Technology Defense

Event Summary

A legal dispute is ongoing between the United States — United States Department of Defense>>> and technology company Anthropic>>>. The Pentagon, under Defense Secretary Pete Hegseth>>>, designated Anthropic>>> as a national security supply-chain risk, leading to former President Donald Trump>>> ordering federal agencies to cease using its technology. Anthropic>>> claims this designation is unlawful retaliation for raising ethical and safety concerns about AI usage in war, and has filed lawsuits in Washington, D.C., and San Francisco. Judges on the United States — United States Court of Appeals for the Third Circuit>>> appear divided on the matter, with Judge Karen L. Henderson>>> calling the Pentagon's action an 'overreach' and Judge Neomi Rao>>> questioning the court's ability to second-guess the Secretary's judgment. A federal judge in San Francisco previously ruled in Anthropic>>>'s favor, blocking the designation.
