Gov. Wolf said the bill, which would have required links or titles for every textbook and course summaries to be posted on district websites, "politicizes what is being taught in our schools.”
The law would allow parents and guardians to overrule any mask mandate imposed by the state Department of Health, a local health department, or a school board.
The response came one day after Gov. Wolf asked GOP leaders to summon lawmakers to Harrisburg to pass legislation requiring schools and child care facilities to require masks in classrooms.
