Texas allows guns in college classrooms

In this Oct. 1, 2015, file photo, protesters gather on the West Mall of the University of Texas campus to oppose a new state law that expands the rights of concealed handgun license holders to carry their weapons on public college campuses. University of Texas President Greg Fenves has approved rules that will allow concealed handgun license holders to bring their weapons into classrooms. State law requires public universities to allow concealed handguns in classrooms and buildings starting Aug. 1, but also gives campuses some leeway to carve out gun-free zones.

Factoid: Idaho approved a law last year that allows concealed weapons on college campuses in the state.
