The Texas State Senate has approved a bill that would allow guns in public college classrooms.
A similar measure is still stuck in the Texas House, however, with just a few weeks left in the legislative session.
The Senate bill lets students with concealed handgun licenses bring their weapons on campus.
Texas passed its concealed handgun license law in 1995. License holders must be at least 21 years old and pass a training course.
"Campus carry has more momentum than a runaway freight train," said W. Scott Lewis, with Students for Concealed Carry, a nationwide group backing the measure.
Opponents worry concealed handguns could lead to more campus violence and suicide. But supporters say it's a critical self-defense measure that could prevent campus shootings.
State Sen. Jeff Wentworth, R-San Antonio, recalled the shooting at Virginia Tech and said he wants to give students a chance to defend themselves.
"There was no one there to defend themselves in a gun-free zone that was a victim-rich zone," Wentworth said. "I'm trying to avoid that type of situation."
