Follow Up Letter Calls on OMB to Block Grok Implementation

WASHINGTON, D.C. — In a follow up letter organized by Public Citizen, over 20 organizations called on the Office of Management and Budget (OMB) to suspend the deployment of Grok, the large language model (LLM) developed by xAI. This is a second coalition letter following the group’s original calls on the OMB to block the implementation of Grok across federal agencies. The new letter comes in response to the General Services Administration (GSA) entering into a government-wide agreement under its OneGov strategy to make Grok available to all federal agencies.

The original letter cites concerns over Grok’s lack of objectivity, documented use of hate speech, and lack of any safety testing. In the letter sent today, the groups urged OMB to:

• Issue immediate guidance suspending the federal deployment of Grok
• Publicly clarify whether Grok has been evaluated for compliance with Executive Order 14319’s neutrality and truth-seeking standards.
• Ensure transparency by requiring publication of any safety tests, red-teaming results, or risk assessments conducted on Grok.
• Provide an explanation of how the GSA’s contract for Grok can be reconciled with the Trump Administration’s own requirements for AI neutrality and accuracy.

“AI systems that distort facts or amplify hate have no place in democratic governance,” said J.B. Branch, a Big Tech accountability advocate at Public Citizen. “Grok’s federal deployment is a credibility crisis. Public trust in AI governance begins with truth. The administration can’t preach AI neutrality and accuracy while contracting with a model that spreads hate, conspiracies, and falsehoods. Deploying Grok throughout the federal government sends the message that ideology matters more than integrity.”

The letter affirms that the usage of LLM’s such as Grok at the federal government undermines:

• Public trust: Due to the documented ideologically biased, inaccurate, and conspiratorial content that AI systems are known to produce, the public cannot be confident in the federal adoption of these systems.
• Institutional integrity: Furthermore, Grok itself is in violation of the Administration’s own policies under Executive Order 14319, as well as the OMB’s guidance. The letter states, “On the one hand, the administration has established strict principles requiring neutrality, factual accuracy, and risk mitigation in AI systems. On the other hand, the government has entered a multi-year contract granting Grok access to every federal agency despite its repeated and documented failures to meet these requirements.”
• Democratic governance: Lastly, the lack of objectivity and ideological neutrality in LLM’s such as Grok endangers institutional integrity.
