HARRISBURG, Pa. - A bill that would allow parents in Pennsylvania to exempt their children from wearing a mask at school cleared a state Senate committee on Tuesday as Republican lawmakers started making good on their pledge to counter the governor’s statewide mask mandate.The legislation would hand the ultimate decision on masking at school to parents and guardians, allowing them to overrule any face-covering mandate imposed by the state Department of Health, a local health department or a school board.It would also prohibit schools from keeping unmasked students away from other students or excluding them from any school-sponsored activities.The Senate Education Committee approved the bill on a party-line vote.
