Dan Caldwell, a senior adviser to US Defense Secretary Pete Hegseth, was escorted out of the Pentagon on Tuesday as part of a probe into leaks at the Defense Department

A top adviser to Defense Secretary Pete Hegseth was placed on administrative leave Tuesday after being identified in a Pentagon investigation into intelligence leaks, two U.S. defense officials confirmed to the Daily Caller News Foundation.

The Pentagon’s internal watchdog notified the defense secretary of a probe into whether he shared classified information last month in a Signal group chat that included a journalist.
