Zohran Mamdani put 4 million non-citizens on taxpayer benefits into the record himself.
New York City’s mayor announced Monday that he is suing the Trump administration over the new public charge rule. That rule, set to take effect Friday, allows immigration officers to consider whether a green-card applicant is likely to rely on taxpayer-funded benefits. Mamdani assembled a coalition of cities and counties behind the lawsuit, including Chicago, San Francisco, Seattle, Santa Clara County, and King County.
His central argument against the rule is that as many as 4 million people nationwide could leave public health programs as a result, including 1.8 million children. He warned that people could die. He described the rule as a vehicle for cruelty and said, “cruelty is not how we seek to govern.”

Read that number carefully, because according to the original report, Mamdani offered that figure as an indictment while standing at a podium with visual aids. He was not disputing the core premise of the rule. He was confirming it. The administration’s argument is that large-scale immigration into a broad welfare state produces widespread dependency. Mamdani’s response is that dependency exists and must be protected. That is not a rebuttal. It is an admission with a press release attached.
It also helps to understand what the public charge standard actually is, because the word “cruelty” is carrying a heavy load here. This rule is not a Trump-era invention. It has existed in American immigration law since the 1880s, built on a principle that once needed no defense. A nation may decline to import poverty. Every sponsor of a legal immigrant already signs a binding financial affidavit promising to support that person. The rule simply asks whether that promise is likely to hold.
No citizen is losing a benefit under this policy. No one is being deported over it. A foreign national applying for the privilege of permanent U.S. residency is being asked to show they will contribute more than they consume. Most developed countries operate under the same standard.
Mamdani declared that immigrants are New Yorkers, and that reaching any of them means going through all of them. But there is a meaningful legal distinction between a resident and a citizen. Permanent residency and citizenship are not the same thing. Benefit eligibility has traditionally followed from that difference, and that distinction is not a new concept in American law or in the immigration systems of other nations.
The public charge rule does not change who can come to America. It shapes the criteria used to decide who earns permanent status here. Sponsors already promise financial support in writing. The rule asks whether that promise is credible. Mamdani’s own figures suggest the answer, in millions of cases, may be no.
