Mamdani and Trump have been critical of each other, with Trump having backed Mamdani’s opponent, Andrew Cuomo.

Mamdani, for his part, has been critical of the Trump administration’s policies, including its crackdown on immigration and US support for Israel during the Gaza war.

“We have agreed that this meeting will take place at the Oval Office on Friday, November 21st,” Trump said on social media on Wednesday.

Mamdani told reporters earlier this week that his team had reached out to the White House to arrange a meeting.

A Mamdani spokesperson said on Wednesday the mayor-elect planned to meet Trump in Washington “to discuss public safety, economic security and the affordability agenda.”

During the mayoral election campaign, Trump threatened to withhold billions of dollars in federal funding from the city if Mamdani won.

The US federal government is providing $7.4 billion to New York City in fiscal year 2026, or about 6.4% of the city’s total spending, according to a New York State Comptroller report.

Since Mamdani’s rise, Trump has incorrectly labelled him as a “communist.”

Mamdani made countering the 79-year-old president’s actions in the city, especially on immigration, a centrepiece of his successful campaign.

Mamdani will be sworn in as mayor on January 1.
