'A Call for Constructive Engagement' — AAC&U Coalition Letter Signed by 600+ College and University Presidents, Including Garber and Eisgruber

On 2025-04-22, AAC&U (American Association of Colleges and Universities) published “A Call for Constructive Engagement,” a joint statement developed in collaboration with university and college presidents and other educational leaders following national meetings convened by AAC&U and the American Academy of Arts & Sciences. Both Alan M. Garber (President, Harvard University) and Christopher L. Eisgruber (President, Princeton University) are named individual signers in the statement’s endorsement list, alongside 600+ other college/university presidents and higher-ed leaders (list confirmed by direct fetch of the primary source; not independently counted in full here).

This is the one instance in the record checked for this ticket that satisfies documented coordination rather than mere adjacency: a joint drafting process (convened national meetings), a shared text, and individual named signature by both Garber and Eisgruber on the same document.

Date correction relevant to research framing: this letter is dated April 22, 2025 — this predates, and is outside, the “fall 2025 through winter 2026” window that motivated this entry’s parent research task. No comparably coordinated joint-signature letter naming both Garber and Eisgruber was found dated within the fall-2025/winter-2026 window itself; see cross-reference below for the fuller negative finding.

Verbatim opening line: “As leaders of America’s colleges, universities, and scholarly societies, we speak with one voice against…” (full statement at primary source).
