Sen. Warner Proposes Mandatory Testing for Advanced AI Models

Sen. Mark Warner is introducing a multi-bill legislative framework that would impose mandatory government testing on the nation's most powerful AI systems and create new transparency requirements for the data centers that train them.

The centerpiece is the Secure AI Development Act, which would establish a testing protocol for frontier AI models before they can be deployed. The legislation would also create a voluntary system for reporting AI safety incidents.

Why it matters

Warner's proposal represents one of the most detailed AI regulatory frameworks from a senior Democrat with national security oversight. As vice chair of the Senate Intelligence Committee, he brings credibility on threat assessment — and his timing reflects growing bipartisan concern that voluntary industry commitments aren't sufficient to manage risks from increasingly capable AI systems.

The broader package

Beyond model testing, Warner's legislative agenda spans the AI value chain:

Data center accountability: Large facilities would need to disclose energy and water consumption, with certain federal tax benefits contingent on meeting sustainability benchmarks. This provision directly addresses concerns in Warner's home state of Virginia, which hosts the country's densest concentration of data centers and has maintained a long-standing tax exemption for the industry.

Consumer and market protections: The package includes rules governing consumer-facing AI agents and would prohibit federal agencies from purchasing AI systems capable of generating child sexual abuse material. Financial regulators would be required to address risks from AI-generated content that could destabilize markets.

Workforce transition: A new fund would support workers displaced by AI, financed by limiting certain tax breaks currently available to AI data centers.

Political context

Warner has made AI a defining issue in his reelection campaign, positioning himself between progressive calls for data center moratoriums and industry resistance to new regulations. Virginia faces mounting political pressure over data center expansion, with state lawmakers considering whether to repeal existing tax exemptions.

In prepared floor remarks, Warner will acknowledge public anxiety about AI's trajectory while rejecting calls to halt development. "We're not putting this genie back in the bottle," he plans to say, warning that "the amount of disruption this technology will bring over the next five years is, frankly, beyond jaw-dropping."

He will frame his approach through a national security lens, arguing that "our greatest national security failures often come when we recognize a threat but fail to act until after a crisis."
