Texas Senator John Cornyn has introduced new legislation that if passed would allow concealed carry holders to travel from state to state without fear of breaking the law. The idea is similar to national reciprocity and concealed carry permits would be recognized as legal just like a drivers license.

San Antonio 1200 WOAI News Radio’s Michael Board discussed the legislation with Cornyn yesterday.

“It would allow people with a concealed handgun license in Texas to travel to other states and maintain their legal status,” Cornyn told 1200 WOAI’s Michael Board.
