Trump and Mamdani meet in the Oval Office saying they both care about affordability

"We're going to be helping him, to make everybody's dream come true, having a strong and very safe New York," the president told reporters with Mamdani beside him in the Oval Office.

"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.

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.

"I think he is going to surprise some conservative people, actually," said Trump, who later seemed to take little umbrage when reporters asked Mamdani to clarify his past statements indicating that he thought the president was acting like a fascist.

Mamdani, a democratic socialist 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 labeled Mamdani as a "communist" and threatened to yank federal funds from his hometown.

Trump loomed large over the mayoral race this year, and on the eve of the election, 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 said he would 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.

For Mamdani, a sit-down with the president of the United States offered the state lawmaker who until recently was relatively unknown the chance to go head-to-head with the most powerful person in the world.

The meeting gave Trump a high-profile chance to talk about affordability at a time when he's under increasing political pressure to show he's addressing voter concerns about the cost of living.

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

The chance for some Oval Office drama

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 as Trump seemed sympathetic to his policies to want to build more housing.

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