(JTA) — It’s official: Brad Lander is running for Congress — and he says he won’t be “doing AIPAC’s bidding” in representing his district if he’s elected.

The line from Lander’s campaign launch video was a dig at Rep. Dan Goldman, who has represented the 10th Congressional District since 2023, that underscores the degree to which Israel is likely to play a role in the battle for the seat.

Lander’s announcement tees up a showdown between a Jewish progressive challenger and an incumbent Jewish centrist. He enters the race with support from Zohran Mamdani, following weeks of speculation over whether he or Alexa Aviles — a member of Mamdani’s Democratic Socialists of America who was also weighing a run against Goldman — would get the mayor-elect’s high-profile endorsement.

“I’m running for Congress because we need leaders who will fight, not fold,” Lander wrote on X. (Lander’s X account was subsequently hacked and made temporarily private.)

Lander, the outgoing city comptroller, has day-one endorsements from major progressive names including Mamdani, Sen. Bernie Sanders and Sen. Elizabeth Warren, as well as the city’s Working Families Party.

Lander shared a video that touted his ability to fight back against Donald Trump, which featured footage of his ICE arrest. The video took on a gentle tone, with Lander referring to himself as “Dad Lander” and quoting the TV personality Mister Rogers. He talked about his roots in the district, which includes central Brooklyn neighborhoods such as Park Slope, where he served as a three-term City Council member.

But the video also previewed how Israel will play a role as Lander, a self-described liberal Zionist who now calls Israel’s war in Gaza a “genocide” and stumped for the anti-Zionist Mamdani, takes aim at Goldman. The incumbent has been endorsed and received funding from the pro-Israel lobby AIPAC; he also refused to endorse Mamdani because of Mamdani’s stances on Israel.

Goldman has become one of the primary targets of progressives looking to replace moderate Democrats with candidates more aligned with their politics in the wake of Mamdani’s victory. Challengers are also emerging against the vocally pro-Israel Rep. Ritchie Torres, with his AIPAC donations being a point of emphasis of his opponents.

Lander did not name Goldman but referred to his AIPAC ties in the video, saying the “challenges we face” can’t be solved by “doing AIPAC’s bidding in a district that knows our safety, our freedom, our thriving is bound up together.” Two photos of Lander holding signs at Gaza war ceasefire rallies appeared on-screen — one in Hebrew, the other in English.

The 10th Congressional District covers Lower Manhattan, as well as parts of western and central Brooklyn, which Lander represented on the City Council. While Lower Manhattan was more split in the mayoral general election, most of the district’s Brooklyn neighborhoods voted overwhelmingly for Mamdani. The district also includes part of Borough Park, a neighborhood with a large Orthodox Jewish population that strongly supported the centrist mayoral candidate, Andrew Cuomo.

In the video, Lander alluded to Goldman’s refusal to endorse Mamdani, saying that if he beats Goldman, “Our mayor can have an ally in Washington instead of an adversary in his own backyard.”

Mamdani told the New York Times on Wednesday that Lander is a “true leader” who has “unwavering principles, deep knowledge and sincere empathy.”

Lander has been Mamdani’s most prominent local Jewish ally since the pair cross-endorsed each other before the Democratic primary.

Critics said Lander’s efforts, including bringing Mamdani to his synagogue and reinforcing his commitment to the safety of Jewish New Yorkers, merely “kosherized” antisemitism at a time when fierce reaction to the war in Gaza led to Jews feeling unsafe and isolated, and anti-Jewish attacks rose.

Following Mamdani’s general election victory, reports emerged that Lander, who’d been angling for a top position in the new administration, was being left out in the cold without a role. Rumors suggested that Lander might have Mamdani’s support if he pivoted to a congressional run against Goldman. But that support was complicated by the presence of Aviles — Mamdani’s fellow DSA member — who was entertaining a run herself.

All that was put to rest Wednesday, when Lander officially entered the race with the support of Mamdani — who went against the DSA’s endorsement of Aviles, to the chagrin of some of the DSA’s rank-and-file — and Aviles released a statement announcing that she would not be running.

“A split field runs too great a risk of allowing him another damaging term,” she wrote about Goldman, who won his first election in 2022 by two points against a crowded field that split votes between progressive candidates.

Before running for office, Goldman, a millionaire and Levi Strauss heir, drew praise from the left when he served as lead majority counsel on the first impeachment inquiry against Donald Trump in 2019. He has co-sponsored progressive legislation like the Medicare for All Act and the Green New Deal for Public Housing Act, as well as a recent bill that would protect immigrants’ right to appear in immigration court.

But progressives have soured on Goldman, who calls himself a “proud Zionist and steadfast supporter of Israel,” and is criticized for receiving funding from AIPAC — a group whose brand has become increasingly toxic in American politics.

Goldman also faced criticism after Donald Trump Jr. tweeted about a friendly interaction between the two in the Bahamas, following Trump’s Israel-Gaza peace deal.

“Thank you Congressman @danielsgoldman for your kind words today when you saw me, about the incredible job my father did delivering historic peace to the Middle East and bringing the hostages home,” the president’s son tweeted. “Safe travels back from the Bahamas.”

Speculation of a potential Lander challenge had been building since September, when a poll by Data for Progress surveyed voters in the 10th congressional district; in a two-man race between Goldman and Lander, the poll found that Lander would win 52-33.

Democratic strategist Trip Yang advised pumping the brakes in a November interview, pointing out that polls taken so far in advance of an election “don’t matter as much” and that incumbents bring an advantage.

In addition to big names like Mamdani, Sanders and Warren, local politicians have begun throwing their support behind Lander including Assemblymember Robert Carroll — who was an early endorser of Goldman in the 2022 election — and State Sen. Andrew Gounardes.
