Shakeup at the Pentagon: Hegseth Aides Fired Amid Leak Investigation
In a dramatic turn of events at the Pentagon, three aides to Defense Secretary Pete Hegseth have been officially terminated following a probe into unauthorized leaks. This recent shakeup underscores the ongoing turmoil within the Department of Defense.
On Friday, reports surfaced that Chief of Staff Joe Kasper was stepping down amid the fallout from the investigation, which has already seen significant personnel changes. Earlier this week, an advisor to Hegseth was placed on leave after being implicated in leaking sensitive information.
Dan Caldwell, who was previously involved in the Mike Waltz Houthi Signal chat group, faced immediate removal from the Pentagon on Tuesday due to what Reuters described as an “unauthorized disclosure.”

Alongside Caldwell, Deputy Chief of Staff Darin Selnick and Colin Carroll, who served as chief of staff to Deputy Secretary of Defense Stephen Feinberg, were also placed on leave and subsequently escorted out of the Pentagon.
According to Politico, all three aides—Caldwell, Selnick, and Carroll—were officially terminated on Friday. Notably, Selnick and Carroll are reportedly considering legal action for wrongful termination, as detailed in the report.
Interestingly, Kasper is said to have harbored a “deep vendetta” against the trio, creating an atmosphere ripe for conflict, as noted by Fox News. This vendetta raises questions about the motivations behind such drastic personnel decisions.
Kasper was at the forefront of the internal investigation into the leaks, which have been described as serious in nature. “This is not about interpersonal conflict,” a Pentagon official clarified to Fox News. “There is evidence of leaking. This is about unauthorized disclosures, up to and including classified information.”
As reported by Politico, the series of events has contributed to a broader upheaval within the Pentagon, which has faced several controversies in recent months. These include the fallout from Hegseth’s release of sensitive information during a Signal chat with other national security figures, as well as a contentious visit by Elon Musk to the department.
Caldwell, Carroll, Selnick, and Kasper have all refrained from commenting on the situation. However, two sources close to the matter indicated that Carroll and Selnick are planning to pursue a lawsuit for wrongful termination, seeking to challenge their abrupt exit from their posts. The Pentagon has yet to respond to inquiries regarding the situation.
