# Senate to add Claude to staff AI tools

Full title: US Senate is expected to add Anthropic's Claude to the AI tools approved for staff

Bloomberg Government and then Politico (Oct 15, 2026; two people familiar) reported that the US Senate is expected to give staffers access to Anthropic's Claude for official work, alongside ChatGPT, Gemini and Copilot, which the Senate Sergeant at Arms already allows. No start date was given; the Sergeant at Arms and Anthropic did not comment.

## Key facts
- Sources: two people with knowledge of the matter (Politico, Owen Dahlkamp, Oct 15); Bloomberg Government reported it first
- Already approved: Senate Sergeant at Arms Jennifer Hemingway testified in April that staff had access to Microsoft Copilot, OpenAI ChatGPT and Google Gemini
- Bloomberg Government headline: 'Senate staff clamor for access to Anthropic's Claude chatbot'
- Timing unknown; individual offices decide how to use the tools

## What happened

The Senate is expected to add Claude to the AI chatbots its staff may use with Senate data, according to two people familiar
with the plan quoted by Politico; Bloomberg Government reported the plan first. Staff can already use ChatGPT, Gemini and
Copilot. No date was announced.

## Why it matters

Legislative staff who draft AI rules will use the tools of the companies they regulate. The Bloomberg Government story was read
only as a headline (paywalled).
