Louis C.K. acknowledged the accusations were true and apologized. "These stories are true. At the time, I said to myself that what I did was okay because I never showed a woman my dick without asking first, which is also true," he said in a statement obtained by CNN at the time. "But what I learned later in life, too late, is that when you have power over another person, asking them to look at your dick isn't a question. It's a predicament for them. The power I had over these women is that they admired me. And I wielded that power irresponsibly."Related: FX severs ties with Louis CKLouis C.K. went on to say that he is "remorseful" and has "tried to learn" from his irresponsible behavior.FX cut ties with him shortly after.
