Anthropic on Tuesday asked the U.S. Court of Appeals for the D.C. Circuit to
rehear its Sept. 25 decision that upheld the Trump administration's designation
of Anthropic as a supply‑chain risk to U.S. national security. Anthropic says
the judge misread the law by permitting the Defense Department to act without
any prior designation procedures and alleges the designation was retaliation for
the company's statements on AI safety. The dispute could determine whether
federal authorities or private firms control AI security safeguards during a
critical phase of technology development.
