The US justice department has released an initial tranche of documents related to Jeffrey Epstein.

The documents, which include photos, videos and investigative documents, were highly anticipated after Congress passed a law mandating the files be released in their entirety by Friday.

However, Democrats and some Republicans accused the Department of Justice (DOJ) of violating its legal obligations after it said it would not be able to release all the documents by the deadline. Many details in the thousands of files have also been heavily redacted.

A number of famous faces are included in the first batch of files, including former US President Bill Clinton, Andrew Mountbatten-Windsor, and musicians Mick Jagger and Michael Jackson.

Being named or pictured in the files is not an indication of wrongdoing. Many of those identified in the files or in previous releases related to Epstein have denied any wrongdoing.

Several of the images released include former US President Bill Clinton. One picture shows him swimming in a pool, and another shows him lying on his back with his hands behind his head in what appears to be a hot tub.

Clinton was photographed with Epstein several times over the 1990s and early 2000s, before the disgraced financier was first arrested. He has never been accused of wrongdoing by survivors of Epstein's abuse, and has denied knowledge of his sex offending.

Among the documents released on Friday are many that are redacted, including police statements, investigative reports and photos. More than 100 pages in one file related to a grand jury investigation are entirely blacked out. The timing of when additional materials will be released is unclear, prompting frustration from legislators.

Deputy Attorney General Todd Blanche stated that there are still several hundred thousand pages to be reviewed and made public. As the investigation continues, the implications of these disclosures on the reputations of those named remain to be seen.
