Third top Pentagon aide Collin Carroll on administrative leave over leaks probe

A third high-level Pentagon staffer has been placed on administrative leave in two days as part of a probe into media leaks.

Colin Carroll, chief of staff to Deputy Secretary Stephen Feinberg, was escorted out of the building on Wednesday, following Dan Caldwell, senior advisor to Secretary Pete Hegseth, and Darin Selnick, deputy chief of staff to Hegseth. 

‘We can confirm that Mr. Carroll has been placed on administrative leave pending investigation. We have nothing additional to provide at this time,’ a defense official told Fox News Digital. 

Carroll did not immediately respond to a request for comment. 

The Pentagon has not provided specifics about what the three officials are accused of leaking. 

Last month Defense Department (DOD) announced it would launch a probe into ‘recent unauthorized disclosures of national security information’ and might employ the use of polygraphs to determine the source of the leaks. 

‘The use of polygraphs in the execution of this investigation will be in accordance with applicable law and policy,’ DOD Chief of Staff Joe Kasper wrote in a memo. ‘This investigation will commence immediately and culminate in a report to the Secretary of Defense.’

He wrote that ‘information identifying a party responsible for an unauthorized disclosure’ would be referred for criminal prosecution.
