His departure comes during a week of major turmoil at the Pentagon.
Dan Caldwell, Darin Selnick, and Colin Carroll were placed on leave during a leak investigation.

Politico reports:
Joe Kasper, Defense Secretary Pete Hegseth’s chief of staff will leave his role in the coming days for a new position at the agency, according to a senior administration official, amid a week of turmoil for the Pentagon.
Senior adviser Dan Caldwell, Hegseth deputy chief of staff Darin Selnick and Colin Carroll, the chief of staff to Deputy Defense Secretary Stephen Feinberg, were placed on leave this week in an ongoing leak probe. All three were terminated on Friday, according to three people familiar with the matter, who, like others, were granted anonymity to discuss a sensitive issue.
The latest incidents add to the Pentagon’s broader upheaval in recent months, including fallout from Hegseth’s release of sensitive information in a Signal chat with other national security leaders and a controversial department visit by Elon Musk.
Caldwell, Carroll, and Selnick and Kasper declined to comment. The Pentagon did not respond to a request of comment.
Kasper had requested an investigation into Pentagon leaks in March, which included military operational plans for the Panama Canal, a second carrier headed to the Red Sea, Musk’s visit and a pause in the collection of intelligence for Ukraine.
