When attorneys for Mahmoud Khalil enter the Thurgood Marshall United States Courthouse in New York on Wednesday, they will have one mission in mind: to get their client, a Palestinian activist, released from an ICE facility in Louisiana and back to New York to be closer to legal counsel and family.

Dozens of University of Chicago students and faculty members rallied on Tuesday in support of a former Columbia University student and pro-Palestinian activist Mahmoud Khalil, who was arrested by federal immigration authorities over the weekend in New York.

Some organizations applauded the move. But the raid chilled other American Jews, even some who consider themselves supporters of Israel.
