Harvard University is the latest school to implement a hiring freeze as federal funding remains uncertain. President Trump has threatened to cut federal funding for schools that allow "illegal" protests. Universities use millions of dollars in federal funding for student aid and research programs.

The hiring pause at one of the nation’s wealthiest schools comes after other schools have also announced efforts to save money.

Columbia University, the scene of some of the most dramatic protests against Israel, said it was punishing students who occupied a building almost a year ago and will transform its approach to managing demonstrations.
