The former late-night host David Letterman said he was surprised that CBS didn’t hire a female successor at “The Late Show,” and is now calling for television networks to employ more women.

Letterman made remarks during an interview with NBC News’ Tom Brokaw that will be airing on Sunday, June 12th. He stated: “I don’t know why they didn’t give my show to a women.”

While Letterman said he “couldn’t care less about late-night television,” there were some changes he would have liked to see. Letterman was conflicted when he saw Colbert take his desk after his retirement.

“When he went on the air, an energy left me and I felt like, ‘You know, that’s not my problem anymore.’ I devoted so much time, to the damage of other aspects of my life. The concentrated, fixated, focusing on that…it’s good now to not have that.”

Letterman, whose show was notoriously known for not being full of women, now believes there should be the change.

“I’m happy for the guys—men and women—there should be more women. And I don’t know why they didn’t give my show to a woman,” Letterman continued. “That would have been fine. You know, I’m happy for their success. And they’re doing things I couldn’t do. So that’s great.”
