Demonstrators plan to take over Federal Plaza in New York City on Monday to demand the release of Mahmoud Khalil, a Palestinian activist and Columbia University graduate arrested by federal immigration agents.

Agents told Mahmoud Khalil’s attorney that they were revoking Khalil’s green card. He is legally considered a permanent resident.
