Jack Schlossberg, the Kennedy family scion whose father’s side of the family is Jewish, is officially running for Congress in one of the most Jewish districts in the United States. 

He entered the race on Tuesday night after months of speculation and an initial dismissive reaction from the seat’s current occupant, Jerry Nadler.

Schlossberg, the 32-year-old grandson of President John F. Kennedy who has risen to prominence recently as a progressive social media darling, posted an announcement Tuesday night that focused on Donald Trump and the cost of living.

“We deserve better, and we can do better, and it starts with the Democratic Party winning back control of the House of Representatives,” Schlossberg said.

Schlossberg, 32, is running to represent New York’s 12th Congressional District, which covers the Upper West and East Sides and all of Midtown Manhattan, where he said he was “born and raised, where I took the bus to school every single day from one side of the district to the other.”

Raised with Jewish traditions

His mother is the author and former US ambassador to Australia Caroline Kennedy; Schlossberg’s father is Jewish artist Edwin Schlossberg. His paternal grandfather, Alfred Schlossberg, worked in what he told the New York Times was the “shmatte business,” making men’s dress shirts.

The younger Schlossberg was raised with some Jewish traditions at home, such as incorporating Hanukkah traditions into their holiday parties.

“I feel I’m at least 100% half Jewish,” he told Hey Alma last year, as he broke out as a social media star.

Schlossberg was born in 1993 - one year after Nadler was first elected. Nadler, Congress’ most senior Jewish member, announced in September that he would not be running for reelection to make way for the next generation. Nadler’s retirement opened up an already-crowded race to represent a “crown jewel” of New York politics, with a number of others rumored to be exploring their own candidacies.

Other candidates officially running include Alex Bores and Micah Lasher, both members of the state Assembly, as well as 26-year-old non-profit founder Liam Elkind.

Schlossberg has worked as a political correspondent for Vogue and endorsed Kamala Harris at the Democratic National Convention. He has never held public office - a fact that Jerry Nadler himself hammered home in an interview with CNN following his retirement announcement, when Schlossberg was considering running.

“Well, there’s nothing particularly good or bad about a Kennedy holding my seat. But the Kennedy, unlike Schlossberg, should be somebody with a record of public service, a record of public accomplishment, and he doesn’t have one,” Nadler said. “And so, I don’t think he’s going to be a candidate in the end, and he certainly is not going to be a major candidate. There will be major candidates,” Nadler continued, pointing to Lasher as one example. “I’m sure there’ll be other candidates.”

Schlossberg took Nadler’s criticism in stride, writing on Instagram, “Honestly no offense taken whatsoever ! As a New Yorker, a progressive and an American, I have nothing but thanks and respects to offer Rep Nadler.”

Schlossberg endorsed Zohran Mamdani ahead of the Democratic mayoral primary, and said on Instagram that he didn’t “give a f–k” that he would “piss off” former Gov. Andrew Cuomo, his cousin by marriage. In an Instagram post responding to people who ask why he supports Mamdani as a Jew, Schlossberg said, “If you think that Zohran doesn’t like Jews, you’re f–king brainwashed.”

He added, “We cannot have this thing where if you disagree with Israeli policy, you hate Jews. That’s not good and that’s not fighting antisemitism. That’s horses–t and that’s a cop-out.”

In an interview with the New York Times the day after Mamdani’s election, he said he thought Mamdani’s victory, including his wide margin among young voters, was a positive omen for his own campaign.

Schlossberg defended Mamdani against allegations of antisemitism in that interview. “New York needs to be a safe place for Jewish people,” Schlossberg said. “I’m very sensitive to the Jewish community’s concerns, because I feel them, too. It bothers me.”

While a supporter of Mamdani, he disagreed with the mayor-elect’s pledge to arrest Israeli Prime Minister Benjamin Netanyahu if he sets foot in New York, and, unlike Mamdani, chose not to describe the conflict in Gaza as a “genocide.”

“I think it’s painfully clear that Israel’s committing atrocities in Gaza,” Schlossberg said.

In an interview days before Schlossberg entered the race, Democratic strategist Trip Yang said the 12th district race is “wide open.”

“Jerry Nadler is an icon, trailblazer. Nadler is one of the most popular figures in Manhattan history,” Yang said.

“This is one of the most important congressional districts - a lot of wealth, a lot of power in this district. But it’s an open seat,” Yang said. “So you can have a lot of big names enter right now. It is wide open.”
