At 8 p.m., the House Select Committee investigating the Jan. 6 attack plans to start unveiling the most complete and visceral dissection to date of the mob of Donald Trump supporters who stormed the U.S. Capitol in an attempt to overthrow the results of a democratic election.

Drawing on months of interviews and thousands of documents, the committee has thus far kept most of its findings close to its vest — so we expect a lot of new information and some of the most terrifying video from that day that hasn’t been shown to the public yet.

As one committee aide told reporters in a background call on Wednesday, they see their job as showing “that the violence of Jan. 6 was the result of a coordinated, multistep effort to overturn the results of the 2020 election and stop the transfer of power from Donald Trump to Joe Biden.”
