Actor Ashton Kutcher testified before Congress on Wednesday, highlighting his efforts to help end human trafficking.

But the Hollywood star also had a few moments of levity at the hearing, at one point blowing a kiss to Sen.

“Ashton, you were better looking in the movies,” McCain joked at one point, leading Kutcher to respond with an air kiss.

“He flew all night. He’s working right now on a film, so he caught a red-eye in after having dinner with his wife, said Corker.

“Very smart man, on Valentine’s Day,” he joked.

But the hearing was a serious affair, as the 39-year old actor dicussed his work as co-founder of Thorn, an organization that works with law enforcement to better use technology to fight human trafficking.

In his remarks, Kutcher also addressed critics who question why the celebrity is speaking about such matters.

“This is the part where I start talking about politics and the internet trolls tell me to stick to my day job, so I’d like to talk about my day job,” Kutcher said. “My day job as the chairman and co-founder of Thorn. We build software to fight human trafficking and sexual exploitation of children, and that’s our core mission.”

Kutcher also talked about his experiences as a father of two children, a two-month-old and a two-year-old, which he said motivates him to help others.

He said he had seen the problem of human trafficking first hand, accompanying the FBI on raids and had “seen things no person should ever see.” 

His voice trembled when he spoke of viewing a video of a child being raped by an adult male.

“The right to pursue happiness for so many is stripped away — it’s raped, it’s abused, it’s taken by force, fraud, or coercion. It is sold for the momentary happiness of another,” he told lawmakers.
