Gov. Mark Dayton said Wednesday that state officials are working on a new source of money to pay the state's share of the new Minnesota Vikings stadium.

Dayton would not reveal the source of money, but said the plan does not include the team paying a larger share of the new $975 million stadium to be built on the site of the Metrodome.

The governor said the proposal does not include a plan to impose a new tax on sports memorabilia.

State leaders had counted on additional revenue from new electronic pull-tabs and bingo games, but the money has already fallen so dramatically below projections that state leader are scrambling to find another source of revenue.

Dayton said state leaders would reveal the new revenue source soon. The state needs about $30 million a year to pay its share of the stadium.
