I DON’T THINK MATTIS HAS EVER HAD RESPECT FOR THE CHAIN OF COMMAND.
The Commander-in-Chief is the President - which Mattis ignored and still does.
Mattis worked for the President. In his resignation letter letter never mentioned that. He mentioned the troops but never acknowledged the man he worked for.
Trump fired him because after giving him 9 months to come up with a withdrawal plan for troops in the Middle East, Trump came to learn that Mattis totally ignored that “order” and that Mattis acted as though the President worked for him.
Mattis, you are a low-life, insubordinate, disloyal douchebag.
Mattis worked for the American people and the Constitution and was legally bound to support the President that the American people had lawfully elected.
