CORTEZ MASTO: These streets can be tough, and too often they're the end of the road for vulnerable young women. Nevada has a serious crisis -- the sex trafficking of teenage girls. As attorney general, I made it my mission to fight back -- increasing prison time for pimps and predators, expanding the sex offender registry, and giving victims the right to sue their captors. I'm Catherine Cortez Masto. I approve this message because I know we can make a difference to save these young lives.
