TOPEKA, Kan. (AP) -- House and Senate negotiators have resumed talks on their differences over the proposed $14 billion Kansas budget for 2013.

Three House and three Senate members met briefly Friday to exchange their latest offers. Friday was scheduled to be the final day of this year's session but legislative leaders are expecting the session to be extended.

The budget calls for spending some $6 billion in state tax dollars and fees in the fiscal year beginning July 1. It covers the expenses of most government programs.

Negotiators are at odds over how to fund increases in public schools, including how much to boost spending and the source of that funding. They also disagree on spending on social services and money to defend the state in litigation over redistricting maps.
