Robert De Niro has played mobsters, hitmen, and corrupt politicians on screen. But according to a new opinion piece in American Thinker, the two-time Oscar winner may now be facing his most unlikely antagonist yet: New York City’s own mayor.
The piece, written by J.R. Dunn and published Saturday, argues that the legendary actor is quietly on a collision course with what Dunn calls the “Mamdani junta” — a pointed reference to the city’s current chief executive and his administration’s aggressive push to tax wealthy property owners.
What makes De Niro a potential target? The article notes that while he’s best known for his movie career, the 82-year-old is also something of a real estate mogul. Over the years, De Niro has poured much of his acting earnings into property purchases in Manhattan’s downtown area, including a restaurant, a hotel, and a number of commercial buildings in the TriBeCa neighborhood. One writer years ago went so far as to claim he owned nearly every commercial building in TriBeCa — an assertion Dunn calls unlikely, given the neighborhood’s size, but one that underscores the actor’s deep footprint in the area.
According to the piece, the bulk of De Niro’s net worth — estimated at roughly $500 million — consists of real property. That, Dunn argues, makes him a natural target of Mamdani’s campaign against “bourgeois property owners” who are allegedly exploiting Manhattan’s housing-starved proletariat.

Pied-à-Terre Law: A New Weapon
The specific threat, per the analysis, comes from the city’s newly enacted pied-à-terre law. The measure is aimed at property owners who maintain apartments in New York City while having their primary residence elsewhere. The goal, supporters say, is to free up housing stock in a city facing an acute shortage — but critics view it as a thinly veiled wealth tax targeting the ultra-rich.
Dunn points out that De Niro appears to fit the law’s description “like a glove.” He owns a house in Montauk, has an estate north of the city, and holds another apartment in Los Angeles — meaning his Manhattan properties could plausibly be classified as pied-à-terres rather than primary residences.
The piece acknowledges that it’s unknown whether De Niro’s name appears on any city enforcement list, but argues that’s little comfort. “This is only the first step in Mamdani’s campaign,” Dunn writes, predicting the effort “will only increase in intensity and viciousness as time passes.”
A Growing Controversy
The pied-à-terre tax has been a lightning rod in recent weeks, according to the article. Dunn describes a rally Mamdani held in front of billionaire Ken Griffin’s apartment — an event that implicitly scapegoated Griffin and put him in the sights of “unbalanced members of his movement.” The timing is especially sensitive, coming just two years after the assassination of UnitedHealthcare CEO Brian Thompson, a shooting that sparked a national conversation about rhetoric aimed at wealthy business figures.

The Mamdani administration’s Department of Finance has also released a database listing 960,000 city property owners — individuals the administration reportedly views as subject to action under the pied-à-terre law. Dunn, clearly unimpressed, calls the list a register of those the “junta views as enemies of the people.”
Perhaps most striking, the article notes the apparent contradiction: even as the administration seeks to penalize wealthy property owners, it’s simultaneously begging corporate CEOs — many of whom may well appear on that very list — to help bail out the city financially.
Uncertain Path Forward
Whether De Niro is actually on the enforcement list remains unconfirmed. But the article suggests the actor’s troubles may just be beginning. Dunn offers a sardonic piece of advice: “Maybe he should dump NYC and settle permanently in LA,” before quickly retracting it with an ironic “Ah, forget I brought that up.”
For now, the situation remains a developing political controversy. What’s clear is that De Niro — long seen as a quintessential New York figure, both on screen and in his business ventures — may find himself caught in the crossfire of a policy fight that shows no signs of cooling down.
