Three Pentagon officials fired amid leak investigation: Politico
In March, Hegseth’s chief of staff, Joe Kasper, called for an investigation into “unauthorized disclosures” of national security information with those found responsible to “be referred to the appropriate criminal law enforcement entity for criminal prosecution.”

Three Pentagon officials were fired on Friday amid a probe into leaks while Defense Secretary Pete Hegseth's chief of staff will leave his position for a new role at the department, Politico reported.
Senior advisor Dan Caldwell and Hegseth's deputy chief of staff, Darin Selnick, have been terminated, the report said, citing people familiar with the matter. The third is Colin Carroll, who is the chief of staff to Deputy Defense Secretary Stephen Feinberg, it said.
All three were put on administrative leave earlier in the week.
In March, Hegseth's chief of staff, Joe Kasper, called for an investigation into "unauthorized disclosures" of national security information with those found responsible to "be referred to the appropriate criminal law enforcement entity for criminal prosecution."
The probe came after the New York Times reported that Elon Musk was to get a top secret briefing about the US military's planning for any potential war with China. The Times cited multiple unidentified US officials familiar with the matter, while President Donald Trump and Hegseth denied any plans for Musk to get such a high-level briefing.
The three officials who were fired and Kasper declined to comment to Politico, while the Pentagon didn't respond to the outlet.
