"In March, Mahmoud Khalil, a green card holder and a leader of pro-Palestinian demonstrations on the Columbia campus, was arrested and detained by immigration officials for several months. That month, Rumeysa Ozturk, a student visa holder, was arrested by immigration officials and detained for several weeks, apparently because she was an author of an opinion essay criticizing Tufts University for its response to the Israel-Hamas war."

Yeah, let's pretend they were arrested for "speech" and not their illegal activities.
