, while Trump aides signal plans to dismantle networks they deem responsible.
