Carol Robles-Roman heads Legal Momentum, an advocacy group suing to shut down the section of the online bulletin board where children are sold for sex. 

Robles-Roman says Backpage uses an exploitive business model that pulls in millions.

“There should not be a vehicle that has made the trafficking of kids so easy, like ‘hey, do you want to order a pizza, sure, let's do that.’ ‘Hey do you want to order a kid?’ Just as easy."
