Khalil's arrest sparks debate on deportation laws

Mahmoud Khalil, a legal permanent resident and pro-Palestinian activist, was arrested by federal immigration agents at Columbia University. His arrest raises questions about the deportation of green card holders and implications for free speech on college campuses. The Department of Homeland Security claims Khalil's activities align with Hamas, a designated terrorist organization. His legal team has not been informed of any criminal charges, and a federal judge has temporarily halted his deportation while reviewing the case. Khalil's situation highlights the complexities of immigration law, where green card holders can be deported for non-criminal conduct. Experts warn that his arrest may deter free speech, particularly regarding pro-Palestinian advocacy.
