The Trump administration opened an investigation into anti-Semitism at California State Polytechnic University, Humboldt, after anti-Israel activists allegedly pelted their Jewish classmates with fake blood, and administrators encouraged the students to "hide their Jewish identity to avoid being targeted."

The U.S. Department of Education’s Office for Civil Rights (OCR) launched the investigation in response to a civil rights complaint from the Louis D. Brandeis Center for Human Rights Under the Law, the legal advocacy group said on Tuesday.

Jewish students at Cal Poly have accused administrators of ignoring anti-Jewish attacks and allowing an atmosphere of anti-Semitism to spread on campus, the Washington Free Beacon reported in March.

According to the Brandeis Center complaint, pro-Hamas protesters disrupted a vigil for victims of the Oct. 7 Hamas attacks by drawing a "Zio Corner" chalk circle around attendees and throwing red paint at Jewish students meant to represent the "blood of martyrs."
