After the House of Representatives voted on Tuesday to release the "files" of convicted former financier Jeffrey Epstein, the Senate also took a similar step.
Senate Minority Leader Chuck Schumer called for the bill to be passed, and no senator opposed it.
The bill now goes to US President Donald Trump for his signature.
Epstein's victims spoke at a press conference at the US Capitol ahead of Wednesday's vote.
Annie Farmer said they have suffered "institutional betrayal" for years.
Speaking alongside the survivors, Republican Congresswoman Marjorie Taylor Greene attacked her former ally Trump.
Taylor Greene, whom Trump has called a "traitor," said the Epstein case had "destroyed MAGA" (Trump's "Make America Great Again" movement).
Donald Trump called days ago for his party to vote for the release of the files.
Trump has previously said he cut ties with Epstein years ago. He has always denied any connection to Epstein's sex abuse and trafficking.
Epstein was a child sex offender. He was investigated in 2005 after a parent accused him of sexually abusing a 14-year-old girl as a teacher. He was initially convicted in 2008 and released after 13 months. He was arrested again in 2019. During his trial, he was found dead in his cell on August 10, 2019.
