Below is story from NYTimes. I thought closed door meant not for public release. This sounds like a blow by blow rendition of her testimony.
In a closed-door deposition that could further fuel calls for Mr. Trump's impeachment, Ms. Yovanovitch delivered a scathing indictment of how his administration conducts foreign policy. She warned that private influence and personal gain have usurped diplomats' judgment, threatening to undermine the nation's interests and drive talented professionals out of public service. And she said that diplomats no longer have confidence that their government "will have our backs and protect us if we come under attack from foreign interests."
According to a copy of her opening statement obtained by The New York Times, Ms. Yovanovitch said she was "incredulous" that she was removed as ambassador "based, as far as I can tell, on unfounded and false claims by people with clearly questionable motives."
