I don't suspect there will be any Great New Revelations during the course of the day, but then no one has any idea how taciturn Mueller will get, and how he'll respond if challenged by Republicans. My guess is "taciturn" for most of the day, but the reality is that there don't need to be any "Great New Revelations." All it really needs is to get out to the public what's actually already in the Mueller Report, which nearly all of America has not read, which most people probably know next to nothing about -- including all those masses of Republicans who truly believe Trump when he says the Report completely vindicated him with no collusion, no obstruction -- yet the Report says completely otherwise.
In place of our interruption, we have a new song parody from Randy Rainbow, "Suckers," based on the song "Sucker" from the Jonas Brothers. There's a segment about 3-and-a-half minutes in that's especially wonderfully done, and I'll leave it at that.
