Billionaire Bill Gates testified in a closed-door hearing before the House Oversight Committee on Wednesday about his relationship with Jeffrey Epstein.

Gates, the co-founder of Microsoft and one of the world’s most prominent philanthropists, told members he had no knowledge of Epstein’s crimes and that Epstein attempted to use information about his personal life to pressure him.

During his opening statement, Gates said he exercised poor judgement in meeting Epstein and was “one of many people who regret ever knowing him”.

The BBC’s Gary O’Donoghue breaks down the relationship between Gates and Epstein, and how lawmakers reacted to his testimony.
