Former Trump AI adviser warns Anthropic ban could harm US AI sector

In short: A former Trump White House AI adviser says the administration’s crackdown on Anthropic could hurt US AI leadership and investment.

What happened

Dean Ball, who previously advised the Trump White House on AI and left in July 2025, criticized the administration’s dispute with Anthropic. He called it “the most heavy-handed attack on the private sector in generations,” and said it weakens the United States in AI.

The conflict grew out of Pentagon contract talks. Anthropic wanted limits that would block its Claude AI models from being used for fully autonomous weapons (weapons that can select and attack targets on their own) and for mass domestic surveillance (broad monitoring of people inside the US). The Department of Defense pushed for “all lawful uses” without those limits.

On February 27, 2026, President Trump posted on Truth Social telling federal agencies to “IMMEDIATELY CEASE all use of Anthropic’s technology.” Defense Secretary Pete Hegseth then posted on X that Anthropic had been labeled a “Supply-Chain Risk to National Security.” That label bars military contractors from doing commercial activity with Anthropic, with a six month transition period.

OpenAI later secured the Pentagon deal Anthropic lost, although CEO Sam Altman called the situation “opportunistic and sloppy” amid backlash.

Why it matters

Ball and other critics warn the move could scare off money and partners, like telling businesses a major supplier is suddenly off-limits (like a store being told it cannot buy from a popular brand anymore). They also argue the label is unusual for a US company, could be legally challenged, and sets a precedent for government punishment announced through social media.
