A federal judge has temporarily blocked the deportation of Yunseo Chung, a 21-year-old Columbia University student, after she was arrested during a pro-Palestinian protest. Chung, a legal permanent U.S. resident, sued the Federal government, claiming the deportation attempt violates her free speech rights. U.S. District Judge Naomi Buchwald ruled there was no evidence that Chung posed a national security risk. Chung is a former York County valedictorian.
