This week, President Donald Trump has spent a lot of time issuing angry threats against Zoran Mamdani, who recently pulled off a shocking underdog victory in New York City's Democratic mayoral primary.

Trump has been attacking Mamdani as a communist and questioning his U.S. citizenship,

which hints had a coming effort to try to strip that citizenship from him.

What really caught our eye, though, is Mamdani's response to Trump.

It was very sharply worded and quickly laid out the real stakes of this battle.

This is something we think Democrats can learn from,

because it's becoming clear that Trump's threats to denaturalize political opponents

may be on the way to becoming a real thing.

So can Trump denaturalize Mamdani and other political opponents?

What would that look like and what should liberals and Democrats be preparing for right now?

Today we're trying to figure all this out with one of our favorite immigration analysts,

David Beer of the Cato Institute.

Good to finally have you on, David.

Thanks for having me on. It's great to finally

make it here. So let's start with Trump's deranged threats. This week, Trump was asked about

Mamdani's claims that he will resist ICE arrests in New York City. Trump responded by saying,

well, we're going to have to arrest him. Listen to this. 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.

A lot of people are saying he's here illegally.

You know, we're going to look at everything.
