A Pentagon spokesperson confirmed that Kacher will “return to service” with the U.S. Navy, when asked by Reuters about his removal from the position on the Joint Staff. Reuters was first to report the decision. Pentagon threatens to cut off Anthropic in AI safeguards dispute, Axios reports “We are deeply grateful for Vice Adm.
