Former White House aide recounts play-by-play of the West Wing leading up to Jan. 6

Hutchinson depicted a West Wing where some staff were extremely concerned about violence erupting at the Capitol that day – and others, like Trump and Meadows, were not.

Throughout the hearing, Trump responded to her testimony, labeling it "fake" and calling Hutchinson someone he "hardly" knew and "bad news" in posts to the social media network Truth that he owns and controls.

The committee had announced the hearing on Monday with less than a day's notice "to present recently obtained evidence and receive witness testimony" after saying there would be no additional hearings until July. Given that urgency and the major pieces of information Hutchinson had already shared with the Democrat-led committee for its nearly 11-month investigation, expectations were set that her testimony, presented in person and in recordings from her four committee interviews, would be significant.
