The Justice Department released thousands of new records on convicted sex offender Jeffrey Epstein on Friday, but at least 550 pages in the documents are fully redacted, CBS News has found.

The newly released files included photos of several prominent people in Epstein’s orbit, images from his homes and investigative records that detail disturbing allegations against the late sex offender. But the heavy redactions in many of the records have drawn criticism from Democrats and some Republicans, as the department defends its handling of the files.

One series of three consecutive documents — totaling 255 pages — is entirely redacted, with each page covered by a black box. A fourth 119-page document labeled “Grand Jury-NY” is also entirely redacted. It’s unclear what proceedings it stemmed from, but the document listed immediately before it is a transcript in which a prosecutor asks a grand jury in 2020 to consider evidence for a superseding indictment of Epstein’s convicted co-conspirator, Ghislaine Maxwell.
