Listening to TRIP US this morning, the existence of the “Birthday Book” has been confirmed with it previously being mentioned in court proceedings and it’s believed to be in the possession of Epstein’s lawyers.
Like Mooch said, there’s no way WSJ would have published the story without verifying that any such letter actually existed in the first place.
