U.S. Rep. Emanuel Cleaver, D-Kansas City

U.S. Rep. Emanuel Cleaver, D-Kansas City, testifies Thursday against a redistricting plan that would gerrymander his district in favor of Republicans.

U.S. Rep. Emanuel Cleaver warned Missouri lawmakers Thursday that the effort to redraw the 5th District seat to favor Republicans will be long remembered by voters who resent being swapped by politicians seeking to increase their power.

Speaking to the Senate Local Government, Elections and Pensions Committee, Cleaver, a Kansas City Democrat, noted that Texas has already revised district lines this year to favor Republicans and California will vote later this year on a plan that favors Democrats.
