A US congressional panel has released a trove of documents related to the federal investigation into the late sex offender Jeffrey Epstein.

The House of Representatives Oversight Committee published 33,295 pages, including flight logs, jail surveillance video, court filings, audio recordings and emails.

But Republicans and Democrats alike said the files contained little new information and it is unclear if the justice department is withholding other Epstein records.

Pressure has been growing from President Donald Trump's own supporters for more transparency on the probe into the well-connected financier after the justice department said in July there was no incriminating Epstein client list.

Oversight Committee Chairman James Comer, a Republican, ordered the documents to be published online on Tuesday.

The Republican-led panel received the files after issuing a legal summons to the Department of Justice last month.

But Comer, a Kentucky congressman, acknowledged there was little fresh information. As far as I can see, there's nothing new in the documents, he told NBC News.

The videos released on Tuesday include footage from outside Epstein's New York jail cell on the night of his death, comprising 13 hours and 41 seconds of video from the evening of 9 August to the morning of 10 August 2019, when Epstein died. This is two hours more than previously released footage, yet still omits the so-called missing minute noted in prior investigations.

Democratic congresswoman Summer Lee stated that the only notable new disclosure was flight logs detailing Epstein's movements to and from his private island in the US Virgin Islands.

Despite the release, top Democrat Robert Garcia warned that 97% of the documents had been previously made public, emphasizing that there was no mention of a client list and limited transparency for victims.

Lawmakers are expected to hold a press conference on Capitol Hill, addressing the public's concerns over Epstein, whose past connections included influential figures like Trump and former President Bill Clinton.
