Things got heated Tuesday at the deposition of Lt. Col. Alexander Vindman, the top Ukraine expert on the National Security Council and the first current White House official to testify in the impeachment inquiry. Sources from both parties, five in all, tell CNN a shouting match erupted during the closed-door session surrounding what Democrats say was a Republican effort to get Vindman to reveal the identity of the whistleblower who first raised alarms about the call between President Trump and his Ukrainian counterpart that is now at the center of the impeachment inquiry. Vindman testified he does not know the whistleblower's identity. Republicans say the Democrats' accusations are incorrect and that they were simply questioning Vindman about people he may have spoken with. Read on for more on that, plus what Democrats are saying about his "disturbing" testimony:
- Democrats' view: "What the Republicans are trying to do in there, very clearly in their questioning, is try to front-door or backdoor Lt. Col. Vindman into revealing who the whistleblower is, even though in his testimony, he said he didn't know," said Democratic Rep. Debbie Wasserman Schultz. "They are trying to, through the back door and through process of elimination by their questions, they are attempting to get him to reveal that, and they have been unsuccessful."
