New York City Comptroller Brad Lander says he is running for Congress in New York's 10th District. 

Lander released a campaign video Wednesday morning, talking about his years of service in New York. He said he's ready to take on the Trump administration during what he calls "a moment of dark oppression."

Lander was elected as comptroller in 2021 after spending 12 years in the City Council, where he co-founded the Council's Progressive Caucus. He and his family live in Brooklyn.    

Rep. Dan Goldman, a fellow Democrat, currently represents District 10, serving parts of Brooklyn and Lower Manhattan.   

Lander and Goldman taking on immigration enforcement

Lander ran for mayor earlier this year and gained national attention when he was arrested while observing immigration court at 26 Federal Plaza. He was released hours later, and the charges were dropped. He has since returned to observe court several times. 

"While the oligarchy drives an affordability crisis, they shouldn't be able to buy a seat in Congress. While our neighbors are being demonized and attacked, we can put our bodies on the line to protect them," Lander said in his campaign video. "New York is for everyone."

The day after Lander's arrest, Goldman and Rep. Jerry Nadler also visited 26 Federal Plaza to observe immigration proceedings and said they were denied access to a U.S. Immigration and Customs Enforcement field office inside the building, where people were being detained. 

Goldman on Tuesday joined Reps. Adriano Espaillat and Nydia Velázquez announcing new legislation to stop federal agents from arresting immigrants as they show up for court-ordered appearances. 

"Dan is focused on stopping the Trump administration from what they're doing to immigrant families in his district right now. He's proud of his progressive record in Congress and will deal with Brad and other challengers in the new year," a spokesperson for Goldman's campaign said after Lander's announcement. 

Lander says he has Mayor-elect Mamdani's endorsement

Lander said he has been endorsed by Mayor-elect Zohran Mamdani, who cross-endorsed with Lander during ranked choice voting in the Democratic primary for mayor. 

He said he also has the support of Sen. Bernie Sanders, Sen. Elizabeth Warren, New York State Sen. Andrew Gounardes, New York State Assemblymember Robert Carroll, New York City Public Advocate Jumaane Williams, and the Working Families Party. 

Sanders released a statement Wednesday calling Lander a "relentless fighter for working people."

"Brad Lander is a public servant who will bring a much-needed voice to Congress. He will deliver for the people of New York and all working class Americans. I am proud to endorse him," Sanders said.
