The former talk show host said her father, Edward Joseph, began sexually abusing her at a young age. Her mother died when she was 10.

“It started very young,” O’Donnell said. “And then when my mother died, it sort of ended in a weird way, because then he was with these five children to take care of. On the whole, it’s not something I like to talk about. Of course, it changes everyone. Any child who is put in that position, especially by someone in the family, you feel completely powerless and stuck, because the person you would tell is the person doing it.”
