Ashton Kutcher almost breaks into tears as he explains his real "day job"

Actor Ashton Kutcher wants to fight human trafficking, and he gave an emotional plea about what his "day job" really entails at his anti-trafficking foundation.

The celebrity and father-of-two gave details at a U.S. Senate hearing about the way internet trolls tell him to not comment on politics, and to "stick to my day job."

"So I'd like to talk about my day job," Ashton said. "My day job is as the chairman and co-founder of Thorn. We build software to fight human trafficking and the sexual exploitation of children.

"My other day job is that of a father of two: a 2-month-old and a 2-year-old, and as part of that job that I take very seriously, I believe it is my effort to defend their right to pursue happiness, and to ensure a society and government that defends it as well."

He then gave an account of some very serious and disturbing incidents of child sexual slavery he's encountered, almost breaking into tears at the thought of children the same age as his own in dangerous and awful environments.

The video of Ashton Kutcher's day job speech has already received more than 5 million views across Facebook and YouTube. Watch part of it in the video above.
