So, produce the tape. Don’t talk about it, drop it on the internet.
And make out your will.
If there was a tape of this, I wonder who made it. It would be easy enough to release, although there may be an NDA involved - in which case it would have to be publicly disclosed through somebody else like law enforcement or Congress. If the tape exists and can be confirmed as authentic the best way may be to charge E Jean Carroll with perjury and the DNC with subornation of perjury.
