Legislative debate stretched several hours Tuesday night at the Iowa Capitol as Republican lawmakers tried to fast track votes on a bill that would eliminate most collective bargaining rights for public workers in the state. In the end, one key vote from the GOP-controlled Senate was put on hold until today after Democrats led hours of discussion over an amendment to gut the bill. That attempt eventually failed. Separately, the Republican-majority House began examining the bill Tuesday night amid procedural moves by the minority party. The House also deferred on the bill and adjourned. The legislation is similar to a 2011 Wisconsin law on collective bargaining.
