I have no problem waiting and seeing, but if such a tape exists and is in the possession of prosecutors, do you think they're going to put it out on social media? Why would they release it now? Seems well within the realm of the possible that they might have a recording.
I've read other reports (to be fair, unverified at this point) that the DOJ has flipped some among Trump's inner circle -- testimony/cooperation in exchange for leniency or possibly even immunity.
I think we'll soon see, one way or the other.
