HARRISBURG, Pa. (AP) — Gov. Josh Shapiro is proposing a hefty an increase in aid to Pennsylvania’s schools in his first budget he’s delivering to the Legislature. But the Democrat’s administration also emphasized prudence Tuesday, saying a massive cash surplus will dwindle over time. The administration also faces demands for more money for schools, highways and social services. Shapiro addressed a joint session of the House and Senate, promising to repay voters’ trust by showing that “government can be a positive, productive force for good.” Spending would rise by 6% while Shapiro is proposing no increases in income or sales taxes. But Republican lawmakers caution that Shapiro is deficit spending.
