Connie Chan's pitch to San Francisco progressives rests on one phrase — working families — and a signature promise to ban members of Congress from trading stocks. Last Monday she shared a stage with Rep. Ro Khanna, one of the highest-volume stock traders in the House and, since July, one of her endorsers. Her other marquee backer, Nancy Pelosi, ranks among Congress's busiest traders too.

Chan is the progressive running to replace Pelosi in Congress, and her brand is built on curbing the money-politics nexus — including a vow to bar lawmakers from trading stocks. But the two national Democrats she's leaning on to broaden her coalition, Khanna and Pelosi, are among the most prolific stock traders in the House. That contradiction, on display at an Aug. 17 campaign town hall, is exactly the line of attack Scott Wiener's campaign is now running.

Khanna endorsed Chan back in July; Pelosi did so months ago. What happened last Monday was a campaign appearance — a "Young voters town hall" at the Potrero Hill office of SEIU Local 1021, moderated by California Working Families Party director Jorge Contreras, whose party plans to back Chan (external source, opens in a new tab) through an independent PAC and field operations. The event was meant to solve a real problem: Chan trailed Wiener by 11 points in June's primary and needs the roughly 18 percent of voters who backed progressive Saikat Chakrabarti. Khanna, a Silicon Valley congressman outside Pelosi's establishment orbit, is the campaign's bridge to those anti-establishment tech voters. But the same coalition-building that makes Khanna useful also hands Wiener a clean line of attack — because Chan's two marquee endorsers are exactly the sort of congressional stock traders her platform vows to stop.

Khanna's case for Chan came down to leverage. Whoever wins the San Francisco seat inherits outsized national weight — Pelosi proved that, he argued at the SEIU hall, according to Mission Local's account of the event (external source, opens in a new tab). A member from this district doesn't arrive in Washington as an ordinary freshman, he said; the seat comes with "a huge megaphone," and that is why it needs a strong progressive holding it.

The town hall was billed for "young voters," and the subtext was tactical. Chan is chasing the Chakrabarti bloc — younger, tech-adjacent, anti-establishment voters who may not know her. A political consultant behind a pro-Chan PAC, David Ho, framed Khanna as a credible envoy to that crowd: a lawmaker who wants to regulate tech and AI without torching the industry, while still taxing the wealthy. Mission Local also notes Khanna is weighing a presidential run and has publicly feuded with tech billionaires — including a weekend clash with investor Mark Cuban over California's billionaire tax — a national profile Chan's labor-forward campaign has struggled to match.

The trouble is what travels with Khanna. Chan has vowed to support federal legislation barring lawmakers and their spouses from trading and holding stocks, and brands herself the working-families candidate against a Wiener she calls a captive of big business. Yet the San Francisco Standard reported (external source, opens in a new tab) that a New York Times review of members' portfolios put Khanna's family trades between $24 million and $147 million — around 7,200 transactions. Pelosi, Chan's other headline endorser, has reported $18 million to $84 million in trades. Both rank among the busiest traders in Congress.

Wiener's campaign pounced on the appearance. His spokesperson, Joe Arellano, said in a statement that Chan was headlining "a Working Families Party event with the most prolific stock trader in Congress," referring to the Times figures, and jabbed: "Working families don't trade stock thousands of times."

Chan's camp refused the frame. Standing beside Khanna, she flipped the question back on her opponent, asking what about Wiener's "billionaire donors?" Her spokesperson, Ian Krager, told the Standard that Chan holds no stocks, supports a trading ban, and has turned down corporate PAC money.

Khanna dismissed the attack as recycled right-wing talking points and pointed to his co-sponsorship of a bill that would force lawmakers' holdings into blind trusts; he has said his family's wealth is handled by outside advisors. He and Pelosi have both publicly backed trading restrictions even as their own portfolios drew fire.

The exchange is a preview of the general election's central argument. Wiener is running on housing and the cost of living, and his allies are working to cast Chan as a progressive in name only. The endorsements meant to broaden Chan's coalition also widen the target on it. Whether Khanna's megaphone reaches Chakrabarti's voters faster than Wiener can turn it into a liability is, for now, the race.
