Louis C.K. has confirmed the stories are true.
The comedian made headlines after five women came forward to allege he masturbated in front of them without their consent.
The New York Times broke the story:
[…] after years of unsubstantiated rumors about Louis C.K. masturbating in front of associates, women are coming forward to describe what they experienced. Even amid the current burst of sexual misconduct accusations against powerful men, the stories about Louis C.K. stand out because he has so few equals in comedy. In the years since the incidents the women describe, he has sold out Madison Square Garden eight times, created an Emmy-winning TV series, and accumulated the clout of a tastemaker and auteur, with the help of a manager who represents some of the biggest names in comedy. And Louis C.K. built a reputation as the unlikely conscience of the comedy scene, by making audiences laugh about hypocrisy — especially male hypocrisy.
After the story broke, the fallout was immediate, and companies began to cut ties with the comic.
