Minnesota House Democrats pledged Monday to boycott the start of the legislative session if Republicans attempt to use their temporary 67-66 majority to take control of the chamber and elect GOP Leader Lisa Demuth as speaker.

Rep. Lisa Demuth, R-Cold Spring, proudly introduced herself as the House speaker-designate at a news conference on Monday, saying there’s no longer need for a power-sharing agreement after a newly elected Democrat resigned his seat for not meeting the residency requirement.

Republicans say that even with a temporary 67-66 majority, they plan to act as the majority. That means they’d presumably be able to establish committee control and elect a Republican House Speaker.

A major power dispute has erupted at the Minnesota State Capitol, jeopardizing the start of the legislative session next week.

Minnesota could see one of the most contested starts to a legislative session when state lawmakers meet in St. Paul next Tuesday. The DFL is threatening to skip the start of the session if there’s no power-sharing agreement with Republicans.
