So you think what Trump and his people did is okay??? And all people that testify to abuse of power should be expected to be unfairly punished?

Why do you always jump to such extreme conclusions when I say anything?  He quit and took retirement. He was not dishonorably discharged.  I never said what you said I said. So now he gets retirement pay and can start another career.  He will be financially ahead by leaving.

The other thing not mentioned is that he received a promotion and retired two days later, which is what he wanted and pushed for.  Had he stayed his assignment would not have been a job he wanted.  So, in the end it was his choice to leave and he is still complaining about it.

I believe his promotion was delayed.  

It was but it happened. Interesting only Fox reported it happened. I looked for other references

But Esper signed off on Vindman’s promotion to colonel on Monday, a senior defense official confirms to Fox News, two days before the Army officer announced his retirement.

I found a wealth of articles on this.  I believe he was approved for the promotion but whether DT signed it isn't clear.  The articles are all over the place - they all agree he was approved, none say the President signed it.  Since it all happened a couple days ago, more info may show up later
