Protesters occupy Trump Tower following arrest of Columbia student

March 13 (Reuters) - Scores of people poured into the lobby of Trump Tower in New York City on Thursday to protest the arrest and detention of Columbia University student Mahmoud Khalil, whom the Trump administration aims to deport over his pro-Palestinian activism.

The arrest of Khalil, who is in immigration custody in Louisiana after his arrest in New York on Saturday, has sparked an outcry by Democratic lawmakers, the United Nations special rapporteur on the Occupied Palestinian territories, and civil liberty advocates, among others.
