One of several bills vetoed by Arizona Gov. Katie Hobbs on Tuesday would have made it a felony for teachers or librarians to provide sexually explicit materials in public schools and libraries.
The legislation would have made it a crime to provide sexually explicit material to public school students without parental permission.
The same would have applied to public libraries that provide such materials to minors. A violation would be a Class 5 felony.
In a veto letter, Hobbs said the legislation is an attack on public schools and libraries and does nothing to protect minors.
The governor vetoed four other bills, including one that would require health care providers that offer gender transition care to pay for detransition procedures.
