Pentagon Advisor Suspended During Leak Investigation

The Department of Defense has placed Dan Caldwell, a senior adviser to Defense Secretary Pete Hegseth, on temporary leave as an inquiry into a potential security breach unfolds. A Pentagon spokesperson confirmed his removal from duties on Tuesday.

Joe Kasper, Chief of Staff to Hegseth, circulated a directive in late March instigating a probe into unauthorized information leaks, with provisions to employ polygraph tests when deemed necessary.

The release of Caldwell's administrative leave status was initially reported by Reuters.

According to insiders, Caldwell is alleged to have improperly shared sensitive materials with members of the media.

Before his role at the Pentagon, Caldwell held positions at Defense Priorities and Concerned Veterans for America, organizations linked to both foreign policy and veteran affairs, where Hegseth once held a leadership role. Caldwell is also a Marine Corps veteran with combat experience in Iraq.

In an article by The Atlantic, Caldwell was identified as a communicator on behalf of the Defense Department in discussions related to operations concerning the Houthis.

The Kasper memo emerged concurrently with strong denials from both the Pentagon and White House about reports of certain individuals, such as Elon Musk, visiting for briefings on hypothetical military engagements with China. Elon Musk's official role, despite no formal government position, was outlined as an active contributor in the current administration.
