Bill Gates is expected to face uncomfortable questions on Wednesday having little to do with helping found Microsoft or his global health philanthropy, as members of a U.S. congressional committee are likely to probe his relationship with the late sex offender Jeffrey Epstein.

Gates will sit for a closed-door interview before the House Oversight Committee about his relationship with convicted sex offender Jeffrey Epstein.

The billionaire met with Epstein multiple times between 2011 and 2014.
