TOPEKA, Kan. (AP) -- Kansas legislators who are struggling with redistricting are sending mixed signs about whether they're growing closer to agreeing on new political boundaries.

Senators who are negotiating redrawing the chamber's 40 districts said Friday that they were making some progress on ending an impasse among majority Republicans. But other senators suggested that the talks had all but broken off.

GOP conservatives and moderates have been at odds over how to draw Senate districts to account for changes in population over the past decade. The two Republican factions will be seeking control of the Senate in GOP primaries this summer.

Meanwhile, the House gave first-round approval to a new plan for redrawing the state's four congressional districts. Members planned to take final action Saturday.
