President Donald Trump's administration has slashed an additional $450 million in federal grants to Harvard University, escalating a confrontation over alleged liberalism and antisemitism at the prestigious institution. Following previous funding freezes, a federal task force criticized Harvard as a "breeding ground for virtue signalling and discrimination," demanding the university undertake significant reforms to regain taxpayer support. In response, Harvard filed a legal challenge to the sanctions, arguing against the administration's demands for leadership overhaul and policy changes. The move comes amid similar pressures on other high-profile universities. (With inputs from agencies.)
