I didn't follow the story at the time but I was under the impression that the Comet Pizza theory and the Epstein theory were the same theory. If the Comet Pizza / Hillary Clinton / Satanic baby eating stories did not mention Jeffrey Epstein than I'm sorry that I got them confused. I'd have to research deeper to sort that out; memory works in weird ways as it's partially reconstructed from fragments.
Epstein was an already known sex offender and had previously done time for it.
