IRT John Toillion: [You say, "It’s obvious she does not agree with the former and current commander-in-chiefs’ positions on military engagement around the world. As the saying goes, “You cannot serve two masters.”

Further, she took an oath when commissioned to “support and defend the Constitution of the United States against all enemies, foreign and domestic.”  ]

Are you saying that one should ignore one's principals to obey the commander-in-chief, to goose-step mindlessly along with him?  Additionally, you are equating defending the constitution with defending trump's actions.  Wake up!  trump is the real enemy of the constitution.
