Arizona- [Phoenix Business Journal]- U.S. Sen. John McCain of Arizona said Wednesday he favors greater disclosure requirements for businesses to help police investigate child pornography, human trafficking and illegal sex rings.

The presumptive Republican presidential nominee said he also supports tough penalties on Internet companies and others that fail to report child porn or trafficking information.

Federal laws already require some Internet-based businesses to report suspected child pornography and human trafficking information posted on the Web. McCain has pushed for expanding those requirements in Congress, and he said in Minnesota on Wednesday that he would make a similar push as president.

McCain also wants to crack down on international sex trafficking and pressure countries with poor human rights and religious liberty records (including trading partners China and Saudi Arabia) to improve on those fronts.

The presidential contender cites links between the underage sex trade and trafficking rings and drug cartels. The Arizona-Mexico border is a prime entry point into the U.S. for those cartels.
