Trump Administration Forces Anthropic to Shut Down Advanced AI Models Over National Security
The Trump administration ordered AI company Anthropic to disable its two most advanced models, Fable 5 and Mythos 5, on June 13, 2026, citing national security concerns. The directive came after Amazon researchers flagged a potential vulnerability in how the models could analyze cybersecurity code. The models had launched just three days earlier. Unable to comply with export controls limiting access to foreign nationals while operating globally, Anthropic took both models offline worldwide. This marks the first time the U.S. government has used export controls on a commercially available AI model. The action escalates a broader conflict between the Trump administration and Anthropic dating back to February, when the Pentagon pressured the company to remove safety guardrails on its military AI systems. Anthropic has refused, instead insisting on restrictions preventing use in autonomous weapons and mass domestic surveillance. The company characterized the June shutdown as a misunderstanding and says it's negotiating a resolution. The incident has raised international concerns about sovereign AI and sparked debate over balancing national security with AI innovation.

How different outlets framed it
Left-leaning coverage: Progressive critics view the actions as government overreach and retaliation against Anthropic for its principled stance on AI safety. They argue the company is being punished for refusing to remove guardrails on military use and for questioning Trump administration policies. Democratic lawmakers have called the administration's behavior bullying and noted the shutdown represents an unprecedented attack on a U.S. company.
Right-leaning coverage: Defense officials argue the shutdown was necessary to protect against AI-enabled cyberattacks that could compromise military systems and critical infrastructure. They emphasize Anthropic's refusal to provide unrestricted military access and frame safety guardrails as obstacles to national defense. Supporters view the action as protecting American security interests and preventing hostile actors from accessing powerful capabilities.
