Former House Speaker Nancy Pelosi (D-CA) is bringing the full weight of her political influence to bear in an increasingly bitter fight over who will succeed her in Congress.
Pelosi, who has represented San Francisco in Congress for nearly four decades, is throwing her support behind San Francisco Supervisor Connie Chan as she works to defeat state Sen. Scott Wiener, and to do it, the retiring congresswoman has spent weeks mobilizing her network on Chan’s behalf. She has hosted major fundraisers for the supervisor, secured endorsements from congressional allies, and even loaned a top adviser to Chan’s campaign.
“Nancy has basically taken over Connie’s campaign,” Wiener told Politico, contrasting Chan’s operation with his own campaign, which he said has “enormous grassroots support.”
Pelosi has made clear that she intends to see Chan elected. “I know and love this district, I know the Congress, and I know Connie. I’m proud to endorse Democrat Connie Chan and ask you to join me in electing her to Congress,” Pelosi said when she endorsed Chan.
Pelosi’s intervention is particularly notable because Wiener was once considered an ally. The two have known each other for decades, and Pelosi previously supported Wiener in his campaigns for local office. But their relationship deteriorated as Wiener positioned himself to succeed Pelosi. Wiener announced his congressional campaign in October 2025, before Pelosi publicly announced that she would not seek another term.
The timing of Wiener’s announcement has remained a point of contention among Pelosi’s allies. Former San Francisco Mayor Willie Brown, a longtime Pelosi ally who now supports Chan, told Politico that Wiener had assured him he would not announce a congressional bid before Pelosi made her own plans public. Wiener disputes that account, calling it “fabrication” and saying he never made such a commitment.
Several of Pelosi’s longtime political allies and constituencies have followed her in backing Chan, including organized labor. Chan is also supported by Sen. Adam Schiff (D-CA), the California Working Families Party and Our Revolution. Wiener, meanwhile, has endorsements from the California and San Francisco Democratic parties, along with several major labor unions and a majority of San Francisco’s moderate-leaning Board of Supervisors.
The latest escalation in the intraparty feud came over an AI-powered campaign chatbot created by Wiener’s campaign to attack Chan. The website, ConnieChan.ai, portrayed Chan as someone who says “no” to proposals involving housing and public transportation. Pelosi and a coalition of Democratic lawmakers and San Francisco political organizations condemned the chatbot, arguing that it could reinforce sexist and racist stereotypes.
“Women have spent generations fighting to have our own voices heard in the halls of power,” Pelosi and her allies said in a joint statement. “We should not have to fight against artificial intelligence putting words in our mouths.” Wiener later apologized and announced that he would remove both the chatbot and the billboards advertising it.
The controversy has nevertheless given Pelosi another opportunity to draw a sharp contrast between her preferred successor and Wiener. Pelosi’s political intervention comes after the June primary demonstrated that her endorsement alone may not be enough to determine the outcome. Wiener finished first with roughly 41% of the vote, while Chan received about 29%, sending the two into the November general election under California’s top-two primary system.
Pelosi has said her support for Chan is motivated in part by concerns over female representation in the Bay Area’s congressional delegation. Several prominent women who once represented the region, including former Sen. Dianne Feinstein, Vice President Kamala Harris, former Rep. Jackie Speier and former Rep. Anna Eshoo, have all been succeeded by men.
With Pelosi deploying her fundraising network, congressional relationships and longtime San Francisco allies on Chan’s behalf, the November contest is shaping up as more than a race between two Democrats. It is also a test of whether one of the most powerful political figures in San Francisco history can determine who inherits the seat and influence she spent nearly 40 years building.
