Senate Approves ChatGPT, Gemini and Copilot for Official Use

The U.S. Senate has officially cleared three major AI chatbots for staff use in a memo dated March 10, 2026.

The Senate Sergeant at Arms' Chief Information Officer approved OpenAI's ChatGPT, Google's Gemini, and Microsoft's Copilot for official work, according to reporting by The New York Times and Business Insider.

The memo outlines permissible uses including research, drafting and editing documents, summarizing information, and preparing briefing materials and talking points for lawmakers.

Microsoft Copilot already integrates with Senate platforms, and the memo notes that data shared with Copilot Chat "stays within the secure Microsoft 365 Government environment and is protected by the same controls that safeguard other Senate data."

The approval reflects how mainstream AI tools have become in professional workplaces, including those handling sensitive government information. However, it's unclear how widely the tools will be adopted across the 100-member chamber, as individual Senate offices and committees often set their own operational policies.

Questions remain about how staffers handling classified information — particularly those on the Senate Intelligence Committee — will approach these tools. A spokesman for Republicans on the intelligence committee did not immediately respond to inquiries about AI usage policies for classified work.

The development follows increased experimentation with AI by lawmakers and staff over the past year, though many have likely been using such tools informally until now.

What this means: The Senate's formal embrace of consumer AI tools marks a milestone in government adoption of the technology. The distinction between Copilot's government-secured environment and the consumer versions of ChatGPT and Gemini will be critical — staff using the latter two will need to be careful about what sensitive data they share.
