Something Vindman would know, since he had sworn to defend the Constitution. Which means Vindman violated his oath in trying to undermine the President's foreign policy.
In a just and ideal world, he will be swept up along with his co-conspiators like Obama, Lynch, Brennan, Comey, McCabe, Clapper etc. for trying to obstruct Trump from even before the election, right until today.
In reality, I doubt that Barr, Horowitz and Durham will be able to do much.
Trump was elected for his foerign policy agenda.
This guy should be considered, for Courts Martial
I would like to hear testimony from his superiors, about the assignment, orders and parameters, he was working under.
