The Trump administration has not been subtle about its intentions. A White House official, speaking anonymously to the Free Press, told the right-leaning media organization that Khalil’s arrest would be a “blueprint” for other actions.

Rubio’s letter notified DHS that he had revoked both targets’ visas, setting in motion plans for U.S. Immigration and Customs Enforcement to arrest and attempt to deport them, according to a senior DHS official and another U.S. official who spoke on condition of anonymity to describe how the operation against Khalil took shape.

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

I was a student at Columbia University, where I covered tense campus protests over the Israel-Hamas war for the college newspaper and for POLITICO. So I’m familiar with Mahmoud Khalil, a former Columbia student who I’ve chatted with in the past and appears to be the first target of the Trump administration’s effort to crack down on student protesters.

Noor Abdalla, wife of detained Palestinian Columbia University student Mahmoud Khalil, says she thought her husband didn't have to worry about ICE.

Lawyers said the Palestinian student activist was handcuffed, shackled and flown to Louisiana by agents he said never identified themselves.
