Even as Gov. Mark Dayton and top state lawmakers vow no state money to help build a new Minneapolis stadium for the Major League Soccer franchise announced Wednesday, leaders of the House and Senate are preparing to mount a push to approve Super Bowl-related tax breaks requested by the NFL.

Minneapolis is hosting the 2018 Super Bowl. Senate Majority Leader Tom Bakk, DFL-Cook, said Wednesday that last year, he and the other three top legislative leaders signed a letter to the NFL promising their best effort to secure Super Bowl-related tax breaks that several previous host cities extended.

The letter was requested by leaders of Minnesota's Super Bowl host committee and was included in their ultimately successful bid package to the NFL, Bakk said. House Speaker Kurt Daudt and Senate Minority Leader David Hann confirmed this account.

"We had an agreement we would help them try to figure out how to do this," Daudt said.

Bakk said he met a month ago with Ecolab CEO Doug Baker, a leader of the host committee. Baker told him the NFL was requesting $2.8 million in tax breaks over Super Bowl weekend, specifically in exemptions to taxes on hotel occupancy, sales taxes on NFL events and the state income taxes that team players, coaches and owners competing in the big game would normally be subject to.

"We didn't absolutely commit, but I do feel the four of us felt like now that we've got it, it wouldn't be fair not to follow through," Bakk said. He said recent Super Bowl hosts Indianapolis and New Orleans extended similar tax breaks.

Bakk said he and Daudt agree to try to find room for the provision in this year's catch-all tax bill. Daudt said even though the cost to the state is relatively small, he expects the issue to be controversial.

"If we can find a way to make that work and a way to pay for it, I'm happy to look at it," Daudt said. "Obviously it's going to require some discussion."

Dayton said Wednesday he is not in on discussions between Bakk, Daudt and the host group, though he previously had made public appearances with members of the group to tout Minnesota's bid.

"I believe that having to pay the income taxes of millionaire players and multimillionaire owners is excessive," Dayton said, openly questioning whether the provision could find sufficient support in the Legislature. Dayton said he likely wouldn't veto such a provision, but also said he would not promote it.

Details of the Super Bowl tax breaks emerged even as an official announcement came down Wednesday from Major League Soccer that it awarded a Minnesota franchise to an ownership group led by another Minnesota business titan, former UnitedHealth CEO Bill McGuire. That bid has been linked to the ongoing construction of the new football stadium, since that facility has been designed to potentiall accomodate professional soccer.

Despite that, McGuire's group is mulling a new stadium on the other side of downtown. Under the state's stadium agreement with the Vikings, team owners Zygi and Mark Wilf would have exclusive ownership rights to any soccer team that played in the Vikings stadium for the first five years.

Bakk, Daudt and Dayton have all said they do not support state subsidies for a separate soccer stadium. That has led to suggestions of pressure from the Vikings, but Bakk said that's not the case.

"We're building a stadium that can be used for soccer. We're not going to build a second one," Bakk said, adding he thinks that would be hugely unpopular with voters.

Bakk noted that the Vikings won't own the new stadium, and suggested McGuire's group could play in a temporary spot for five years before relocating to the Vikings stadium.
