Newly unsealed documents linked to the convicted sex offender have renewed scrutiny of the billionaire's personal life and health-related dealings

Bill Gates has apologized for his ties to the late convicted sex offender Jeffrey Epstein, saying he was "foolish" to spend time with him.

In an interview with 9 News Australia released on Wednesday, the billionaire Microsoft co-founder denied allegations raised in newly unsealed US Department of Justice records concerning his dealings with Epstein.

The DOJ published the final tranche of documents related to Epstein, including his personal emails, last week. Some alleged that Gates had extramarital "sex with Russian girls" arranged via Epstein's trafficking network and sought medication to treat a sexually transmitted infection afterward.

Some documents suggest Gates may have leveraged Epstein's network for health-related influence, with DOJ files citing meetings in which healthcare issues were discussed.

In the interview, Gates insisted he only had "a number of dinners" with Epstein focused on fundraising for global health initiatives linked to the Bill & Melinda Gates Foundation.

"The focus was always - he knew a lot of very rich people and he was saying he could get them to give money to global health," Gates said, claiming the talks led to nothing. "In retrospect, that was a dead end... I was foolish to spend time with him."

Gates denied visiting Epstein's private island or having any connections with women through Epstein's network.

"It had nothing to do with that kind of behavior," he said, dismissing the STD-related allegations as false. "Every minute I spent with him, I regret and I apologize that I did that."

Gates did not say what healthcare-related issues he discussed with Epstein.

Melinda Gates, who divorced Bill Gates in 2021, told NPR this week that the latest document release caused "unbelievable sadness," particularly for the young girls abused by Epstein. She previously said her former husband's association with Epstein was among the factors that led to divorce.

Gates was not the only high-profile figure named in the latest release of Epstein-related documents, which also reference US President Donald Trump, former US President Bill Clinton, and Tesla and SpaceX CEO Elon Musk, among others. All have denied having deep ties to Epstein.

Clinton, who has acknowledged flying on Epstein's private jet in the early 2000s but denied wrongdoing, agreed this week to testify before the House Oversight Committee alongside his wife, former US Secretary of State Hillary Clinton, as part of its investigation into Epstein.
