Columbia’s Katrina Armstrong Resigns Amid Trump’s Attacks

After agreeing to the Trump administration’s sweeping demands and then appearing to backtrack to faculty, Columbia’s interim president stepped down Friday night—a move that federal officials praised, though it may add to the upheaval at the Ivy League institution that’s facing criticism on multiple fronts, from the federal government to faculty to students.

Katrina Armstrong, who has served as the interim president since last August, is returning to her previous post leading the institution’s Irving Medical Center, according to the Friday announcement.

In a brief statement, she said it had been a “singular honor to lead Columbia University in this important and challenging time … But my heart is with science, and my passion is with healing. That is where I can best serve this University and our community moving forward.” Claire Shipman, a former broadcast journalist and a co-chair of Columbia’s Board of Trustees, will take over as acting president while the university begins a nationwide search for a permanent leader.

The leadership shake-up comes after weeks of turmoil at Columbia as the Trump administration has waged war against the Ivy League institution, stripping it of $400 million in federal contracts for what it calls Columbia’s “continued inaction in the face of persistent harassment” against Jewish students on campus. Trump’s antisemitism task force, which was formed by executive order in early February, then demanded the university implement a number of sweeping reforms, including restructuring its disciplinary process under the Office of the President, expanding the authority of its campus security force and placing its Middle East, South Asian and African Studies department into receivership.

The university announced a week ago that it would comply with the demands, to the frustration of critics who argued that the demands may be unlawful and that giving in to them undermines academic freedom and free speech. On CNN, Education Secretary Linda McMahon praised Armstrong, saying she had had productive conversations with the then-interim president and that Columbia was “on the right track” to having its funding restored.

But according to a transcript of a virtual meeting between Armstrong and faculty members obtained by Bari Weiss’s news outlet, The Free Press, Armstrong told faculty members that many of the changes the university had promised the antisemitism task force would not come to pass. She said there would be “no change” to masking and admissions policies, that the MESAAS department wouldn’t be placed into a receivership, and that the disciplinary process would not move under the Office of the President.

Armstrong seemingly denied those claims in a statement Tuesday, writing, “Let there be no confusion: I commit to seeing these changes implemented, with the full support of Columbia’s senior leadership team and the Board of Trustees … Any suggestion that these measures are illusory, or lack my personal support, is unequivocally false.”

Her sudden resignation was met with enthusiasm from the federal antisemitism task force, which appeared to imply in a statement released Friday night that her leadership would have impeded the task force’s ability to move toward a resolution with Columbia.

“The action taken by Columbia’s trustees today, especially in light of this week’s concerning revelation, is an important step toward advancing negotiations as set forth in the pre-conditional understanding reached last Friday between the University and the Task Force to Combat Anti-Semitism,” the statement read.

While many faculty had strongly opposed Columbia’s choice to give in to the Trump administration’s demands, Armstrong appeared to be generally well-liked among the faculty; in a recent Inside Higher Ed article, Michael Thaddeus, vice president of the campus’s American Association of University Professors chapter, said she was one of the most open leaders he had worked with in his time at Columbia.

Shipman, now the acting president, also praised Armstrong’s leadership in that article, calling her an “exceptional leader” who “came in to help us heal and get our campus in order” and who is skilled at working under “crisis conditions.”

But one AAUP leader noted in an email to Inside Higher Ed that, though he was personally surprised that Armstrong stepped down, it will do little to change the AAUP’s ongoing work to oppose Trump’s crusade against higher education.

“Katrina Armstrong’s resignation changes almost nothing,” wrote Marcel Agüeros, Columbia AAUP’s chapter secretary. “For the past two years, we have been advocating for a greater role for faculty in the decision-making processes of the university. That, and defending our university and all universities against unwanted and likely unlawful interference by the federal government, remains our North Star.”

The AAUP chapter at Columbia last week sued the Trump administration in an effort to restore the $400 million in funding. The lawsuit argues that the funding freeze was a “coercive tactic” that’s already caused irreparable damage.

Shipman will be the third leader of Columbia in nine months; Armstrong took over the role when Minouche Shafik, who had led the New York institution for a little over a year, stepped down in August. Shafik resigned after backlash from both pro-Palestinian students and faculty and Republican lawmakers for how she handled pro-Palestinian encampments at Columbia. Shipman testified before Congress with Shafik last April at a hearing about antisemitism at Columbia.

“I assume this role with a clear understanding of the serious challenges before us and a steadfast commitment to act with urgency, integrity, and work with our faculty to advance our mission, implement needed reforms, protect our students, and uphold academic freedom and open inquiry,” Shipman said in a news release. “Columbia’s new permanent president, when that individual is selected, will conduct an appropriate review of the University’s leadership team and structure to ensure we are best positioned for the future.”

In a statement, Rep. Tim Walberg, the Michigan Republican who chairs the House Education and the Workforce Committee, warned, “Ms. Shipman, while we wish you all good success, we will be watching closely.”
