From N.Y. Times account of Lev Parnas-supplied phone video of a chat he and President Trump (along with others) had during April 2018 about the purportedly disloyal Marie L. Yovanovitch, who was then ambassador to Kyiv.
The part you want to listen to starts at the 3:35 mark.
Parnas: “The biggest problem there, I think, where we, where you, need to start is we gotta get rid of the ambassador. She’s basically walking around telling everybody, ‘Wait, he’s gonna get impeached, just wait.’”
Trump (following some wallah-wallah): “Get rid of her. Get her out tomorrow. I don’t care. Get her out tomorrow. Take her out. Okay? Do it.”
Times: “Yovanovitch remained in her job for another year after Mr. Trump’s remarks until she was recalled on the White House’s orders, according to testimony in the impeachment inquiry. It is not clear whether the president changed his mind, forgot about his order or was talked out of dismissing her.”
