Oh I have zero doubt it will still get out. I have even less doubt that I would contain anything we didn't already know.I think it's inevitable that the report will be leaked. It's not as if it's a Top Secret document or anything. (As if that would matter.)
But it not being "officially" released is exactly the kind of "out" those "I'm totally not a Trumper, don't you dare call me a Trumper, now if you'll excuse me my mouth has been on Trump's you know what for 10 whole seconds, let me get back to that" Trumpers in Congress will use to pretend like it doesn't count so they can do the whole "Well I don't want to confirm Gaetz but there's nothing official so my hands are tied LOL watcha gonna do" routine.
