Bill Gates is going to Congress in June, and he is bringing with him a decade’s worth of questions that the world’s richest philanthropist has spent years trying to answer on his own terms.

The House Oversight Committee confirmed Tuesday that the Microsoft co-founder will testify on June 10 about his relationship with Jeffrey Epstein, the convicted sex offender whose network of powerful connections has been pulling high-profile figures into congressional scrutiny at a steady pace since the Trump administration signed legislation last November requiring the Justice Department to release all investigative files related to Epstein’s crimes.

Those files — more than three million documents disclosed earlier this year, with millions more still withheld — contained details of Gates’ communications and interactions with Epstein, putting the billionaire philanthropist in a position he has been navigating carefully ever since. A Gates spokesperson said Tuesday he was “looking forward to answering all the committee’s questions to support their important work.” The phrasing is the cooperative language of a man who knows that resistance to a congressional summons carries its own implications.

Gates has not been accused of wrongdoing by any of Epstein’s victims. His inclusion in the investigative record does not constitute an allegation of criminal conduct. What it does constitute is an uncomfortable public accounting of a relationship he has repeatedly said he regrets.

He has been working through that accounting incrementally. Earlier this year, in an interview with Australia’s 9News, he described his interactions with Epstein as limited to dinners, said he never visited Epstein’s island, and offered a statement that has since become his most quoted on the subject: “Every minute I spent with him I regret and I apologise that I did that.”

He also addressed staff at the Gates Foundation directly, the Wall Street Journal reported, apologising and disclosing that he had two affairs with Russian women which Epstein subsequently discovered. On the core question of criminal activity, he told his staff: “I did nothing illicit. I saw nothing illicit.” A Gates spokesperson later confirmed to the BBC that the philanthropist had never attended parties with Epstein and had no involvement in the illegal activities associated with him, describing the decision to meet Epstein at all as “a serious error in judgment” that he unequivocally denies translated into any improper conduct.

June 10 will be the first time he makes that case under oath before Congress.

The committee has been building its witness list through a series of high-profile appearances. Bill and Hillary Clinton testified in February. Commerce Secretary Howard Lutnick and recently fired Attorney General Pam Bondi are expected in the coming weeks. The procession of names — former presidents, cabinet secretaries, the world’s most recognisable philanthropist — reflects both the breadth of Epstein’s connections during his lifetime and the political weight Congress is placing on a reckoning that his victims have been demanding for years.

Gates arrives at that reckoning having tried to get ahead of it through public statements, foundation meetings and media interviews. Whether the committee finds those prior accountings sufficient, or uses June 10 to probe further into a relationship whose full contours the documents have not yet fully illuminated, remains to be seen.

The Justice Department has released millions of documents. Millions more have not been released. That gap is part of what the committee is working toward closing — and part of why the hearings keep producing new names.
