Dr. Melanie S. Walker started working for Gates's foundation in 2006 after striking up a relationship with Microsoft exec Steven Sinofsky.

It begins, as so many Jeffrey Epstein stories do, in a room where power recognised power. In this case, the room was reportedly the Plaza Hotel in New York in the early 1990s.

Gates struck up a friendship with Epstein in 2011 after the financier promised he could help raise billions of dollars for global public health initiatives.

Bill Gates said that he ended the relationship in 2014 after concluding Jeffrey Epstein could not deliver on those promises.

Bill Gates testified about his past association with Jeffrey Epstein, acknowledging infidelity in his marriage.

The Microsoft co-founder told Congress that the sex offender discovered he had had affairs during his marriage and tried to use that information against him.
