The founder of Microsoft, Bill Gates, will testify this Wednesday before the United States House of Representatives as part of the investigation that Congress maintains into the case of sex offender Jeffrey Epstein.

The appearance, which will be held behind closed doors before the House Oversight Committee, seeks to clarify the nature of the relationship that the businessman had with Epstein during the years prior to the financier's death.

Gates' name appeared among more than three million pages of documents, photographs and videos released by the Justice Department last January, reviving interest in his contacts with Epstein.

The documents include references to alleged emails from 2013 in which Epstein alleged that Gates was having an extramarital affair and was seeking medication to treat a sexually transmitted disease. However, the businessman has categorically denied all accusations.

“I regret every minute I spent with him,” Gates

“That email was never sent, it is false,” Gates said when referring to the documents. In addition, he maintained that he does not know Epstein's intentions when writing those messages.

The tycoon has also insisted that he never committed any irregularities and has publicly expressed his regret for having maintained contact with the financier.

“I regret every minute I spent with him,” he previously declared, while calling it “senseless” to have met with Epstein on several occasions.

Gates has acknowledged that he met Epstein in 2011 and that the two shared some dinners, although he denied having visited the financier's private island in the Virgin Islands.

The congressional investigation has also included testimonies from other high-profile figures, including former President Bill Clinton and former Secretary of State Hillary Clinton, who already appeared before the same committee as part of the investigations related to the Epstein case.
