Investigation of the January 6th Insurrection

Jennifer Rubin, whom I regard as the most insightful of the Washington Post columnists, has adopted a policy of selectively answering questions submitted by readers. I asked her this one yesterday:

In the wake of Republicans blocking Congressional authorization of a commission to investigate the January 6th insurrection, what steps are being taken by appropriate Congressional committees to conduct their own investigations; to what degree will they be coordinated; will they possibly produce a report embracing their collective findings; to what degree will they be able bring out the key facts that Republicans are trying to keep hidden; and can this be accomplished sufficiently in advance of the 2022 elections?
