During Columbia University's graduation, acting President Claire Shipman acknowledged the absence of detained student activist Mahmoud Khalil, prompting protests and disruptions from students. Khalil, facing deportation for his pro-Palestinian activism, has been in custody since March. The ceremony saw mixed reactions, with some students chanting for Khalil's release and others protesting against Israel's actions in Gaza. Despite warnings from school officials against disruptions, protests continued, reflecting ongoing tensions at the university regarding foreign student rights and U.S. immigration policies.
