MILWAUKEE (AP) _ Democratic candidate for governor Mary Burke says she open to the idea of public financing for a new Milwaukee sports arena, but only as a last option.

Burke said Tuesday she'd prefer to see a new arena paid for with private funds instead.

The future of the BMO Harris Bradley Center, where the Milwaukee Bucks play, remains in doubt. Bucks owner Herb Kohl announced last month he was selling the team, and he and the buyers pledged a total of $200 million toward building a new arena.

But that could still leave taxpayers on the hook for another $200 million or more.

Options include a regional sales tax, as was used for the Brewers' Miller Park, or financing from private investors who would share in stadium revenue.
