Domestic Extremism and Political Violence

An anonymous 12‑page letter titled "A Real American Response to Foreign Terrorist Invasions" was delivered to the Sonoma County Republican Party office in Northern California, calling for an 'all‑out war' on U.S. Immigration and Customs Enforcement (ICE) agents and detailing how to build a chemical improvised explosive device. The unsigned document, which references the early‑January ICE killing of Renee Nicole Good in Minneapolis, labels ICE personnel 'domestic terrorists,' urges that agents be 'sent home in a body bag,' and explicitly calls for them and their backers to be 'IED’d, run over with vehicles, shot at by snipers, sprayed with toxic chemicals.' It includes step‑by‑step IED instructions in a section titled "Carrying the War Back to the ICE Invader Murderers and Protecting Our Personnel" and likens the effort to a 'private patriotic' action in the mold of Jan. 6 rioters. The letter also names Trump‑era officials such as DHS Secretary Kristi Noem and aide Stephen Miller, along with ICE critic Rep. Ilhan Omar, as part of a broader screed against the administration’s immigration crackdown. The Sonoma GOP says it is cooperating with authorities; while the article does not spell out an FBI response, such explicit, instructional threats against federal officers are typically treated as serious domestic‑terrorism concerns.
