“He was very insubordinate, reported contents of my 'perfect' calls incorrectly, & was given a horrendous report by his superior,” Trump said about Vindman, seemingly referring to November impeachment testimony given by NSC official Tim Morrison, Vindman’s supervisor, who said he had “concerns” about the decorated war veteran's judgment and suggested he wasn’t “cut out” for policymaking.

Vindman rebutted Morrison’s assessment in his testimony, saying the two had not worked together long and that his military background might have played a role in the determination. Morrision departed from his position during the House’s investigation.

Pressman also called out lawmakers for being “silent” while Trump “continues his campaign of intimidation."

Vindman — along with impeachment witness Gordon Sondland, the U.S. Ambassador to the European Union — was removed from his White House post on Friday during a purge characterized as “payback” by White House officials against those who testified against the president.

Others, including former U.S. envoy to Ukraine Marie Yovanovitch and former top U.S. envoy to Ukraine Bill Taylor, have left their posts in recent days.
