Texas Lieutenant Gov. Dan Patrick said parents and students affected by the Santa Fe school shooting told him they would support arming teachers as a defense against a gunman.

Patrick said the Texas state government already allows teachers to be armed, leaving the ultimate decision up to each district's superintendent.

"They all said 'we want to arm our teachers,'" he said.

Patrick said a retired Marine was serving as a substitute teacher and barricaded his class inside their room after hearing the gunshots.

However, he said such a teacher could have properly engaged the gunman if he were armed.

"He may have stopped the shooter," Patrick said. "The answer is not taking away guns."
