Vindman was not “fired,” he was reassigned to the Pentagon. He doesn’t have the right to an NSC position. NSC and Ambassadors serve at the will of the president.

U.S. Ambassador to the European Union Gordon Sondland, who testified about President Trump’s Ukraine dealings during the House impeachment hearings, said Friday that he had been recalled from that position.
“I was advised today that the president intends to recall me effective immediately as United States ambassador to the European Union,” Sondland said.
Sondland’s recall follows the dismissal of another impeachment witness, Lt. Col. Alexander Vindman, who was fired earlier Friday by the National Security Council and escorted off of the White House grounds on Friday.
The moves come just two days after Trump was acquitted in the Senate on two articles of impeachment brought by the House last year over his dealings with Ukraine.
