President Donald Trump encountered a man who had boldly declared himself as “Donald Trump’s worst nightmare,” yet the meeting turned out to be quite the opposite.

Previously, Trump had labeled Mamdani a “100% Communist Lunatic” and a “total nut job,” but during their encounter, he expressed admiration for the man who had criticized his administration as “authoritarian.”

“I believe he might surprise some conservative folks,” Trump remarked regarding the democratic socialist while Mamdani stood beside him in the Oval Office.

The meeting presented strategic advantages for both parties. For Mamdani, it was a valuable opportunity to engage directly with the world’s most influential leader, elevating his profile as a state lawmaker who was relatively obscure until now.

For Trump, it served as a prominent platform to address the issue of affordability, a pressing concern for voters, especially as political pressure mounted on him to tackle the cost of living.

Until now, the men have been political foils who galvanized their supporters by taking on each other, and it’s unclear how those backers will react to their genial get-together and complimentary words.

“We’re going to be helping him, to make everybody’s dream come true, having a strong and very safe New York,” the president said.

“What I really appreciate about the president is that the meeting that we had focused not on places of disagreement, which there are many, and also focused on the shared purpose that we have in serving New Yorkers,” Mamdani said.

‘I’ll stick up for you’

Mamdani and Trump said they discussed housing affordability and the cost of groceries and utilities, as Mamdani successfully used frustration over inflation to get elected, just as the president did in the 2024 election.

“Some of his ideas are really the same ideas that I have,” the president said of Mamdani about inflationary issues.

The president brushed aside Mamdani’s criticisms of him over his administration’s deportation raids and claims that Trump was behaving like a despot. Instead, Trump said the responsibility of holding an executive position in the government causes a person to change, saying that had been the case for him.

He seemed at times even protective of Mamdani, jumping in on his behalf at several points. For example, when reporters asked Mamdani to clarify his past statements indicating that he thought the president was acting like a fascist, Trump said, “I’ve been called much worse than a despot.”

When a reporter asked if Mamdani stood by his comments that Trump is a fascist, Trump interjected before the mayor-elect could fully answer the question.

“That’s OK. You can just say yes. OK?” Trump said. “It’s easier. It’s easier than explaining it. I don’t mind.”

Trump stepped in again when a reporter asked Mamdani why he flew to Washington instead of taking transportation that used less fossil fuels.

“I’ll stick up for you,” Trump said.

Mamdani, who takes office in January, said he sought the meeting with Trump to talk about ways to make New York City more affordable. Trump has said he may want to help him out — although he has also falsely labelled Mamdani as a “communist” and threatened to yank federal funds from the city.

But Trump on Friday didn’t sling that at the mayor. He acknowledged that he had said he had been prepared to cut off funding or make it harder for New York City to access federal resources if the two had failed to “get along,” only to pull back from those threats during the meeting.

“We don’t want that to happen,” Trump said. “I don’t think that’s going to happen.”

Afterward, Mamdani’s former campaign manager and incoming chief of staff Elle Bisgaard-Church told NY1 that the pair clearly clearly disagreed on some issues but were able to find common ground on things like reducing crime.

“We discussed that we share a mutual goal of having a safe city where everyone can move around in comfort and ease,” she said, before later adding, “We know that there have been labels thrown all around that are just simply not fair and we kept it, again, at where we could find agreement on making the city affordable.”

Trump loomed large over the mayoral race this year, and on the eve of the election, he endorsed independent candidate and former Democratic Gov. Andrew Cuomo, predicting the city has “ZERO chance of success, or even survival” if Mamdani won. He also questioned the citizenship of Mamdani, who was born in Uganda and became a naturalized American citizen after graduating from college, and said he’d have him arrested if he followed through on threats not to cooperate with immigration agents in the city.

Mamdani beat back a challenge from Cuomo, painting him as a “puppet” for the president, and promised to be “a mayor who can stand up to Donald Trump and actually deliver.” He declared during one primary debate, “I am Donald Trump’s worst nightmare, as a progressive Muslim immigrant who actually fights for the things that I believe in.”

The president, who has long used political opponents to fire up his backers, predicted Mamdani “will prove to be one of the best things to ever happen to our great Republican Party.” As Mamdani upended the Democratic establishment by defeating Cuomo and his far-left progressive policies provoked infighting, Trump repeatedly has cast Mamdani as the face of Democratic Party.

Some had expected fireworks in the Oval Office meeting

The president has had some dramatic public Oval Office faceoffs this year, including an infamously heated exchange with Ukrainian President Volodymyr Zelenskyy in March. In May, Trump dimmed the lights while meeting with South African President Cyril Ramaphosa and played a four-minute video making widely rejected claims that South Africa is violently persecuting the country’s white Afrikaner minority farmers.

A senior Trump administration official who spoke on condition of anonymity to describe internal discussions said Trump had not put a lot of thought into planning the meeting with the incoming mayor — but said Trump’s threats to block federal dollars from flowing to New York remained on the table.

Mamdani said Thursday that he was not concerned about the president potentially trying to use the meeting to publicly embarrass him and said he saw it as a chance to make his case, even while acknowledging “many disagreements with the president.”

Instead, both men avoided a public confrontation in a remarkably calm and cordial series of comments in front of news reporters.

Mamdani, who lives in Queens — where Trump was raised — has shown a cutthroat streak just as Trump has as a candidate. During his campaign, he appeared to borrow from Trump’s playbook when he noted during a televised debate with Cuomo that one of the women who had accused the former governor of sexual harassment was in the audience. Cuomo has denied wrongdoing.

But the tensions were subdued Friday as Trump seemed sympathetic to Mamdani’s policies to want to build more housing.

“People would be shocked, but I want to see the same thing,” the president said.
