Columbia’s interim President Katrina Armstrong announced she will ban masks on campus, with exemptions for health or religious reasons, train three-dozen campus police officers with authority to arrest people, and appoint a new senior vice provost who will conduct a “thorough review” of the Middle East studies department.

The moves came amid unprecedented pressure on the Ivy League university from the White House. Earlier this month, the federal education department moved to terminate $400 million in federal funding for Columbia, citing what it called “relentless violence, intimidation and antisemitic harassment” on campus.

Federal education officials then sent Columbia a detailed list of demands for the funding to be restored.
