I have the impression she either realized or was told/shown how the Trump admin plans to stay in power forever, plus all the economic lies, and this disheartened her to a great extent.
On top of that the pushback from trump, and most likely her receiving covert threats to stay out of the way, is what also made her come to this decision.
I am curious if her stepping down will stick in the long run.
Most likely there are a few other "originals" out there that keep all involved parties in check.
Epstein had files stashed on the island but also his Manhattan office (which got stolen after the fbi opened the safe but did not remove them), ghislaine is said to have files, and probably one copy is in the hands of putin, epstein was in Moscow....
So if the trump admin releases an overtly fake version that exonerates everyone "on his side" another party can release opposing documents.
This already somewhat happened last month, where the administration released redacted files and highly selected documents, where suddenly various publicly unknown epstein emails surfaced that pointed back to trump.
