Missouri lawmakers have until Friday to finalize the state's roughly $25 billion operating budget. The House and Senate have each passed their own budget and now must hammer out an agreement on the spending plan that will take effect July 1st. Budget negotiators are expected to begin formal talks today. One item not up for debate this week is Gov. Jay Nixon's plan to draw down nearly $1 billion from the federal government to expand Medicaid coverage for about 260,000 adults. Neither the House nor Senate included the federal money in their proposals.
