More than a dozen schools, including Harvard, MIT, Brown, and the University of Pennsylvania, have frozen hiring.

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.

Harvard University will temporarily freeze hiring as the risk of federal funding cuts by the Trump administration threatens the finances of some of the most prestigious American colleges.
