Harvard University has implemented a hiring freeze in response to the Trump administration's threat to withhold federal funding due to the school's handling of anti-Semitic protests on campus. The freeze is intended to address financial uncertainties caused by changing federal policies. The administration's anti-Semitism task force has already canceled $400 million in federal grants and contracts to Columbia University for failing to address anti-Semitic incidents. Harvard is also reviewing spending and commitments in order to maintain financial flexibility.
