US President Donald Trump says he has signed off on legislation to force the release of the "Epstein files" — the final step required to turn the bill into law.

It means the US Department of Justice now has a 30-day deadline to release all unclassified documents about its investigation into late sex offender Jeffrey Epstein.

The bill was approved by both houses of the US Congress on Tuesday, US time.

Just one member of Congress, Republican Clay Higgins, voted against it.

But some, including House Speaker Mike Johnson, raised concerns that the bill compelled the release of too much information and innocent people could be implicated.

He called on the Senate to amend the bill, but senators agreed to pass it by "unanimous consent", removing the opportunity to debate it or make changes.
