Child trafficking is an increasing problem in the United States. It was less than a month ago that FBI Director James Comey arrested 281 suspected pimps and rescued 168 children in a sex trafficking sting.

The House Committee on Education and the Workforce held a hearing Tuesday to discuss other potential solutions to stop these tragic crimes.

"The Internet has increased the risk of youth sexploitation and Internet crimes against children and child pornography cases continue to rise," said Rep. Dave Loebsack, D-Iowa.

One in seven missing children are being sexually exploited and according the the National Center for Missing and Exploited Children, 67 percent of those children are coming from foster care.

"Right now only two states have laws mandating the reporting of children missing from foster care," said John Ryan, President and CEO of NCMEC.

Five bills passed the House of Representatives in May and are now waiting for approval by the Senate.

Those bills are aimed at creating more protection for foster children, stopping child sex trafficking and dealing with the online marketplace for such crimes.
