Watch live: Kinzinger, surprise Jan. 6 committee hearing

The House committee that includes Illinois Rep. Adam Kinzinger investigating the Jan. 6 riot at the U.S. Capitol will hold another hearing on Thursday afternoon.

The committee will hear testimony Tuesday from Cassidy Hutchinson, a top aide in Donald Trump’s White House who is a vital witness in the sweeping investigation into the Jan. 6, 2021 attack, a person familiar with the matter told The Associated Press.

Hutchinson, a special assistant and aide to Trump’s chief of staff, Mark Meadows, has already provided a trove of information to the committee and its investigators and sat for multiple interviews behind closed doors.

In brief excerpts of testimony revealed in court filings, Hutchinson told the committee she was in the room for White House meetings where challenges to the election were debated and discussed, including with Republican lawmakers.

The House panel has not explained why it abruptly scheduled the 1 p.m. hearing as lawmakers were away from Washington on a two-week recess. The committee had said last week that there would be no more hearings until July.

Hutchinson previously told the committee that Meadows had been advised of intelligence reports showing the potential for violence on Jan. 6 and that several Republican lawmakers who had been involved in efforts to reject the electoral tally or submit “fake electors” had sought pardons to avoid potential criminal prosecution.
