A Palestinian activist who led student protests at Columbia University is facing deportation after being arrested by federal immigration officials. The Trump administration claims that the arrest of Mahmoud Khalil, a legal permanent resident, is the first of many as they crack down on campus opposition to the war in Gaza. However, a federal judge has temporarily blocked Khalil's expulsion from the country. Khalil's lawyers argue that he has a right to due process as a legal permanent resident and that the government is targeting and chilling his free speech. They have also petitioned the court to have him returned to New York, as his wife is eight months pregnant.
