Brad Lander, who has served as New York City Comptroller since 2022, announced on December 10, 2025, his candidacy for the U.S. House of Representatives to represent New York's 10th Congressional District, setting up a Democratic primary challenge against incumbent Congressman Dan Goldman.

Lander positions himself as a progressive candidate capable of effectively opposing the agenda of former President Donald Trump in Congress. His campaign launch video highlighted the need for more effective solutions to current challenges, criticizing traditional political strategies and the influence of pro-Israel lobbying group AIPAC. He stated, "Our mayor can have an ally in Washington instead of an adversary in his own backyard," and called for collective action against systemic issues such as the affordability crisis and the treatment of marginalized communities.

The primary race is expected to showcase differing perspectives among Democrats regarding the ongoing conflict in Gaza. Lander, who is Jewish and critical of Israel's military actions, has accused Goldman, also Jewish, of supporting Israel's approach during the conflict, which has resulted in significant Palestinian casualties. Lander has publicly condemned Israeli Prime Minister Benjamin Netanyahu's actions, although he refrains from labeling the situation in Gaza as genocide, a term used by Mayor-elect Zohran Mamdani, who has endorsed Lander.

Lander's campaign has also received endorsements from notable progressive figures, including Vermont Senator Bernie Sanders and Massachusetts Senator Elizabeth Warren. His previous political experience includes a failed bid for New York City mayor earlier in 2025 and a tenure as a member of the New York City Council. During his time as Comptroller, Lander's office reported significant financial achievements, including the recovery of $80 million in FEMA funds from the Trump administration, the creation of 50,000 affordable housing units, and savings of over $2.5 billion for taxpayers through the elimination of fraud and waste in city spending.

In contrast, Goldman, who has held the congressional seat since January 2023, previously served as the lead majority counsel during the first impeachment inquiry against Donald Trump. He has faced criticism for his financial influence in politics, having spent $4 million of his own money during his 2022 campaign. His spokesperson emphasized his commitment to addressing issues affecting immigrant families in his district and highlighted his progressive record in Congress. Lander has criticized Goldman for his perceived inaction against Trump’s policies, particularly on immigration, suggesting that Goldman has relied on ineffective measures such as press conferences and letters. Lander himself was arrested by U.S. Immigration and Customs Enforcement (ICE) while observing immigration proceedings earlier this year.

The primary race is viewed as a potential test of the Democratic Party's alignment with progressive values, particularly in light of the recent humanitarian crisis in Gaza. Lander's campaign seeks to challenge the influence of corporate interests in politics, advocating for a more equitable approach to governance.
