WASHINGTON — Sen. Bernie Sanders and Steve Bannon, figures from opposite ends of the American political spectrum, are set to share a stage Tuesday at an event calling for faster action to regulate artificial intelligence. Sanders, an independent senator from Vermont, and Bannon, a former adviser in the Trump White House, will appear at the all-day “Pro-Human Assembly” in Washington, D.C. The gathering is intended to build pressure on Congress to address AI’s effects on workers, families and society while keeping people in control of the technology. The event is being organized by the Future of Life Institute, a nonprofit advocacy group that released 33 principles for its pro-human movement in March. The principles say humans should remain in charge of AI, retain personal agency and liberty, and be able to hold AI companies accountable. The unusual alliance comes amid growing concern about the rapid expansion of AI and the infrastructure needed to run it. Communities across the country are debating the construction of large data centers, which can increase demand for electricity and place pressure on utility systems. The House is expected to consider the Ratepayer Protection Act as early as Tuesday. The legislation would seek to protect consumers from higher energy costs connected to data-center construction. House Speaker Mike Johnson, a Louisiana Republican, has said he supports some safeguards but believes technology companies, rather than Congress, should take primary responsibility for safety. He has opposed a moratorium on AI development, arguing that slowing the United States could allow China to gain an advantage. “We cannot put a moratorium on this because China will overlap us,” Johnson said over the weekend. “If Congress just races in and does some sort of emergency session to try to regulate AI, we will lose the race to China.” President Donald Trump has also promoted AI and data centers and has rejected warnings from technology executives who have called for a slower pace of development. Trump said the United States is the world’s most advanced country in AI and argued that the nation must maintain its lead, while allowing for some guardrails. The push for stronger controls has gained support from some industry leaders. Executives at Anthropic and OpenAI have called for slowing development to keep AI under human control, following warnings from researchers about potential safety risks. The Washington gathering will include a broad range of participants, including actors Ashley Judd and Joseph Gordon-Levitt, religious leaders and child-safety advocates. Some of the advocates are parents whose children died by suicide after communicating with AI chatbots. Organizers said the event would seek to create a shared space for cooperation across political and religious differences. The pairing of Sanders and Bannon underscores how concerns about AI are disrupting traditional political alliances, even as policymakers remain divided over how much authority the federal government should exert over the industry.
