NEW YORK (AP) — Handcuffed and shackled, Mahmoud Khalil was rushed from New York to Louisiana last weekend in a manner that left the outspoken Columbia University graduate student feeling like he was being kidnapped, his lawyers wrote in an updated lawsuit seeking his immediate release.

Whatever legal rationale the Trump Administration cooks up, deporting protesters for things they say is wildly un-American—and possibly unpopular, too.

Trying to deport Khalil for demonstrating against Israel is an obvious violation of his rights and an attempt to intimidate others, they say.
