Gov. Katie Hobbs vetoed two bills that aimed to promote school safety on campuses throughout Arizona.
House Bill 2332 would have required "one or more" firearms safety "training sessions" for Arizona students in grades six through twelve, and Senate Bill 1331 would have let parents with concealed carry weapons to bring them onto campuses.
"Mandatory firearm safety training in school is not the solution to gun violence prevention," Hobbs said in a Monday letter.
"Allowing more guns on campus will not make a campus safer. Firearms on campus have the potential to confuse law enforcement as they arrive at an active shooter situation," she added.
The vetoes come as the debate between Democrats and Republicans over how to stop mass shootings at schools continues, especially following the recent shooting at a Christian school in Nashville, Tennessee. The Associated Press estimated in March that 175 people have died in a mass school shooting since the Columbine High School shooting in 1999.
