Democratic gubernatorial candidate Tom Wolf says he'd look to increase income taxes on Pennsylvania's higher earners to expand the state's share of public education funding.

In an interview with a panel of Associated Press reporters and editors Friday afternoon, Wolf says he'd tie the increase to a dollar-for-dollar reduction in local property taxes levied by school boards.

Wolf's goal would be to raise the state's share of public school costs to 50 percent.

That's a shift of several billion dollars a year. It currently pays about one-third, while property taxes shoulder more than 40 percent.

Wolf's plan to reshuffle school funding would accompany his proposed overhaul of the 43-year-old income tax to target higher earners.

Wolf is challenging Republican Gov. Tom Corbett in the Nov. 4 election.
