A US judge has blocked the Trump administration's attempt to detain and deport a Columbia University student who was targeted for her involvement in pro-Palestinian demonstrations. The judge issued a temporary restraining order, stating that there was no evidence that the student posed a danger to the community. The government argued that the student undermined US foreign policy, but her legal team argued that immigration laws were being misused to suppress political speech. The Trump administration has made Columbia University a central focus of its crackdown on foreign students and academics.
