Impeachment investigators released interview transcripts on Friday for two major witnesses: Lt. Col. Alexander S. Vindman, the top Ukraine expert on the National Security Council, and Fiona Hill, President Trump’s former adviser on Russia and Europe.

Tucked into Ms. Hill’s testimony is a cinematic scene at the White House. She describes how she and Mr. Bolton tried to foil attempts by Gordon D. Sondland, the ambassador to the European Union, to pressure Ukraine into an investigation, racing through the West Wing to stop him from promising a presidential meeting. (The scene can be found on pages 66 to 71.)

Below are quotations from Ms. Hill’s transcript, with annotations from reporters and editors in our Washington bureau.

The setting: The White House, July 10; a meeting in Mr. Bolton’s office, near the Oval Office, between U.S. and Ukrainian officials to discuss national security, energy policy and the possibility of a White House visit for Ukraine’s new president.
