March For Our Lives co-founder Cameron Kasky told Fox News radio on Wednesday that he has left the organization that he helped create and that he has regrets about some of the things that he has said since he entered the public spotlight.

Kasky told Fox News Radio's Guy Benson and Marie Harf: "I'm very regretful of a lot of the mistakes that I've made along the way."

"One of the things I never really did was watch myself," Kasky said. "If I was on a screen I kind of tried to run away from it. I'm not entirely sure why. But, looking back on that it's like you said, you touched off on this very well in the intro, I'm not going to kick myself for it because I'm 17. Despite the fact that I thought I did at the time, I don't know everything."
