Bipartisan House Members Demand Lutnick Explain Legal Basis for Anthropic Fable 5 Export Controls

A bipartisan group of House lawmakers sent a formal letter to Commerce Secretary Lutnick demanding the legal and technical rationale behind the decision to block foreign nationals from accessing Anthropic's Fable 5 and Mythos 5, warning the action 'may have opened a precedent with significant implications for the AI industry.' The letter specifically pressed Lutnick on what statutory authority he invoked when ordering Anthropic to restrict foreign nationals from accessing an AI API rather than controlling physical goods or code exports. The congressional inquiry escalates oversight pressure on the first-ever US government shutdown of commercial AI models under export control law.
