ABC's chief white house correspondent Jonathan Karl leading us off. Reporter: The president has repeatedly denied knowing Rudy Giuliani's former associate lev parnas. I don't know him. I don't believe I've ever spoken to him. I don't know parnas, other than I guess I had pictures taken, which I do with thousands of people. Reporter: But ABC news has reviewed a recording of what appears to be a conversation between parnas, the president, and others. A copy of the recording is in the hands of the U.S. Attorney's office in New York. Sources familiar with the recording say it was made in April 2018 at a private dinner at the trump international hotel in Washington. Parnas and the president are heard discussing Ukraine and the American ambassador there, Marie yovanovitch. Parnas tells the president, quote, if you take a look, the biggest problem there, I think where we need to start is we gotta get rid of the ambassador. She's still left over from the Clinton administration. What, the ambassador of the Ukraine? The president responds. Yeah, parnas says. She's basically walking around telling everybody wait, he's gonna get impeached. Just wait. The president appears to say to the group, which sources say included a top aide, quote, get rid of her. Get her out tomorrow. I don't care. Get her out tomorrow. Take her out, okay? Do it. Parnas has described the conversation in recent interview.

The tape that's been released today, in my judgement, will only confirm what people already know, is that the president had concerns and in his authority as president made a decision to make a change. Reporter: Yovanovitch was eventually removed, but not until more than a year after the president's conversation with lev parnas. She said she was never told why she was removed and denies ever telling anyone in Ukraine she thought the president would be impeached. I did not, and I would not say such a thing. Such statements would be inconsistent with my training as a foreign service officer and my role as an ambassador. Reporter: In his phone call with Ukraine's president, president trump called yovanovitch bad news, saying she was going to go through some things. A lot more to come on this. Jon Karl live with us from the white house. Democrats leading the impeachment effort on capitol hill. No surprise here, responding to news of this recording tonight. Reporter: They sure are. House impeachment manager Adam Schiff said this could corroborate much of the evidence they have presented in the impeachment trial. Meanwhile, a very different view from the white house.
