The Defense Department moved to terminate and restrict long-standing officer education partnerships, canceling fellowships and barring attendance at select Ivy League and top research universities. Secretary of Defense Pete Hegseth issued memos removing Senior Service College fellowships at 13 institutions and naming alternate partner schools, citing concerns about institutional ideology and national-security alignment. The action affects programs that place mid-career officers and senior officials on campus for advanced study, professional military education and research collaboration. Institutions named in the announcements—Harvard, Yale, Princeton, Carnegie Mellon and others—have served as hubs for defense-academia exchanges on AI, space and policy. Universities and affected units warn the move will disrupt officer pipelines, cut graduate training slots and complicate research partnerships that supply talent and technical expertise to the Pentagon.
