House Democrats on Thursday released the transcript of testimony from George Kent, a senior State Department diplomat who is expected to testify publicly next week.

Kent notably voiced concern over Rudy Giuliani's contacts with Ukraine as early as March of this year, prompting a supervisor to advise him to 'lay low' according to The Hill.

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. The verbatim transcript is the sixth to be released by the Democrats this week, as they wind down the closed-door deposition stage of their impeachment investigation and transition to a public-hearing phase, beginning next week. 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 advisor to Vice President Mike Pence, huddled behind closed doors for roughly five hours. -The Hill
