WASHINGTON — A U.S. Army officer who works at the White House National Security Council said he listened in on the call between President Donald Trump and Ukraine's president and was so disturbed by the content that he reported his concerns to the NSC's legal counsel.
Lt. Col. Alexander Vindman said in a statement prepared for the House impeachment inquiry that the call was just one of the instances he witnessed in which Trump administration officials repeatedly conditioned aid to Ukraine on that country agreeing to investigate former Vice President Joe Biden.
His statement corroborates the complaint made by a whistle-blower in the intelligence community, whom Trump has repeatedly sought to discredit and dismiss. Vindman's testimony is scheduled to be delivered Tuesday to the three House committees leading an impeachment inquiry of Trump and provides a key piece of evidence from someone with first-hand knowledge of the events being investigated.
