Former US Ambassador to Ukraine Marie Yovanovtich testified that Mike McKinley, a former senior adviser to Secretary of State Mike Pompeo, reached out to her after the release of the July 25 call.

“He wanted to see how I was doing, and he was concerned there had been no outreach and no kind of public support from the Department,” she said, according to the transcripts.

At that point, McKinley was still at the State Department. Yovanovitch said that McKinley called to give her a heads up about his resignation. He told that he told her he was leaving because "he was concerned about how the Department was handling, you know, this cluster of issues.”

“I think he felt that the Department should stand by its officers,” she said, adding that he was referring to her and “perhaps George Kent as well.” Kent, a deputy assistant Secretary of State for European and Eurasian affairs, also testified in the inquiry.

Yovanovitch went on to say that McKinley told her “there had been a difficult conversation with the State Department lawyers and that George had shared that with him.” She said it was related a “disagreement” to the subpoena for documents.

“He said that there had been an argument and that he was going to, you know, share this further up, is what he said — I don't know what ‘up’ means or who that means — and that because he didn't feel that ostracizing employees and bullying employees was the appropriate reaction from the Department,” Yovanovitch said.

Yovanovitch said she did not know if the disagreement was about whether the State Department should produce the documents, if Kent was arguing for the production of documents, or if it was related to whether Kent should testify to the committees.
