MILWAUKEE (AP) -- Opening arguments are set to begin in Milwaukee in a federal case that could affect potential recall elections in Wisconsin.
The case involves redistricting, where lawmakers draw new maps for voting districts every 10 years to account for population changes.
The latest Wisconsin maps were drawn and approved last year by Republicans who control the Legislature.
But several Democrats and an immigrant-rights group have sued over the GOP-friendly maps. They say they're unconstitutional because they break up minority blocs, and also shift an unnecessarily large number of people from one district to another.
The plaintiffs are asking a three-judge panel to invalidate the maps. They want any potential recall elections held this year to be conducted based on the 2002 districts.
Opening arguments are set to begin Tuesday morning.
