TRUMP SAYS HE MIGHT STOP OFFICIALS LISTENING IN ON HIS CALLS WITH FOREIGN LEADERS AFTER 'INSUBORDINATE' VINDMAN'S TESTIMONY

After the president's acquittal of impeachment charges in the U.S. Senate, Trump fired both Vindman, as well as U.S. Ambassador to the European Union Gordon Sondland. Both men had testified against Trump during the impeachment hearings.

"Vindman was a guy that when we took him out of the building, the building applauded," Trump said of Vindman's dismissal. "Many of the people in the building started applauding."

"I'm not a fan of Vindman," Trump added. "I don't think I've ever met him, by the way. Just so you understand, many of these people I've never met. But I'm not a fan of Vindman, no question about it."

Vindman was the leading expert on Ukraine at the NSC before being ousted by the Trump administration in a move many observers believed was retribution for his testimony.

After Vindman's dismissal, his attorney David Pressman said in a February statement, "There is no question in the mind of any American why this man's job is over, why this country now has one less soldier serving it in the White House. LTC Vindman was asked to leave for telling the truth. His honor, his commitment to right, frightened the powerful."
