Geoffrey Berman, United States Attorney for the Southern District of New York, points to a photograph of Jeffrey Epstein as he announces the financier's charges of sex trafficking of minors and conspiracy to commit sex trafficking of minors, in New York, U.S., July 8, 2019.

Wealthy financier and accused child sex abuser Jeffrey Epstein had a revolving cast of characters take turns visiting him in a Palm Beach County, Florida, jail while serving a 13-month criminal sentence in 2008 and 2009, according to visitor logs reviewed by CNBC on Friday.

Those visitors included Epstein's appeals attorney Alan Dershowitz, who showed up on New Year's Day 2009, as well as Arnold Paul Prosperi, a college friend of former President Bill Clinton, documents show. Other visitors were two woman who have been alleged to have been co-conspirators of Epstein.

Epstein, also a former friend of President Donald Trump's, pleaded guilty in 2008 to a Florida state charge of procuring an underage prostitute.

He now is charged by federal prosecutors in New York with sexually abusing dozens of underage girls from 2002 through 2005 at his Manhattan townhouse and Palm Beach mansion.

Among his most frequent visitors in jail was Prosperi, who had become friends with Clinton when they attended Georgetown University together, where he ran Clinton's campaign for student body president.

Records show that Prosperi visited Epstein at least 20 times.

An attorney who later raised funds for Clinton, Prosperi had his own criminal sentence for filing false tax returns commuted to house arrest on Clinton's last day office in the White House in 2001.

A 1995 newspaper clipping uncovered by Snopes.com describes a dinner hosted by Revlon chief Ron Perelman and his wife, with guests including Clinton, who was president at the time, Prosperi and Epstein.

Other guests at that dinner included actor Don Johnson, singer Jimmy Buffett and Don Fowler, the then-co-chairman of the Democratic National Committee.

Clinton's spokesman has said that he cut ties with Epstein over a decade ago, and has no knowledge of Epstein's alleged crimes. On Friday, a representative for Clinton did not return CNBC's request for comment.

Dershowitz spent much of the morning on January 1, 2009, with Epstein, according to records. In a statement to CNBC, Dershowitz said, "I always visit clients in prison. We discuss legal issues. It was not a personal visit. It was professional."

Later that same holiday, Prosperi came by to see Epstein, as did Joseph Pagano, who has the same name as a venture capitalist previously reported to be a friend of Epstein. CNBC was unable to reach Pagano.

Other notable visitors were two of Epstein's alleged co-conspirators, Nadia Marcinkova and Sarah Kellen.

Combined, the two made over 70 visits to the Palm Beach County Jail, records show.

Kellen, according to a court document obtained by The Daily Beast, was one of Epstein's closest aides in the 2000s. She now goes by the name Sarah Kensington and is married to NASCAR driver Brian Vickers. Marcinkova is now a certified FAA pilot and a flight instructor.

Neither Kellen nor Marcinkova has been criminally charged. A non-prosecution agreement that Epstein signed with federal prosecutors in Miami in 2007, explicitly said that his alleged co-conspirators would not be criminally charged.
