A resurfaced video of President Donald Trump is lighting up the internet — and sending an unmistakable message to New York City’s far-left mayor-elect Zohran Mamdani: If you obstruct federal law enforcement, you will face consequences.

The clip, taken during a summer 2025 press event, has regained relevance after Mamdani — a self-described socialist and one of the most radical politicians elected in New York in decades — vowed repeatedly to block Immigration and Customs Enforcement (ICE) from arresting illegal immigrants in the city. Reporters asked President Trump what he would do if the incoming mayor made good on his promise.

Trump didn’t hesitate.
He didn’t dance around it.
He didn’t give a politician’s answer.

Instead, with the confidence of a leader who actually believes in enforcing America’s laws, Trump replied: **“Then we’ll arrest him.”**

The exchange began when a reporter warned the president that his “beloved New York City” was about to be led by “a communist,” referencing Mamdani’s fiery pro-sanctuary rhetoric and his declaration that ICE would not be allowed to detain criminal illegal aliens under his watch.

Trump, wearing his iconic red MAGA hat, delivered a calm but decisive response: “Then we’ll have to arrest him.”

That message aligns with the stance of former acting ICE Director Tom Homan and other Trump administration officials, who have made it abundantly clear that obstructing federal law enforcement is not “activism” — it’s a crime. And no amount of socialist sloganeering from a mayor-elect changes that.

Mamdani, for his part, has been completely open about his intentions to sabotage ICE operations. During his campaign — one fueled by far-left donors, activist groups, and anti-law-enforcement organizations — he repeatedly promised that the NYPD would **never** assist federal immigration authorities while he is in charge.

He doubled down after the election, telling PIX11 News:

> “We can never go back to the days where Eric Adams would go on national television and open the door to the NYPD handling civil immigration enforcement… What we will ensure is that the NYPD will be delivering public safety, not assisting ICE.”

“Public safety,” in Mamdani’s world, apparently means shielding illegal immigrants — including violent offenders — from deportation while ICE agents are trying to do their jobs. It means ignoring federal law in a city already drowning in crime, chaos, and an unprecedented migrant crisis.

Mamdani even entertained the idea of arresting ICE agents who “break the law” while performing their federally authorized duties — a stunning escalation that borders on nullification of federal authority.

Meanwhile, Trump has made his stance unmistakably clear:
If a mayor attempts to interfere with federal immigration enforcement, that mayor is the one breaking the law — and will be treated accordingly.

As the Biden-era sanctuary city disaster gives way to Trump’s renewed push for law and order, Mamdani’s defiant posture sets up a collision course between a radical city hall and a federal government determined to restore the rule of law.

One thing is certain:
Trump isn’t bluffing — and Mamdani may soon learn what happens when a local socialist tries to take on a federal immigration force backed by a president who actually means what he says.
