The Jan. 6 hearings overlapped the next (Congressional) elections, they didn’t come before them.
(And, of course, the information was laid out structurally, but one might reasonably be concerned with potential insertion of bias by the people setting the structure and filtering the information–which I don’t particularly think was a problem in that case, but it certainly would be something to be reasonably concerned about—a problem that can be mitigated somewhat if one does not rely on that presentation as the sole source of information on the event.)
Actually I do more like quarter in review or year in review. For example, I know Obama and Bill Gates do yearly reviews on big things that happened.
For events like Jan 6, I tend to stay away from the coverage and what for the official hearing where it's laid out structurally.
As long as the info comes before the next election, it's fast enough.
