The United States Congress has approved a bill to release government documents related to sex offender Jeffrey Epstein, clearing the way for making the files public.

The House of Representatives adopted the measure in a 427-1 vote on Tuesday, sending it to the Senate, which swiftly agreed to pass it by unanimous consent even before it was formally transmitted to the chamber.

Once the bill is formally approved, it will go to the desk of President Donald Trump, who said he would sign it into law.

The case of Epstein – a financier who sexually abused girls and young women for years – has sparked intrigue in the US for years, given his connections to powerful people in the media, politics and academia, including ties to Trump.

Trump initially opposed releasing the files, calling the controversy around the late sex offender a “hoax” before reversing course this month.

The president and his Department of Justice do not need to wait for Congress to pass the legislation to release the files. They have the authority to make them public.

Before the vote on Tuesday, members of Congress who have been leading the bill – Democrat Ro Khanna and Republicans Thomas Massie and Marjorie Taylor Greene – spoke alongside survivors of Epstein’s abuse outside the US Capitol.

“We fought the president, the attorney general, the FBI director, the speaker of the House and the vice president to get this win. They’re on our side today, so let’s give them some credit as well,” Massie told reporters.

Jena-Lisa Jones, one of the survivors, held up a photo of herself when she was 14 – the age when she met Epstein.

“I was a child. I was in ninth grade. I was hopeful for life and what the future had held for me. He stole a lot from me,” she said.

Epstein first pleaded guilty to charges of solicitation of prostitution with a minor in 2008. He served 13 months in a minimum-security prison and was allowed to leave for 12 hours a day to work. Critics said the punishment did not match the severity of the offence.

After the Miami Herald investigated the prosecution against Epstein, federal authorities reopened the case against him, arrested him and charged him with sex trafficking of minors in 2019.

Two months later, he was found dead in his jail cell in New York City. His death was ruled a suicide.

Epstein’s associates over the years included former Israeli Prime Minister Ehud Barak, the United Kingdom’s Prince Andrew and former US President Bill Clinton.

Even after his first conviction, Epstein continued to have close personal relationships with influential figures, including former Harvard University President Larry Summers, who recently apologised for maintaining ties to the sex offender.

On Tuesday, Trump lashed out at an ABC News reporter who quizzed him about why he would not release the files on his own, stressing that Epstein was a major donor for Democratic politicians.

“You just keep going on the Epstein files. And what the Epstein is is a Democrat hoax,” the US president said.

Earlier in the day when asked why Trump would not make the documents public, Massie said Epstein’s connections were above partisan politics.

“I believe he’s trying to protect friends and donors. And by the way, these aren’t necessarily Republicans,” Massie said. “Once you get to a billion dollars, you see, you transcend parties.”
