A new investigation examining emails sent between federal investigators and prosecutors has raised fresh doubts over the Department of Justice’s claim that it has released the full cache of Jeffrey Epstein files, suggesting the material made public amounts to just 2% of the data gathered by federal agents.

Channel 4 News reported that internal emails seen by its journalists show federal investigators expected to process between 20 and 40 terabytes of data seized from Epstein’s properties, including his Florida mansion, New York townhouse, and private island.

The broadcaster added that emails between investigators discussed the data “totaling” up to 50 terabytes from the “earliest stages” in June 2020.

In another internal email from 2025, the report continued, officials said that they were “looking at approximately 14.6 terabytes of archived data.”
