My sense/hope is that there are factions in the intelligence community that have backups upon backups. That it would be impossible to erase every single copy of every single document in across multiple organizations, public and private. For example, All the Epstein financial records are also sitting in some bank database somewhere. Maybe it's on tape and they gotta run an archival search, but there is a trail.
The victims are real. They just put out a big ad in the last few days.
That said, Trump is strong enough and his opposition is weak enough that it won't matter.
