Missouri Gov. Mike Kehoe signed a new congressional map Sunday, splitting the Kansas City-area district held by Democrat Emanuel Cleaver II and adding rural Republican-leaning areas.

The move, part of a wave of mid-decade redistricting in states like Texas and California, has drawn criticism from Democrats as a partisan power grab.

The Republican-controlled legislature passed the map, but it remains vulnerable to a ballot initiative or court challenge under the state constitution.

Cleaver has pledged to run for reelection and condemned the map as unpopular, Roll Call has reported.

With recent House elections decided by narrow margins, the redistricting could influence control of Congress next year.
