What’s already been released?

A 100-page introduction to the full report is already available on the Jan. 6 Committee site in both PDF form and embedded on the page itself.
According to a report from Politico citing unnamed sources familiar with what’s happening, the report will be organized into eight chapters and four appendices. The first two appendices will cover the Capitol police’s response to the riot and examine dispatchers’ slow response to calls from reinforcements from those on the ground. The third appendix will reportedly analyze who was funding the Stop the Steal rally which preceded the storming of the Capitol. A fourth appendix will look into foreign governments’ reaction to the Jan. 6 insurrection and the ways in which they capitalized on the news.
