Lieutenant Colonel Vindman has proven to be an American patriot. His firing was a clear and brazen act of retaliation that showcases the President’s fear of the truth — and the vindictiveness which led Republican Senators to be accomplices to President Trump’s cover-up. — Nancy Pelosi (@SpeakerPelosi) February 8, 2020

Vindman was the National Security Council's expert on Ukraine. He testified during the House's public impeachment hearings, detailing his knowledge of President Trump's dealings with Ukraine and its leader. Vindman's testimony, along with the testimony of several other government officials, led to the House Democrats passing two articles of impeachment, moving the proceedings to the Senate for trial.

On Wednesday, Trump was acquitted by the GOP-controlled Senate on both articles of impeachment.

On Friday, Trump removed Vindman and his twin brother who was a lawyer for the NSC as well as ousting Gordon Sondland Gordon SondlandGOP chairman vows to protect whistleblowers following Vindman retirement over 'bullying' Top Democrat slams Trump's new EU envoy: Not 'a political donor's part-time job' Trump names new EU envoy, filling post left vacant by impeachment witness Sondland MORE, who had been the U.S. Ambassador to the E.U.
