Trump Halts Anthropic AI Use by Federal Agencies, Citing National Security Risk

• President Trump orders federal agencies to immediately stop using Anthropic AI technology.
• Agencies have six months to remove Anthropic tools from sensitive military and intelligence operations.
• The decision stems from Anthropic's refusal to grant the Pentagon unrestricted access to its Claude model for certain missions.
• Defense officials labeled Anthropic a "supply chain risk to national security" after the dispute.
• Anthropic plans to challenge the designation in court, calling it an extraordinary move without legal grounding.
