A group of Republican lawmakers filed a lawsuit in state court Wednesday, Nov. 23, to block the government ethics overhaul recently approved by voters.

The lawsuit challenges the constitutionality of Initiated Measure 22, which became effective last week restricting campaign contributions and gifts from lobbyists. Gov. Dennis Daugaard says he supports repeal of the measure and he will not include money in his budget for the public campaign finance system called for by the new law.
