The money moved through a network of independent expenditure committees, not directly from AIPAC to Chan's campaign. Federal law bars campaigns from coordinating with super PACs. Chan's campaign has not publicly commented on the spending.

The disclosure lands in a race that has drawn unusually large outside money across multiple candidates. Chan faces Saikat Chakrabarti, the former chief of staff to Rep. Alexandria Ocasio-Cortez, and state Sen. Scott Wiener, among others, in the March 2026 primary. Chakrabarti's own operation has been linked to roughly $10 million in independent expenditure activity. Wiener has drawn support from technology-sector PACs.

AIPAC has built a national record of spending heavily against candidates who have been critical of U.S. military aid to Israel. Chakrabarti has been an outspoken critic of that policy. The spending pattern is consistent with AIPAC's documented approach in other congressional primaries.

Chan, a District 1 supervisor since 2020, has not made U.S. foreign policy a centerpiece of her congressional platform. Her campaign materials have focused on housing, transit, and public safety in the district, which covers much of San Francisco's western neighborhoods.

Watch for: Federal Election Commission filings due later this month will give a fuller accounting of which super PACs received AIPAC funds and how those dollars moved. The candidate filing deadline for the March 2026 primary is December 2025.
