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.

We need to prepare for a wide range of financial circumstances,” Harvard president Alan Garber and other university leaders said.
