WATCH LIVE: Impeachment Hearings Resume With White House, State Department Witnesses

7 hours ago

House Democrats have begun week two of their open impeachment hearings on Tuesday with witnesses who listened firsthand when President Trump spoke with President Volodymyr Zelenskiy on July 25 — a key moment in the Ukraine affair.

And members of Congress also said they've added a new witness to those slated to appear this week: David Holmes, the diplomatic aide posted to Ukraine who appeared for a closed-door deposition last week, now is scheduled to appear in an open hearing on Thursday morning.

The hearing opened with Lt. Col. Alexander Vindman, an Army foreign area officer who serves on the National Security Council, and Jennifer Williams, a foreign service officer detailed to the staff of Vice President Mike Pence.

Vindman and Williams were among the White House staffers who listened in on the phone call.
