Visa, Mastercard cut ties with Backpage.com in sex trafficking investigation

CHICAGO (WLS) -- Two major credit card companies are joining Cook County Sheriff Tom Dart in the fight against prostitution.

This week, Visa and Mastercard cut ties with Backpage.com. The companies made the decision after Dart asked them to stop doing business with the website.

"This is what your site is now, it is being used by these horrific people to destroy countless lives. All the different women, children, and men to some extent too who have been exploited by these sites, it is gonna be increasingly more difficult for those events to occur again," Dart said.

Dart says the battle against sex trafficking is far from over, but this will make it more difficult for criminals.
