An Ivy Leaguer who ran an organization advocating for the end of sexual violence has been arrested in New York for trying to set up a sexual tryst with children as young as two.

Joel Davis was charged with attempting to sexually exploit a child, enticing a child to engage in sexual activity and possessing child pornography, The Washington Post reported.

What makes the case so egregious is that Davis, a 22-year-old Columbia University student, is the founding executive director of the international group Youth to End Sexual Violence, focused on child victims, the newspaper reported.

He has worked alongside actress Angelina Jolie and was reportedly nominated for a Nobel Peace Prize.

Davis was also a Hillary Clinton supporter:

‘Why not leave the country? Because despair is no answer. To combat authoritarianism, to call out lies, to struggle honorably and fiercely in the name of American ideals –that is what is left to do. That is all there is to do.’ #election2016 A post shared by Joel Davis (@supercoolkid212) on Nov 9, 2016 at 11:55am PST

And his liberal bona fides don’t stop there, as he served as a youth ambassador for the United Nations.

More from the Washington Post:

He was the founding executive director of the international organization Youth to End Sexual Violence. He served as a youth ambassador for the United Nations special representative on sexual violence in conflict. He was on the steering committee of the International Campaign to Stop Rape & Gender Violence in Conflict, a group of more than 5,000 human rights organizations and experts worldwide.

The Post reported that, according to a federal criminal complaint, Davis exchanged text messages with undercover FBI agents, trying to arrange meetings with a 9-year-old girl, an 8-year-old girl and a 2-year-old boy.

He allegedly sent sexually explicit photos and videos of children and infants, and was clear in his communications with the FBI agents that he wanted to engage in sex with children of any age

The complain also said Davis admitted to meeting a 13-year-old boy on the dating app Grindr, speaking with him on Snapchat. He engaged in sexual activity with the child in June at his Manhattan apartment.

U.S. Attorney Geoffrey S. Berman called Davis’s alleged actions “unfathomable.”

“Davis started an organization devoted to stopping sexual violence, while allegedly engaged in the duplicitous behavior of sharing explicit images of infants engaged in sexual activity,” Berman said, according to The Post.

“The conduct alleged against Joel Davis is as unfathomable as it is sickening,” he said, adding that “law enforcement will keep its watchful eye on the darkest corners of the internet to bring predators to justice.”
