President Donald Trump has signed a multitude of executive orders that have universities across the nation in a panic.

Harvard University officials on Monday announced a “temporary” hiring freeze. In a letter to university staff on Harvard’s website, President Alan Garber and other school officials cited ”substantial financial uncertainties driven by rapidly shifting federal policies” facing universities across the nation.

Higher education leaders have been on edge since President Trump took office in January and announced a slew of executive actions impacting research and academic institutions.

At least two Ivy League universities abruptly stopped hiring faculty Monday, partly prompted by fear that federal grant funding will be cut.

"It is meant to preserve our financial flexibility until we better understand how changes in federal policy will take shape and can assess the scale of their impact."

Harvard University announced it will be implementing a temporary hiring freeze due to“rapidly shifting federal policies,” according to a Monday letter from Harvard President Alan Garber.

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

Harvard University says it is freezing hiring for faculty and staff amid financial “uncertainties” driven by the Trump administration.

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.

Three days after the Trump administration pulled $400 million of federal funding from Columbia University, Harvard University announced a hiring freeze, citing “substantial financial uncertainties driven by rapidly shifting federal policies.”
