Education Secretary Linda McMahon posted a harshly worded letter to Harvard on Monday saying the school must meet several criteria to receive new grants.

A letter from Linda McMahon, the education secretary, said university leaders must demonstrate more responsible management before receiving additional federal grants.

Harvard University will receive no new federal grants until it meets a series of demands from President Donald Trump’s administration, the Education Department announced Monday. The action was laid out in a letter to Harvard’s president and amounts to a major escalation of Trump’s battle with the Ivy League school.
