Victims of convicted sex offender Jeffrey Epstein on Saturday expressed anger after a long-awaited cache of records from cases against him were released with many pages blacked-out and photos censored.

"Just put out the files and stop redacting names that don't need to be redacted," Marina Lacerda, an accuser of Epstein, told CBS.

"Are we protecting the survivors or are we protecting these elite men? The whole process of being transparent was to only redact the survivors and the victims' names."

Another Epstein survivor, Jess Michaels, said she spent hours combing the documents to find her victim's statement and communication from when she had called an FBI tip line.

"I can't find any of those," she told CNN. "Is this the best that the government can do? Even an act of Congress isn't getting us justice."

Republican congressman Thomas Massie, who has long pushed for the release, said it "grossly fails to comply with both the spirit and the letter of the law."

That law required the government's entire case file to be posted publicly by Friday, constrained only by legal and victim privacy concerns.

Senate Minority Leader Chuck Schumer said Democrats would "pursue every option to make sure the truth comes out."

Deputy Attorney General Todd Blanche acknowledged in a letter to Congress that the Friday release was incomplete, and that the Justice Department would complete production of files in the coming weeks. (AFP)
