Sen. Rand Paul, R-Ky., introduced legislation on Thursday that would repeal a 1990 law banning guns from school zones, a move that fits with his push to arm teachers and other school personnel so they can prevent school shootings like the one that took place in Florida last month.

Paul's bill would repeal the Gun-Free School Zones Act of 1990 and all amendments to that law.

The law bans weapons in and around all public and private K-12 schools, with limited exceptions. Its supporters say the law is needed to reduce violence at schools.

But Paul is a long-time advocate of allowing some teachers to be armed, and has argued along with other conservatives that current law makes schools easy targets for mass shootings.

In early 2013, just weeks after the Sandy Hook shooting that left 26 people dead, including 20 elementary school kids, Paul said it was time to arm teachers.

"If my kids were at that school, I would have preferred that the teacher had concealed-carry and had a gun in her desk," Paul said then, according to USA Today.

"Is it perfect? No. Would they always get the killer? No. Would an accident sometimes happen in a melee? Maybe. But nobody had any defense, and he just kept shooting until he was tired and he decided to shoot himself," he said of the Connecticut shooting.
