Sen. Kirsten Gillibrand (D-NY) apologized to Zohran Mamdani for recently saying that he had made “references to global jihad,” as New York Democrats continue to weigh their response to the 33-year-old democratic socialist’s stunning upset in New York City’s mayoral primary last week that sent shockwaves through the party establishment.

The senator, who is among several Democratic leaders who have so far refrained from endorsing Mamdani in the general election, claimed in a radio interview last week that the Democratic nominee had made comments that are alarming to Jewish voters in New York, alluding to his controversial defense of calls to “globalize the intifada,” a phrase critics interpret as provoking violence against Jews.

“They are alarmed by past positions, particularly references to global jihad,” Gillibrand said in the interview on WNYC. “This is a very serious issue because people that glorify the slaughter of Jews create fear in our communities. The global intifada is a statement that means ‘destroy Israel and kill all the Jews.’”

While a spokesperson for Gillibrand, whose comments drew backlash, soon clarified that she “misspoke in that instance,” her team added on Tuesday that the junior senator had also privately apologized to Mamdani on Monday night, according to a readout of their call first shared with Politico.

The senator “apologized for mischaracterizing Mamdani’s record and for her tone on the call,” the readout stated, adding Gillibrand “said she believes Mr. Mamdani is sincere when he says he wants to protect all New Yorkers and combat antisemitism.”

The news of her apology came shortly after Mamdani had formally clinched the Democratic nomination on Tuesday, in a resounding, 12-point victory over former New York Gov. Andrew Cuomo, his chief rival in the Democratic primary, who had already conceded.

Mamdani, who significantly expanded his initial seven-point lead on election night, won 56% of the vote in the third and final round of ranked-choice tabulations, with Cuomo in second place at 44%, according to the New York City Board of Elections results.

“I am humbled by the support of more than 545,000 New Yorkers in last week’s primary,” Mamdani said in a statement. “This is just the beginning of our expanding coalition to make New York City affordable. And we will do it together.”

Mamdani has been seeking to shore up support from Democratic leaders as he prepares for a fall general election against Eric Adams, the incumbent mayor running as an independent; Curtis Sliwa, the Republican nominee; and Jim Walden, an attorney also running as an independent. Cuomo will also be on the November ballot on an independent line, but has not yet indicated if he will mount a campaign.

Even as Mamdani has claimed backing from a growing number of state and local party leaders, federal lawmakers have largely been hesitant to fully embrace him, as he has continued to decline invitations to condemn the phrase “globalize the intifada,” an issue that has dogged his campaign in recent weeks.

Gillibrand, for her part, said in the radio interview last week that she had spoken with Mamdani about Jewish security concerns, and that he had agreed to work with her to “protect all residents” amid rising antisemitism.

“These are things that I think are important to New Yorkers, and I will work with him when he gets elected, if he gets elected, to make sure everyone is protected,” she said.
