William Ernst Oberndorf (commonly known as Bill Oberndorf) is a San Francisco-based billionaire hedge fund manager and a significant donor to Republican and centrist Democratic causes. While much of his public profile focuses on education reform and California-specific political recalls, he is documented as a member of a network of donors that supports pro-Israel advocacy and candidates aligned with the Israel lobby.
1. Direct Philanthropic Support for Pro-Israel Organizations
Through the Oberndorf Family Foundation, Oberndorf has provided financial support to organizations specifically focused on Israel and its relationship with the United States.
- American-Israel Democracy Coalition (Brothers & Sisters for Israel): In 2024, the Oberndorf Family Foundation issued a grant of $5,000 to the American-Israel Democracy Coalition, an organization affiliated with the Israeli group Achiot VeAchim L’Israel (Brothers and Sisters in Arms), which pivoted from domestic protests to high-profile advocacy and humanitarian efforts following the October 7 attacks.

2. Association with the Pro-Israel Donor Network
Political reporting and industry trackers have identified Oberndorf as part of a specific cohort of “pro-Israel megadonors” whose contributions are frequently funneled toward candidates who support unconditional U.S. military aid to Israel.
- Funding Pro-Israel Candidates: Oberndorf is cited alongside prominent pro-Israel donors such as Haim Saban and Paul Singer as a key financial backer of Senator Cory Booker. Booker is noted for his vocal support of Israeli military policy and his receipt of millions in support from groups like the American Israel Public Affairs Committee (AIPAC) and Democratic Majority for Israel (DMFI).
- Presence in Lobbying Circles: Oberndorf and his wife, Susan Oberndorf, are frequently documented in reports tracking the activities of the pro-Israel lobby. They have been listed as attendees or affiliates of major pro-Israel events, including those hosted by AIPAC.
3. Contextual Political Alignment
Oberndorf’s political expenditures often align with organizations that prioritize a strong U.S.-Israel relationship as a core tenet of their foreign policy platform.
- Conservative Leadership Fund Support: Oberndorf has donated millions to the Republican Senate Leadership Fund and other PACs that consistently advocate for a “pro-Israel” hawkish foreign policy, including opposition to the Iran Nuclear Deal—a primary objective of the Israel lobby.
