Trump dismisses Alexander Vindman, Yevgeny Vindman, and Gordon Sondland
The chief executive has the perfect right to fire disloyal employees, and a commander-in-chief to reassign insubordinate officers, yet, leftists are up in arms.
President Donald Trump emerged victorious from the Democrats' ill begotten impeachment debacle. The losers destined to be removed from their positions — were Alexander Vindman and his twin brother Yevgeny, both of whom are out at the National Security Council, and ambassador (now former ambassador) to the European Union Gordon Sondland.
All three serve at the president's pleasure. Under the Constitution, Trump is responsible for foreign policy and is commander in chief. In the former role, he has wide latitude to choose and dismiss ambassadors. In the latter role, thousands of years of military tradition hold that officers can be dismissed — or worse — for insubordination.
Sondland is merely weak, but Alexander Vindman is a genuine piece of work. The fact that his commanding officer has a constitutional right (and duty) to set foreign policy did not weigh at all with him. He felt that, as a decorated bureaucrat, his opinion matter more.
When the president ignored Vindman's opinion, the latter violated national security to complain about Trump's chosen policy approach. Then, when called before Congress, the man who wears a suit to work showed up in his uniform, evidently trying to put the military's imprimatur on his personal mutiny.
Kentucky Rep. Tom Massie understands the dynamics:

I’d fire him. I listened to his testimony in the SCIF. He’s a leaker, not a whistleblower. Vindman was upset that
@realDonaldTrump didn’t follow the script Vindman prepared for the phone call. Current Commander in Chief doesn’t take orders from a Lt. Col.!

Nancy Pelosi was shocked, shocked, that an insubordinate officer who leaked like a sieve could be reassigned to a position where he could do no damage.
