An advisor to Defense Secretary Pete Hegseth was put on leave for leaking.

Dan Caldwell was escorted out of the Pentagon on Tuesday for "an unauthorized disclosure," according to Reuters.

Details of the unauthorized disclosure are unclear.

According to Reuters, this comes after a March 21 memo ordering a Pentagon investigation into leaks ordered by Pete Hegseth's chief of staff.

Reuters reported:

One of U.S. Defense Secretary Pete Hegseth's top advisors, Dan Caldwell, was escorted out of the Pentagon on Tuesday after being identified during an investigation into leaks at the Department of Defense, a U.S. official told Reuters.

Caldwell, a senior advisor to Pete Hegseth, was placed on administrative leave for "an unauthorized disclosure," the official said, speaking on condition of anonymity. The decision has not been previously reported.

"The investigation remains ongoing," the official said.

Dan Caldwell was also part of the Mike Waltz Houthi Signal chat group.

It will be interesting to see if his removal was also tied to that incident.
