sentences:  United States House Caucus on Missing and Exploited Children
  
  The House Caucus on Missing and Exploited Children (HCMEC) was formed in order to assist the National Center for Missing and Exploited Children (NCMEC) and coordinate United States federal legislation preventing child abduction and exploitation of children, including prosecution for possession of online pornography and solicitation of minors for sexual activity.According to statistics from the U.S. Department of Justice, of the estimated 24 million child Internet users, one in five children online is sexually solicited, yet only one in four of these tells a parent or guardian.
