The Democrat-led impeachment inquiry hearings are ongoing in the House (still behind closed doors for now), and one witness making a statement was former ambassador to Ukraine from 2016 until May of this year, Marie Yovanovich:

The former United States ambassador to Ukraine told impeachment investigators last month that she felt “threatened” by President Trump after it emerged that he told the Ukrainian president she would “go through some things,” adding that she still feared retaliation. That was just one detail that emerged Monday as the House released hundreds of pages of testimony from Marie L. Yovanovitch, who was abruptly recalled in May and remains a State Department employee, and Michael McKinley, a top diplomat who advised Secretary of State Mike Pompeo and has since retired.

However, on his Fox News show, Tucker Carlson said there seem to be irregularities in Yovanovich’s testimony vs. other documentation. Watch:

From GOP Rep. Lee Zeldin:

It appears Ambassador Yovanovitch did not accurately answer this question I asked her during her “impeachment inquiry” deposition under oath. https://t.co/2Ju420Pkpb pic.twitter.com/WACsyksMzW — Lee Zeldin (@RepLeeZeldin) November 8, 2019

The Federalist’s Sean Davis adds:

Here's the specific exchange between Yovanovitch and @RepLeeZeldin, in which Yovanovitch clearly denies ever responding to the Democratic House committee staffer: "I didn't respond to that e-mail, because I had already transferred everything to [State]." https://t.co/4z4BNGQQbW pic.twitter.com/hp3uSG8NTo — Sean Davis (@seanmdav) November 8, 2019

Won’t it be ironic if Rep. Schiff ends up helping get some of his own witnesses caught in his trap that’s meant for Trump?

LOL Schiff's first star witness for muh public impeachment hearings is a perjurer. Perfect. ? https://t.co/dI2Mku1sd4 — ?? Building Trumpmore⚒️ (@k_ovfefe) November 8, 2019

According to Roll Call, “Yovanovitch is scheduled for public testimony on Friday, Nov. 15.”

Unless something changes, of course.
