Scott Wiener, a California state senator who sponsored state AI safety legislation, won the race for Nancy Pelosi’s open San Francisco congressional seat. He says he wants Congress to establish stronger oversight of AI, but his election does not itself create new rules, and the prospects for federal legislation remain uncertain.

Scott Wiener, a California state senator who authored state legislation on artificial intelligence risks, has won the race for Nancy Pelosi’s open San Francisco seat and says he is prepared to pursue federal AI regulation. His election could give Congress a new member with direct experience writing AI rules, but he has not yet taken office and no federal policy change has resulted from the race.

Wiener spoke to MIT Technology Review on Friday, a few hours after he was declared the winner, and said he was concerned about the pace of AI development. He pointed to a report released the previous day by the nonprofit METR that had been widely interpreted as evidence that Anthropic had achieved recursive self-improvement—a process in which AI contributes meaningfully to its own development. That interpretation is not established here as a confirmed finding that Anthropic achieved recursive self-improvement.

“It’s very concerning,” Wiener said of the report, describing it as evidence, in his view, that the time available for regulation may be shrinking. He said he had hoped Congress would take decisive action before the end of 2026, but added: “That does not appear to be happening.” He also called for slowing AI development, saying, “Because it’s moving very quickly, and we could sleepwalk into a disaster.”

Wiener has already shaped policy debates in California. His 2024 bill, SB 1047, was intended to address risks from advanced AI but was vetoed by Gov. Gavin Newsom. Wiener later sponsored SB 53, a less restrictive measure that Newsom signed. The MIT Technology Review report says both bills have influenced proposed federal legislation; the details and effects of those proposals remain separate from Wiener’s election.

The developmentScott Wiener’s election to Nancy Pelosi’s former seat could bring a lawmaker with a record of AI regulation into Congress, where he says he will push for federal oversight.

A State Lawmaker Enters Federal AI Debate

Wiener’s arrival could add a lawmaker with experience negotiating AI legislation to a Congress still debating how, and whether, to regulate the sector. He told MIT Technology Review that he supports a strong federal regulator, whistleblower protections, testing and auditing requirements, and a “kill switch” requirement. He also said Congress should use its oversight powers to hold AI companies accountable. These are his stated priorities, not enacted federal policy.

His position could also matter in disputes over whether federal rules should override state laws. Wiener opposes broad federal preemption, arguing that states need room to respond when Congress does not act quickly. That stance puts him at odds with proposals that would limit states’ authority. The eventual balance could affect how companies face regulation across the country and how much latitude states retain to set their own requirements.

The report also describes a political challenge: Wiener’s emphasis on catastrophic AI risks may not match the concerns that dominate public debate. Voters’ opposition to data centers can reflect local worries about electricity costs, water use and nearby development, rather than agreement with arguments about AI losing control. Wiener himself said those community impacts are likely the bigger concern for many people.

From California Bills to Congress

Wiener’s record offers a practical basis for his stated priorities. His first major AI bill, SB 1047, drew attention as a proposed measure aimed at advanced AI risks, but Newsom vetoed it in 2024. Wiener then sponsored SB 53, which the governor signed. The source characterizes SB 53 as lighter-touch; it does not provide enough detail to compare the bills’ specific requirements here.

Wiener’s campaign also faced scrutiny over money from Public First Action, a nonprofit that supports AI regulation and receives substantial funding from Anthropic, according to the report. The organization contributed more than $3 million to his campaign. Critics said the funding raised questions about his closeness to the AI industry. Wiener rejected that criticism, saying the group supported him because he had introduced and passed AI regulation despite opposition from major technology companies.

Wiener said he would be interested in serving if Congress creates a select committee on artificial intelligence, an idea Democrats had discussed since September. He also cited a proposal from California Representative Ro Khanna for a federal AI regulator. His election follows a period of growing debate over both advanced AI risks and the local effects of data-center construction, two concerns that do not always translate into the same policy demands.

““We need to slow this down. Because it’s moving very quickly, and we could sleepwalk into a disaster.””

— Scott Wiener, speaking to MIT Technology Review

Congressional Path Remains Unclear

Wiener’s election does not establish that Congress will pass AI rules, create a federal regulator or adopt his preferred requirements. The report does not specify when a select committee might be formed, whether Wiener would serve on it, or which proposals could advance. The status of the federal bills influenced by California legislation is also not detailed.

The source describes the METR report as widely interpreted as evidence of recursive self-improvement, but does not establish that Anthropic has achieved that capability. The degree of agreement among researchers about the report’s meaning is not provided. Wiener’s warnings are his assessment of potential risks, not proof that loss of control is imminent.

His campaign funding remains a point of dispute: the contribution amount and the nonprofit’s reported funding source are stated in the report, while claims about what the spending says about Wiener’s independence are contested. It is also unclear how far his AI safety agenda will resonate with lawmakers and voters focused on immediate costs and local impacts.

Wiener’s First Federal Steps

Wiener’s next formal step is to take office after winning Pelosi’s former seat. Once in Congress, he could seek a role on a proposed AI select committee and work with lawmakers, including Khanna, on federal oversight proposals. The report does not give a date for a committee decision or for a vote on any AI legislation.

Congressional action will depend on whether proposals gain support and how lawmakers address the division between federal standards and state authority. Wiener has also identified the Trump administration as a significant obstacle: President Donald Trump called catastrophic AI-risk concerns a “hoax” in September, according to the report, and Wiener said cooperation with China would be important to limiting the worst risks. Whether the new congressman can turn his state-level record into federal policy remains to be seen.

Did Wiener’s California AI bill become law?

His 2024 bill, SB 1047, was vetoed by Gov. Gavin Newsom. Wiener later sponsored SB 53, a less restrictive bill that Newsom signed.

Does the METR report confirm that Anthropic achieved recursive self-improvement?

No such confirmation is established in the source material. It says the report was widely interpreted as evidence of recursive self-improvement, while Wiener described it as concerning.

When will Congress pass federal AI rules?

No timetable is confirmed. Wiener said he had hoped for decisive action before the end of 2026, but that did not appear likely at the time of his interview.
