DES MOINES — Partisan leaders in the House and Senate said Thursday they are making progress on issues holding up adjournment, but they remain far apart on fiscal 2016 budget differences that could slow the process for shutting down in May.“We’re moving forward. We’re making progress. Bills are coming out of committee,” said House Speaker Kraig Paulsen, R-Hiawatha.Paulsen and Senate Majority Leader Mike Gronstal, D-Council Bluffs, said it was a positive development that Republicans and Democrats have come out with fiscal 2016 spending targets that will form the basis for future negotiations, although compromise continues to elude them.“We are moving forward with a budget that we think reflects Iowa’s priorities,” Gronstal told reporters Thursday.
