AUSTIN, Texas (AP) — University of Texas System regents are expected to consider rules allowing concealed handguns in campus classrooms and buildings.

The rules that are expected to be considered Thursday are required by a state law that takes effect Aug. 1.

The most controversial proposals have been at the flagship campus in Austin, which would allow concealed handgun license holders to carry their weapons into classrooms but not dormitories. They must have their guns holstered and may not keep a bullet in the chamber of a semi-automatic weapon.

Opponents worry that allowing guns will make campuses less safe and lead to more violence and suicide. Gun-rights groups argue that the law is a key Second Amendment and self-defense measure.

The Texas A&M System approved gun rules for its campuses in April.
