He got fucking dragged by Trumpworld after he resigned over Trump's stance on Afghanistan (or was it the Kurds?), it was probably one of the most severe about-faces I've ever seen from conservatives about one man. Went from a Marine's Marine, a warrior-scholar, to a complete disgrace to the Corps as far as they're concerned.
Really cemented my view of Trump as a cult of personality when I saw that narrative, and the base eating it up, in real time.
