As Congress confronts AI, Senate lawmakers are shut off from its most advanced tools

A majority of the American public wants Congress to regulate AI . But as policymakers try to make informed decisions, Senate lawmakers and their staff are barred from using all but the most basic AI tools.

According to an internal communication obtained by NPR that was sent to Senate staff in the spring by the sergeant at arms, who oversees cybersecurity in the chamber, Senate staff have access to three AI chat interfaces at no cost to their offices: Microsoft Copilot Chat, Gemini Chat for Google Workspace Enterprise Plus and OpenAI ChatGPT Enterprise.

But in an apparent effort to balance innovation with risk, the sergeant at arms has not currently authorized any of the more advanced AI tools that are at the center of regulatory discussions in Washington, as well as recent public debate about AI development and safety. That debate has been prompted in part by AI industry leaders' own warnings .

These more capable tools, like OpenAI's Codex or Anthropic's Claude Code and Cowork, allow "agents" powered by advanced AI models to complete tasks autonomously at a user's request — and can be powered by models of varying cost and capabilities.

"Congress, unfortunately, has always lagged behind," said Adam Kovacevich, the founder and CEO of center-left tech industry policy group Chamber of Progress. "Right now you've got lawmakers writing rules for technology they, in many cases, never even used and that's a problem."

The agentic tools, which can be given varying levels of access to a computer's files, are considered more capable than the web-based chat interfaces that Senate staff currently have access to. The rules from the sergeant at arms state that "platforms cannot independently access internal Senate drives, shared folders, email, Teams chats, or other Senate resources."

While outside experts acknowledge there are risks of a broader embrace of AI tools by Congress, they say limiting access also has its drawbacks.
