Gov. Tim Pawlenty is proposing an amendment to Minnesota's constitution on Thursday.
The Republican governor will announce details at a morning news conference at the Capitol.
Pawlenty spokesman Brian McClung says the proposal is related to economic issues.
Minnesota governors can propose constitutional amendments but they don't have much to do with approving them. Proposals must pass the Legislature and then win approval from a majority of voters to become part of the state constitution.
Democrats control both houses of the state Legislature.
