2 Pentagon officials fired amid sweeping leak investigation

The week of turmoil affecting the Pentagon's inner circle continued Friday, when two political appointees suspended earlier this week were terminated, multiple officials told CBS News. 

Secretary of Defense Pete Hegseth's chief of staff Joe Kasper ordered an investigation into unauthorized disclosures in March. His memo said the investigation would seek "a complete record" of leaks and use polygraph tests if necessary. 

The two now-fired officials are Hegseth's senior advisor Dan Caldwell and deputy chief of staff Dan Selnick, the sources said. Both were put on administrative leave earlier this week pending the leak investigation, CBS News reported. Politico was first to report their termination.
