The Trump administration has recently escalated its destructive and illegal attacks on the core freedoms of American colleges and universities, which we have called on it to halt (Fortune, April 8). The demands issued to Harvard University (in an April 11 letter), followed by the freezing of $2.2 bi llion of federal research funds along with threats to Harvard's tax-exempt status, violate no less than the freedom of all colleges and universities to admit students, hire faculty, and govern themselves consistently with the law, the First Amendment, Title VI of the Civil Rights Act, and long-standing principles of academic freedom. As current and former presidents of academic institutions, we strongly support Harvard’s President Alan Garber, who has rejected the demands on these grounds while the Trump administration threatens to demand control of numerous other schools. Just over three miles from Harvard Square is the Boston Tea Party site where, in 1773, American patriots fought government tyranny. When the Trump administration conditions federal grants and contracts to universities on these demands, it threatens all Americans. Higher education is the greatest source of U.S. global competitiveness, cultural enrichment, and learning.  By partnering with the federal government for decades, American universities have made lifesaving discoveries and increased the prosperity, safety, security, and creativity of our country. When the Trump administration insists on anyone’s compliance with likely illegal and unconstitutional conditions, it is threatening everyone’s freedom from arbitrary rule. When it insists on controlling the admission of students, faculty hiring, and governance of a university, it is also threatening a prime source of the opportunity and economic prosperity of all Americans. We all know from Martin Neimoller’s haunting lament, this authoritarian incursion does not end with Harvard.  Authors: Edward Ayers, University of Richmond (Virginia)  Lawrence Bacow, Tufts University (Massachusetts), Harvard University (Massachusetts)  Kimberly Benston, Haverford College (Pennsylvania) Katherine Bergeron, Connecticut College (Connecticut)  Henry Bienen, Northwestern University (Illinois) Lee Bollinger, Columbia University (New York), University of Michigan (Michigan) Phil Boroughs, SJ, College of the Holy Cross (Massachusetts)  William Brody, Salk Institute, The Johns Hopkins University (Maryland) Robert Brown, Boston University (Massachusetts) Alison Byerly, Carleton College (Minnesota) Albert Carnesale, University of California – Los Angeles (California)  Carol T.
