The former "Daily Show" host said Tuesday on NBC's "Today" show that inappropriate behavior is "endemic" in the comedy community and that it is an especially harsh environment for women.
As the interview came to a close, Lauer asked if Stewart had talked to C.K. since last week's New York Times story broke. Stewart, who was joined by the benefit's creator Michelle Smigel, had been quiet about the Louis scandal, but many were waiting to a response from him.
Stewart says he has not spoken with C.K. since the The New York Times published a report on November 9 in which five women accused C.K. of sexual misconduct, including asking all of the women if he could masturbate in front of them.
Still, Stewart said he hopes that with emerging allegations against C.K. "You give your friends the benefit of the doubt". You always find yourself back to a moment of, did I miss something?
Stewart, 54, also said he was angry with himself for brushing off and defending rumors about C.K.'s bad behavior when they were brought to his attention directly. Could I have done more?' And in this situation, I think we all could have.
Stewart went on to say that "comedy on its best day is not a great environment for women" and even though it's gotten better in recent years, it is still a tough field for women. He laughed off the question and answered, "So the Internet said Louis harassed women?" And I think if you talk to women, they are in a very hard position. "No, I didn't see the tweets. I'm not that connected to that world". I don't know what you're talking about.... "I hadn't heard, at that point, at any of it", Stewart remembered.
Stewart addressed the clip in his Today interview.
"My first response was, 'What?' And then, joke, joke, and as he kept going, I was like, 'Look, I know this is very serious, but I know Louis, he's always been a gentleman to me, ' which, again, it speaks to the blindness that I think a man has, which is, like, 'hey, he's a good guy, what are you talking about?'" Stewart said. The comic was scheduled to appear on Night of Too Many Stars opposite Stewart, but HBO cut the comedian's scheduled appearance on Thursday.
