President Donald Trump threatened New York state lawmaker Zohran Mamdani with arrest if the presumptive Democratic nominee for New York City mayor defies Immigration and Customs Enforcement operations.

The president also continued to allege the 33-year-old Democratic socialist is a “communist” while talking to reporters Tuesday at the new so-called “Alligator Alcatraz” migrant detention center in Florida’s Everglades.

When asked by a reporter what his message is to Mamdani – after he said in a victory speech following the New York City Democratic mayoral primary that he would “stop masked ICE agents from deporting our neighbors” – Trump responded, “Well then, we’ll have to arrest him.”

“Look, we don’t need a communist in this country, but if we have one, I’m going to be watching over him very carefully on behalf of the nation,” Trump continued.

Trump also referenced false claims that Mamdani is in the country illegally.

“A lot of people are saying he’s here illegally,” Trump said. “We’re going to look at everything. Ideally, he’s going to turn out to be much less than a communist. But right now he’s a communist. That’s not a socialist.”
