GOP Leader Resigns Amid Sexual Harassment Scandal and Calls for Investigation.

Members of the Tennessee Three are calling for an investigation into what Tennessee's House speaker and his fellow Republicans knew about a sexual harassment scandal involving a prominent GOP lawmaker, Rep. Scotty Campbell, and when they knew it. Campbell resigned after NewsChannel 5 Investigates exposed the scandal. The lawmakers are also questioning how taxpayer dollars were used to cover up the actions of the former representative. House Speaker Cameron Sexton says the process for handling sexual harassment complaints needs to be reviewed, but the information is protected.
