PARK CITY, Utah Nearly 22 years ago, Hillary Rodham Clinton was blindsided when her husband, then President Bill Clinton , came into their room, sat down on the bed and confessed to having an affair with a 20-something White House intern named Monica Lewinsky a scandal that had been splashed across headlines for seven and a half months.

I told her exactly what happened, when it happened, Bill Clinton says in the new Hulu four-part docuseries Hillary, which debuted at the Sundance Film Festival on Saturday and will be released on the site on March 6. I said, I have no defenses. This is inexcusable, what I did.

This is by far the most open Bill and Hillary Clinton have been about the situation that nearly ended their 22-year marriage in August 1998. Hillary director Nanette Burstein told The Hollywood Reporter that the couple was willing to recount the experience in separate interviews, due to its significance in Hillarys personal life, which the docuseries explores in-depth.

The reason why the Monica story was important to me was not just for the sake of it being salaciously interesting to people, the filmmaker said, but because [Hillarys] always been judged by it.
