The findings underscored what advocates described as a pattern of racist, antisemitic, and conspiratorial behavior.
“Grok has shown a repeated history of these meltdowns, whether it’s an antisemitic meltdown or a racist meltdown, a meltdown that is fueled with conspiracy theories,” Public Citizen’s big-tech accountability advocate J.B. Branch told Decrypt.
The new warning followed letters that Public Citizen and 24 other civil rights, digital-rights, environmental, and consumer-protection groups sent to the OMB in August and October, urging the agency to suspend Grok’s availability to federal departments through its General Services Administration, which manages federal property and procurement. The group said no reply followed from either outreach.
Despite repeated incidents, Grok’s reach inside government has grown over the past year. In July, xAI secured a $200 million Pentagon contract, and the General Services Administration later made the model available across federal agencies, alongside Gemini, Meta AI, ChatGPT, and Claude. The addition came at a time when U.S. President Donald Trump ordered a ban on "woke AI" in federal contracts.
Advocates said those moves heightened the need for scrutiny, particularly as questions mounted about Grok’s training data and reliability.
“Grok was initially limited to the Department of Defense, which was already alarming given how much sensitive data the department holds,” Branch said. “Expanding it to the rest of the federal government raised an even bigger alarm.”
Branch said Grok’s behavior stemmed in part from its training data and the design choices made within Musk’s companies.
“There’s a noticeable quality gap between Grok and other language models, and part of that comes from its training data, which includes X,” he said. “Musk has said he wanted Grok to be an anti-woke alternative, and that shows up in the vitriolic outputs.”
Branch also raised concerns about the model’s potential use in evaluating federal applications or interacting with sensitive personal records.
“There’s a values disconnect between what America stands for and the type of things that Grok is saying,” he said. “If you’re a Jewish individual and you’re applying for a federal loan, do you want an antisemitic chatbot potentially considering your application? Of course not.”
Branch said the Grok case exposed gaps in federal oversight of emerging AI systems, adding that government officials could act and remove Grok from the General Services Administration’s contract schedule at any time—if they chose to.
“If they’re able to deploy National Guard troops throughout the country at a moment’s notice, they can certainly take down an API-functioning chatbot in a day,” he said.
