A controversial Texas gun group has called on activists make the Texas Republican Party convention the next front in their battle for the right to openly carry assault-style rifles as many places as possible.

Last week, the gun-rights group Open Carry Tarrant County sued City of Arlington for changing a city ordinance that made it more difficult for its members to approach motorists with pocket-sized copies of the Constitution while they were carrying rifles.

In a recent Facebook posting, the group attempted to call attention to its cause by organizing Republican delegates to bring long guns and black powder revolvers to the Texas Republican Party convention later this week.

“All delegates, I urge you to open-carry the whole time,” Open Carry Tarrant County coordinator Kory Watkins wrote. “I will be a delegate with my AK 47. Thomas Jefferson would be proud.”
