The Trump administration is relying on an obscure provision of immigration law to justify deporting Mahmoud Khalil, a legal permanent resident, setting up a high-stakes legal battle between the first amendment and what the government claims are its foreign policy powers.
Khalil, a Columbia University graduate who became a leader of pro-Palestinian protests on the campus, was arrested on 8 March by immigration agents. After his arrest, immigration officials said they were seeking to deport him under a provision of federal law that gives the US secretary of state, currently Marco Rubio, the power to deport someone if their presence in the country is deemed to “have potentially serious adverse foreign policy consequences for the United States”.
