Nearly 11,000 Harvard alumni—including 881 Harvard Business School graduates—filed an amicus brief in support of Harvard College in its appeal against the Trump administration’s treatment of federal research funding, according to the filing details. The case, President and Fellows of Harvard College v. U.S. Department of Health and Human Services, has been framed around billions of dollars in federal research support. The brief underscores broad alumni participation across Harvard schools, with HBS signatories representing about 8% of the full group. The appendix, according to the reporting, lists degree and class year, and the filing is described as the largest-ever alumni amicus turnout in American history, based on the brief’s stated record. For universities watching the case, the development signals sustained pressure on federal agencies and continued alumni mobilization around research funding stability, institutional autonomy, and compliance posture in grant-related disputes.
