Ashton Kutcher won the Senate Foreign Relations Committee about ending sex slavery on Wednesday in perhaps one of the most moving speeches given that day.

“This is about the time, when I talk about politics, that the Internet trolls tell me to stick to my day job,” he said. “I’d like to talk about my day job. My day job is the chairman and the co-founder of Thorn. We built software to fight human trafficking and the sexual exploitation of children. My other day job is that of the father of two, a 2-month old and 2-year-old.”

Ashton talked about working with the FBI to raid places in India, Mexico, Russia, and even in New York and New Jersey: “I’ve seen things that no person should ever see,” he said. “I’ve seen video content of a child that is the same age as mine being raped by an American man that was a sex tourist in Cambodia. This child was so conditioned by her environment that she thought she was engaging in play…

“I’ve been on the other end of a phone call from my team asking for my help because we had received a call from the Department of Homeland Security, telling us that a 7-year-old girl was being sexually abused and that content was being spread on the Dark Web,” he continued. “They’d watched her for three yearsand they could not find the perpetrator, [and were] asking us for help. We were the last line of defense. An actor and his foundation were the last line of defense.

“I had to say no and it devastated me, it haunted me. For the next three months I had to go to sleep every night and think about that little girl that was being abused and the fact that if I built the right thing, we could have saved her. Now, if I got that phone call, the answer would be yes.”
