Judge halts Mahmoud Khalil's deportation over free speech

Mahmoud Khalil, a Columbia University graduate student and green card holder, was detained by immigration officials after participating in anti-Israel protests. The government claims he poses a threat to U.S. national security, but critics argue this violates his First Amendment rights. A judge has temporarily halted Khalil's deportation, requiring the government to justify its actions. Khalil, of Palestinian descent, is not accused of breaking any laws, raising concerns about the basis for his detention. The government's vague allegations include mobilizing support for Hamas and spreading antisemitism, but no evidence has been presented. Critics warn this could set a dangerous precedent for targeting activists based on their political beliefs.
