Survivors joined Schumer at Wednesday's press conference, including Laura Mullen, who said she was molested by her own grandfather as a child.
"Even at church. It's happened at church in the basement, so like, it didn't matter where. On the way to school, driving to school," she said. "I was a child, a child who didn't know any better."
She remembered the fear and the shame surrounding her abuse, and said it took years before she was able to speak about it.
"I was always hiding this dark secret," Mullen said.
