What is the goal of Congress getting the unredacted report?

I mean, I know transparency is good and I want them to get it. But what do we expect to come of it? If they get it but still can't share it, I feel like any information learned from it will still matter exactly zero to anyone in the GOP voter base.

So what do we hope comes of it? Is it so that they can potentially see if further investigations need to be opened after seeing what has been left out? Or is it literally just for transparency's sake, with no goals or expectations of any kind?
