NBC News reports:
The fast-moving impeachment inquiry into President Donald Trump, stemming from the president’s dealings with Ukraine, involves numerous hearings, depositions and subpoenas of present and former top administration officials and other figures — and more than a few presidential tweets. Several Trump administration officials are scheduled to appear for depositions next week as part of the impeachment inquiry, according to two Hill staffers.
They include: Kathryn Wheelbarger, acting assistant secretary of defense for security affairs, Philip Reeker, acting assistant secretary of European affairs, Alexander Vindman, director of European affairs at the National Security Council, Timothy Morrison, top Russia adviser at the National Security Council; and Suriya Jayanti, a foreign service officer in Kiev. Acting U.S. ambassador to Ukraine Bill Taylor is already scheduled to testify before House investigators on Oct. 22.
