How Bloomberg News Vetted the Epstein Emails

Bloomberg News used multiple methods to test the authenticity of thousands of emails sent to and from the disgraced financier Jeffrey Epstein, including cryptographic analysis, metadata analysis and corroboration with external sources.

We examined the emails themselves as well as enclosures to the emails. Four independent experts reviewed our methods and said they aligned with best practices. In summary, these examinations strongly authenticated a portion of the emails; corroborated sources of important enclosures; and found no meaningful evidence of fakery. We did find evidence that some emails had been deleted.
