According to CBS News, House committees spearheading the impeachment inquiry released on Monday the first transcripts of closed-door depositions in the intensifying probe into President Trump’s dealings with Ukraine. CBS News stated further that:

The Intelligence, Oversight and Foreign Affairs panels released transcripts of hours-long hearings they held with former U.S. Ambassador to Ukraine Marie Yovanovitch and Michael McKinley, a former top aide to Secretary of State Mike Pompeo.

Yovanovitch and McKinley are just two of several current and former Trump administration officials who been summoned to testify as part of the impeachment inquiry, which was formalized through a House resolution last week. Yovanovitch was recalled early from her post in the spring, and McKinley resigned in part over the lack of support for her among State Department officials.

According to PBS, House investigators released more transcripts Tuesday in the impeachment inquiry of President Donald Trump, including hundreds of pages of testimony from two top diplomats deeply involved in the Ukraine matter.

Kurt Volker, the former special envoy to Ukraine, and Gordon Sondland, the U.S. ambassador to the European Union, were involved in White House policy toward Ukraine and aware of the July 25 phone call between Trump and Ukraine President Volodymyr Zelenskiy that’s central to the impeachment inquiry.

[Then] House Democrats on Friday unveiled new details in their impeachment investigation by releasing the interview transcripts from two national security officials who testified about President Trump’s contacts with Ukraine, The Hill reported.

The release of the depositions — providing verbatim exchanges from last month’s private interviews with Lt. Col. Alexander Vindman and Fiona Hill — cap a week in which Democrats have made public several witness transcripts in an effort to keep the attention on their impeachment inquiry even as multiple witnesses have refused to appear. The public phase of the probe is slated to begin next week.
