Columbia University's interim President Katrina Armstrong is resigning, days after the university agreed to policy changes demanded by the Trump administration.

Columbia University's interim president Katrina Armstrong has resigned, returning to her post running the New York school's medical center.

The former television journalist and co-chair of the university’s board of trustees takes the helm at a time of significant peril for the institution.

Protests against Columbia University are breaking out after the school agreed to the Trump administration's demands to change its policies to restore federal funding. NBC News' Maya Eaglin reports on reactions from students and alumni from the School of International and Public Affairs.

The interim president of Columbia University is stepping down, the school announced Friday, a week after announcing sweeping policy changes – seemingly bowing to the Trump administration’s demands conditioned on federal funding.

Columbia University has appointed Claire Shipman, a co-chair of its board of trustees, as acting president of the institution targeted by the Trump administration with major federal funding cuts. Why it matters: President Trump's administration pulled some $400 million in federal grants and contracts from the school over allegations of antisemitism during pro-Palestinian protests on the campus.

Among the new changes, Columbia agreed to review its admissions policies, ban protesters from wearing masks, bar demonstrations from academic buildings and to put its Middle East studies department under the supervision of a new senior provost with a mandate to review its leadership and curriculum.

The resignation comes after Columbia caved in to demands from Trump, who claims the school failed to fight antisemitism.

The interim president of Columbia University is stepping down, the college announced Friday—one week after the institution agreed to a list of changes demanded by the Trump administration, which had canceled $400 million in federal funding.
