TOPEKA, Kan. (AP) -- Three federal judges have collapsed a Kansas Senate district in the north-central part of the state so that a new one could be drawn in the growing Kansas City suburbs.

Senators were still reviewing the new lines Friday, a day after the judges issued their order in a lawsuit over the Legislature's failure to pass any redistricting proposals this year. The judges adjusted political boundaries to account for population changes over the past decade.

There's a new 21st District in Johnson County because of population growth there. That number used to belong to a north-central Kansas district, but it has been collapsed.

The changes throw Republican Sens. Roger Reitz, of Manhattan, and Mark Taddiken, of Clifton, into the same district. But Taddiken has announced he's not running again.
