An Ivy League activist who fought sexual violence has been accused of sex crimes against children

Columbia University student Joel Davis, 22, advocated for ending sexual violence. He was arrested Tuesday in New York and charged with enticement of a minor to engage in sexual activity and other crimes, federal prosecutors said.

(CNN)An Ivy League student who waged a public campaign to end rape and sexual abuse has been arrested in New York in connection with claims he intended to engage in sexual activity with children as young as 2, according to federal prosecutors.

Joel Davis, a student at Columbia University, was arrested Tuesday on child pornography and attempted child exploitation charges, said prosecutors, who based the allegations on testimony from two undercover FBI agents who allegedly exchanged text messages with Davis.
Davis, 22, founded and serves as executive director of Youth to End Sexual Violence, an international organization that claims to be youth-led and "dedicated to eliminating the use of rape and sexual violence in conflict," according to its website.
In charging Davis, federal authorities cited his public charity efforts, asserting he "displayed the highest degree of hypocrisy by his alleged attempts to sexually exploit multiple minors."
    "As if this wasn't repulsive enough, Davis allegedly possessed and distributed utterly explicit images of innocent infants and toddlers being sexually abused by adults. Crimes against children such as those alleged are taken very seriously by the FBI," William Sweeney Jr., FBI assistant director-in-charge in the New York office, said in a statement.
    Davis, who lives in Manhattan, was charged with enticement of a minor to engage in sexual activity, attempted sexual exploitation of a minor, possession of child pornography and distribution of child pornography, court records show.
    He has not entered a plea, court officials said. If convicted on all counts, he could face the maximum of life in prison, prosecutors said.
    CNN's attempts to reach an attorney for Davis on Thursday were unsuccessful. Youth to End Sexual Violence did not immediately reply to CNN's request for comment.

    The organization Davis founded is listed among the "renowned human rights experts and civil society leaders" that make up the steering committee of the International Campaign to Stop Rape & Gender Violence in Conflict. The group, which claims to foster partnerships between Nobel Peace laureates and international advocacy organizations, has not responded to CNN's request for comment.
    Davis in April was described as an "activist and survivor" on a list of 22 planned speakers for a TEDx event at Columbia. The event was organized independently of its namesake TED organization, known for its TED Talk lecture series.
    Davis also was described by his university's student newspaper as an activist working to end sexual violence against children. Davis contributed at least six columns last year to the publication, the Columbia Daily Spectator, including one in which he claimed he endured sexual abuse as a child.
    Further, Davis claimed on his LinkedIn online resume to have served as a youth ambassador for the United Nations in the role of special representative on sexual violence in conflict. However, the intergovernmental organization's top executive on Thursday said that office "has no formal relationship with Mr. Joel Davis" and "does not have any so-called Youth Ambassadors or equivalent title," according to a statement issued by spokesman Stephane Dujarric.
    Davis had, in the past, attended UN events on sexual violence issues, and "he is one of numerous activists who has come through the Office over the years," the statement
