Top defense advisor Dan Caldwell has been removed amid a major leak investigation tied to classified military operations and a Signal chat breach.
The probe began after a journalist was mistakenly added to a secure group chat discussing U.S. airstrikes, exposing Caldwell’s involvement.
The Pentagon has responded with polygraph tests and strict new security protocols in its toughest internal crackdown in decades.
Caldwell now faces possible criminal charges, marking a dramatic fall and signaling the Trump administration’s hardline stance on internal dissent.
