Dan Caldwell, a senior adviser to Defense Secretary Pete Hegseth, has been placed on administrative leave and removed from the Pentagon following the launch of an internal probe into classified information leaks. The investigation was triggered by concerns over recent unauthorized disclosures within the Department of Defense.
Caldwell, a Marine Corps veteran with a background in military advocacy and national security policy, had been actively involved in high-level operational planning. His recent responsibilities included coordinating with the National Security Council during strategic discussions on military action in the Middle East.
Officials have not specified the exact nature of the leaked information or confirmed Caldwell’s direct involvement, but his removal is part of a broader effort to tighten internal security and root out sources of unauthorized disclosures.
The review remains ongoing, and it is currently unclear if Caldwell will face additional disciplinary action or legal consequences. The Pentagon has not issued a formal comment on the specifics of the case.
