Tennessee governor signs bill to protect gun manufacturers from lawsuits 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 by lawmakers after a deadly school shooting in March. The legislation expands civil immunity for gun companies, which was already in place in Tennessee. The firearm industry remains largely shielded from liability under federal law. The bill's sponsor, Republican Sen. Joey Hensley, said it aims to help businesses in Tennessee's booming firearms industry.
