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.

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.
