Kent, the deputy assistant secretary of State for European and Eurasian Affairs, oversees administrative policy in a bloc of Eastern European countries, including Ukraine, which has emerged as the focal point of the Democrats' growing investigation.

Amid that transition, impeachment investigators on Thursday heard from what could be their last witness to be interviewed privately: Jennifer Williams, a career foreign service officer and top national security adviser to Vice President Pence, huddled behind closed doors for roughly five hours.
