The administration of U.S. President Donald Trump said on Monday that it was reviewing $9 billion in federal contracts and grants awarded to Harvard University, part of a crackdown on what it says is antisemitism on college campuses.

The Departments of Education, Health and Human Services and the U.S. General Services Administration said in a written statement that $255.6 million in contracts between Harvard, its affiliates and the federal government were being reviewed, along with $8.7 billion in multi-year grant commitments.

The investigation is the latest move by the Trump administration to pressure American universities to change their policies on a number of issues at the heart of culture wars that have beset the U.S. in recent years.
