Federal policy and campus leaders are colliding over antisemitism on college campuses. The Biden-era and Trump-era policy fights have intensified as the administration renews enforcement efforts and many universities confront complaints from students, faculty and donors. Key actors include the Education Department, university trustees, Jewish student groups and campus advocacy organizations. At Columbia, one year after a high‑profile $400 million ultimatum prompted administrative and governance changes, trustees and administrators have implemented a mix of promised reforms while some commitments remain incomplete. The university’s experience is being cited by other institutions facing federal scrutiny and donor pressure. The developments have produced concrete governance actions — new complaint procedures, funding conditions, and trustee oversight — that campus leaders and governing boards are now navigating under heightened political scrutiny. Institutions should expect more federal inquiries and amplified donor and alumni activism tied to campus speech and conduct.
