I'm not sure how the Senate demanding anything is a good thing.
My thoughts run along the lines of demanding the records so they're unavailable for FOIA, or the like, because of an "ongoing investigation", "national security", etc., etc. Bullshitters gonna' bullshit.
IOW, they have to guard against justices (Roberts, cough, cough) being Fauci'd.
Could be they see the writing on the wall with Fauci and are going to have to resort to a Bidan railroad job to keep Fauci on the reservation and to keep him from squealing to save his ass.. Bad optics, but fuck the public when it's down to brass tacks time. Priorities, and all. Can't have a twofer with, say, Roberts, on top of that.
TL;DR: I don't trust a fucking thing these critters do. It's a trap.
