Katrina Armstrong, Columbia University's interim president, is being replaced by Claire Shipman. The university did not offer an explanation for the change in leadership.

Columbia University’s interim president Katrina Armstrong said she is leaving her position, ending a tumultuous tenure that was marked by confrontation with the Trump administration and outcry from faculty and students over the school’s response.

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.
