Retiring Rep. Nydia Velázquez is backing Carl Wilson in the race to replace Erik Bottcher on the City Council, amNewYork has learned — deepening her rift with Mayor Zohran Mamdani as the two powerful progressives continue to line up behind rival candidates in a growing series of proxy fights across the city.

Velázquez’s endorsement gives Wilson another prominent boost in the closely watched special election for Manhattan’s District 3, a West Side seat that includes Chelsea, Hell’s Kitchen and the West Village.

The race has drawn heightened attention since Mamdani endorsed Lindsey Boylan on Friday, setting up a contest between the mayor’s progressive coalition and a more traditional network of Manhattan elected officials and local power brokers backing Wilson.

“I know a true grassroots candidate when I see one, and Carl Wilson is exactly that kind of leader. Carl has spent years on the ground doing the work, building trust block by block, and earning the broad local support that only comes from showing up for your community again and again,” Velázquez said in a statement.

“Communities deserve representatives who have put in the work long before Election Day, not just during campaign season. We also need more working people and gig workers in government who understand the realities New Yorkers face every day,” she added.

Wilson, Bottcher’s former chief of staff, has cast himself as a neighborhood candidate focused on affordability, transit, quality-of-life issues and preserving LGBTQ representation in a district that includes the Stonewall Inn and has been represented by out lawmakers for decades. His supporters already include Bottcher, Manhattan Borough President Brad Hoylman-Sigal, Comptroller Mark Levine, current and former Council Speakers Julie Menin, Christine Quinn, and Corey Johnson, and other local Democratic figures.

“I’m incredibly proud to have the endorsement of La Luchadora” — Velázquez’s longtime nickname, Spanish for “The Fighter” — Wilson said.

“Congresswoman Velázquez is a fearless progressive leader who has never backed down from fighting for working people. Her endorsement is a call to action in the final week of our campaign,” Wilson added. “Together, we’re building a movement to deliver bold, transformative change from truly affordable housing and stronger tenant protections to good union jobs and a city that works for everyone. I’m honored to stand with her as we fight for the future our communities deserve.”

Boylan first came to public prominence in 2021, when she accused then-Gov. Andrew Cuomo of sexual harassment, which he denied. In the District 3 race, she has campaigned on universal child care, affordable housing, tenant protections and expanded funding for gender-affirming care, while drawing support from the Working Families Party and a roster of progressive elected officials

The dueling endorsements also add another layer to the increasingly visible tension between Velázquez and Mamdani. When Velázquez announced in November 2025 that she would retire after 33 years in Congress, she pointed to Mamdani’s mayoral victory as evidence that New Yorkers were “hungry for change” and said she had confidence in a new generation of leaders. At the time, she declined to name a successor in NY-7, saying she would consider an endorsement closer to the June primary.

But the relationship appears to have soured as the succession fight took shape. According to The New York Times, after privately discussing possible successors with Mamdani, Velázquez was caught off guard when he moved to back Queens Assembly Member Claire Valdez and warned the decision could fracture the left. Velázquez, days later, threw her support behind Brooklyn Borough President Antonio Reynoso, a longtime ally.

Since becoming mayor, Mamdani has also moved quickly to build a broader endorsement operation. He backed Diana Moreno, his successor in the Assembly, in the special election to replace him, a race she went on to win. Velázquez, meanwhile, had endorsed Rana Abdelhamid in that same contest.

Earlier this year, Velázquez also broke with Mamdani and his allies in another race, backing Brian Romero in a Queens Assembly primary where Mamdani is reportedly aligned with Romero’s opponent, Aber Kawas. 

Mamdani’s endorsement of Boylan jolted the District 3 race just as early voting began, transforming what had been a local special election into a broader test of the mayor’s influence in down-ballot contests. Boylan has lined up support from left-leaning elected officials and groups, including the Working Families Party, while Wilson has assembled backing from labor groups, neighborhood leaders and much of Manhattan’s Democratic establishment.

Boylan joined the Democratic Socialists of America last year, but unlike Claire Valdez, Diana Moreno and Aber Kawas, she was not endorsed its NYC chapter. 

Political observers previously told amNewYork the race had looked like Wilson’s to lose before Mamdani stepped in, but the mayor’s involvement has tightened the contest and raised the stakes.

The fight has also reopened a debate over the meaning of District 3’s political identity. Wilson and many of his backers have argued the district should continue sending an LGBTQ representative to the Council, pointing to its long history as a queer political stronghold and the symbolic weight of a seat anchored by Stonewall. But others, including former Councilmember Tom Duane, have argued the district no longer needs to function as a de facto LGBTQ seat now that queer representation has expanded across the city.

Early voting is already underway in the special election, and Election Day is April 28. Other candidates in the field include Leslie Boghosian Murphy and Layla Law-Gisiko.
