Tennessee governor signs bill to protect gun manufacturers after school shooting.

Tennessee Governor Bill Lee has signed a bill that provides additional protections for gun and ammunition dealers, manufacturers, and sellers against lawsuits. The bill was passed after a deadly school shooting in March. The legislation will come into effect on July 1. The bill's sponsor, Republican Senator Joey Hensley, said that the legislation aims to help businesses in Tennessee's booming firearms industry. The firearm industry remains largely shielded from liability under federal law.
