Anthropic will sue the U.S. Department of Defense.

Anthropic has vowed to challenge the U.S. Department of Defense's decision to blacklist it in court, after the latter claimed the company refused to lift all restrictions on the military's use of its Claude model. The company also said it was "deeply saddened" by the escalating dispute. This cutting-edge artificial intelligence company is doing what few other companies have done since Trump returned to the White House: directly and openly challenging the Trump administration. Trump and Defense Secretary Hergesse threatened earlier Friday to cut off Anthropic from numerous customers through a "supply chain risk" designation, a practice historically reserved for "foreign adversaries." Anthropic stated, "No matter how the 'Department of War' intimidates or punishes us, it will not change our position on mass surveillance or fully automated weapons." "We will challenge any supply chain risk designation through legal means." (Jinshi)
