TOPEKA, Kan. (AP) — Kansas legislators are negotiating over the final version of a $15.5 billion state budget for the fiscal year beginning July 1. But lawmakers aren't sure when the House and Senate would vote on any agreement. Three senators and three House members had a second day of talks Tuesday without resolving any major spending issues. They planned to reconvene Wednesday. They're discussing dozens of items, but their key differences are on higher education spending and the budget for the state's court system. Lawmakers in both chambers want to spend up to $3 million to have outside consultants hunt for budget efficiencies. But negotiators said that if they strike a deal, the House and Senate still may not vote on the plan before lawmakers begin their annual spring break Saturday.
