Mohsen Mahdawi, an organizer of pro-Palestinian demonstrations, is the latest target of the Trump administration’s crackdown on campus activism.

A Palestinian student at Columbia University went into a Vermont immigration office Monday hoping to begin the final step to becoming a US citizen. But instead of having an interview, Mohsen Mahdawi – who’s been in the United States for a decade – was taken away in handcuffs.

Columbia student Mohsen Mahdawi was detained by immigration authorities, despite his lawyer saying he is a lawful permanent resident.
