ST. PAUL -- Gov. Mark Dayton and legislative leaders are abandoning their hopes of a special session.

Minnesota's top politicians have met routinely for months to try to find an agreement for an overtime session. A $260 million tax relief bill and package of public construction projects were at the top of the to-do list since the Legislature adjourned in late May.

But an ideological disagreement about building a light-rail train to the southwestern Minneapolis suburbs proved too much. Dayton said Thursday he won't call a special session this year.

Republicans dislike the project but Democrats say it's essential. The outcome means it's likely to become an issue in the fight for legislative majorities this fall.

Dayton says he'll incorporate tax and construction measures in his 2017 wish list.
