Overview
- Using data through July 4, CSIS counted five left‑wing attacks and plots in 2025 versus one right‑wing incident, the June murder of Minnesota legislator Melissa Hortman and her husband.
- CSIS notes left‑wing activity remains low in absolute terms, and its dataset shows 13 deaths from left‑wing attacks over the past decade compared with 112 from right‑wing attacks.
- The study’s July 4 cutoff excludes later events, including the Sept. 10 assassination of Charlie Kirk and an attack on an ICE facility in Dallas, which are not in the current tallies.
- Incidents linked to the Israel–Palestine conflict, such as arson at Pennsylvania Gov. Josh Shapiro’s residence and the killing of two Israeli Embassy staff in Washington, were classified as ethnonationalist and excluded from left/right counts.
- The report suggests the right‑wing decline may reflect policy shifts under President Donald Trump, though it stops short of proving causation, and outside experts caution that ideological classification is messy and trends can quickly reverse.
