Steps away from the Capitol, victims of Jeffrey Epstein, the disgraced financier and sex offender, on Wednesday demanded that all people who received sexual favors through Mr. Epstein be identified.

They also demanded that Ghislaine Maxwell, the longtime associate of Mr. Epstein who is serving 20 years for sex trafficking, serve her full sentence without special treatment. Ms. Maxwell was moved to a minimum security prison in Texas after President Trump’s lawyers and a senior Justice Department official interviewed her in July.

During the interview, Ms. Maxwell, who is seeking a presidential pardon or reduction of her sentence, downplayed Mr. Trump’s long friendship with Mr. Epstein and praised the president.

The victims’ demands arrive as members of Congress from both parties are pushing for a bill that would demand the administration release all of its investigative material on Mr. Epstein.

“We are not asking for pity, we are demanding accountability,” said Lisa Phillips, one of the victims who spoke on Wednesday. “Congress must choose: Will you continue to protect predators, or will you finally protect survivors? Transparency is justice.”

The Epstein files have become a burden for Mr. Trump, who has for months urged his base not to focus on them. At the White House on Wednesday, Mr. Trump called the matter “a Democrat hoax.”
