Columbia University has issued a range of disciplinary actions, including expulsions and suspensions, against students involved in anti-Israel protests and a library takeover in May. The university has faced mounting pressure from government officials to address campus antisemitism following a series of high-profile demonstrations and incidents since late 2023. Recent actions include reforms to the university's disciplinary policy and new measures aimed at combating antisemitism, which have been welcomed by some members of the Jewish community. The situation remains under scrutiny by lawmakers, with ongoing investigations and calls for further legislative action.
