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.

With uncertainties around federal funding for higher education, some schools are cutting back. Experts say that could hurt not only students and faculty, but ultimately make the U.S. less competitive.
