This weekend, a former student at Columbia University in New York was arrested by immigration

authorities despite having a green card.

Mahmoud Khalil, who helped organize on-campus protests against Israel's attacks on Gaza as part

of its war with Hamas, was seized, according to President Trump, for allegedly espousing

pro-KHamas views.

William Brangham has our report.

Amna, this arrest is part of the Trump administration's crackdown on anti-Semitism,

particularly on college campuses, which were convulsed by protests last year

during the height of the Hamas-Israel war.

But officials have offered no evidence that Mr. Khalil broke any laws while at Columbia.

And today, crowds gathered in New York City to protest his arrest.

For more on this, we are joined again by Abed Ayyub.

He's the national director for the American Arab anti-discrimination community.

Abed, so good to have you back on the program.

We should say that a judge has ordered that Mr. Khalil cannot be deported until further court proceedings play out,

and a hearing about his arrest is scheduled for later this week.

But when you first heard about this seizure by immigration officials, what was your reaction?

Thank you for having me on. Look, the initial reaction was one of concern, deep concern and

disappointment and concern not just only for Mahmoud, but concern for

this country that we are now going down a path where speech and expression is being criminalized

this way.

And this should be alarming for all Americans, not only those that are standing up for Palestine
