Secretary of State Marco Rubio on Rumeysa Ozturk, the Turkish student who was detained: “We revoked her visa. It’s an F-1 visa, I believe. We revoked it, and here’s why—I’ve said it everywhere, and I’ll say it again.

“Let me be abundantly clear: If you apply for a student visa to come to the United States and you say you’re coming not just to study, but to participate in movements that vandalize universities, harass students, take over buildings, and cause chaos—we’re not giving you that visa.

“If you lie, get the visa, and then engage in that kind of behavior once you’re here, we’re going to revoke it. And once your visa is revoked, you’re no longer legally in the United States. Like every country, we have the right to remove you. It’s that simple.

“It’s crazy—stupid, even—for any country to let people in who say, ‘I’m going to your universities to riot, take over libraries, and harass people.’ I don’t care what movement you’re with. Why would any country allow that? We gave you a visa to study and earn a degree—not to become a social activist tearing up our campuses. If you use your visa to do that, we’ll take it away.

“And I encourage every country to do the same. Every country has the right to decide who enters as a visitor. If you invite me to your house for dinner and I start putting mud on your couch and spray-painting your kitchen, you’re going to kick me out.

“We’ll do the same if you come to the U.S. and cause a ruckus. We don’t want that here. Go do it in your own country—but not in ours.”
