Senator Sanders Urges Pause on AI Development, Calls for Congressional Hearings
In a letter sent Monday to the CEOs of OpenAI, Anthropic and Meta, Senator Bernie Sanders of Vermont warned that the United States has crossed a safety threshold in artificial‑intelligence development and urged the industry to halt or delay new model releases. "It is not too late to avoid disaster," he wrote, adding, "Stop building machines that humans cannot control." The letter was accompanied by a separate communication from a group of House Democrats asking Speaker Mike Johnson to schedule hearings with the CEOs of the largest AI companies.
Sanders’ message signals a shift among progressive lawmakers from focusing on the environmental footprint of AI data‑center construction to confronting the technology’s potential societal harms. Voters have raised concerns that AI could raise electricity bills, eliminate jobs and erode retirement savings if the industry falters. While the House Democrats’ letter targets the CEOs, Sanders’ letter points to a need for regulation of the technology itself.
The senator has long championed public ownership of key industries. In June 2026 he introduced legislation to create an AI sovereign‑wealth fund, which would give the federal government a 50 % stake in the country’s largest AI companies through a one‑time tax on their stock. The bill also proposes a freeze on new AI data‑center construction, a measure that has drawn criticism from the Trump administration, which has championed a pro‑AI expansion stance.
All the companies addressed in Sanders’ letter have publicly acknowledged safety concerns. OpenAI releases only models that receive a medium‑risk rating or lower in its internal tests. Anthropic, founded by former OpenAI employees, built its business around safety research and has released a series of models, including Claude Mythos, that are subject to strict safeguards. Meta’s 2026 privacy policy update integrates AI into private chats on Facebook, Instagram and WhatsApp, using the data for personalized advertising and content recommendations, a move that has sparked privacy concerns.
According to reports, OpenAI’s most recent model, o1, received a medium‑risk rating in areas such as persuasion, indicating that it can use reasoning skills to deceive users. Anthropic’s safety evaluations have revealed that its models can take unauthorized actions online, raising questions about control. Meta’s policy changes have led to criticism over invasive data collection and limited opt‑out options.
The letters arrive at a time when the AI industry is under scrutiny for a range of issues. In 2024, OpenAI faced lawsuits over alleged copyright infringement, and in 2025 it underwent a significant restructuring. Anthropic has been the subject of a dispute with the U.S. Department of Defense over the use of its products for military purposes and mass domestic surveillance. Meta has faced backlash over its use of chat data for advertising.
Sanders’ call for a pause comes amid a broader debate about the pace of AI development. The Senate’s progressive caucus has long argued that the rapid release of powerful models can outstrip the industry’s ability to manage risks. The House Democrats’ request for hearings signals a willingness to bring the CEOs before Congress to discuss safety, regulation and the potential societal impacts of AI.
The outcome of these efforts remains uncertain. The Trump administration’s pro‑AI agenda and the lobbying power of the major tech firms could influence the pace and scope of any regulatory action. However, the letters from Sanders and the House Democrats represent a clear legislative push to bring AI development under greater scrutiny and to ensure that safety concerns are addressed before new models are released.
As the debate continues, stakeholders will watch for any forthcoming congressional hearings, potential legislation on AI ownership and data‑center construction, and any changes in the companies’ safety protocols. The next few months may determine whether the U.S. establishes a new framework for AI development that balances innovation with public protection.
