Watch live coverage of a public hearing from the House Select Committee investigating the Jan. 6, 2021, attack on the U.S. Capitol. Cassidy Hutchinson, a top aide to Mark Meadows when he was White House chief of staff in the Trump administration, is expected to testify.

This is the sixth in a series of public hearings. Afterward, the committee of seven Democrats and two Republicans will report its findings sometime before the midterm elections on Nov. 8. Trump and his Republican allies continue to call the probe a witch hunt focused on scoring political points.
