(CNN) Florida Gov. Ron DeSantis has signed a bill that would allow teachers to be armed on campus.

The controversial school safety bill arrived on the governor's desk after passing the Florida House last week.

Rep. Dane Eagle, who supported the bill, said it does not mean all teachers will have weapons at their disposal.
