• Iowa Republican legislative leaders have filed a lawsuit against Governor Tom Vilsack, challenging his use of a line-item veto on economic-development legislation approved earlier this year. The lawsuit in Polk County District Court, which names House Majority Leader Christopher Rants and Senate Majority Leader Stewart Iverson as plaintiffs, stems from Vilsack's June 19 selective veto of income-tax cuts, changes in the worker's compensation system, and limits on some jury awards.
