The Justice Department launched an investigation into clashes that erupted around a Turning Point USA event at UC Berkeley, where protests led to arrests and at least one reported injury. DOJ officials signaled federal interest in campus security and alleged extremist involvement, while the university said it would cooperate with federal and local investigations and conduct its own review. The episode adds a federal law‑enforcement dimension to campus controversies over protest management and speaker access, with implications for public‑university security protocols, event permitting and relationships between campus police and federal agencies.
