Republicans are defending Missouri's newly redrawn U.S. House districts in court.
Experts are testifying in the Supreme Court right now after several cases were filed protesting the state's new redistricting maps.
Meanwhile Governor Jay Nixon has appointed a new commission to re-draw new state Senate districts.
The new commission will hold its first meeting Feb. 18 in Jefferson City.
District boundaries were redrawn to account for changes in population since the 2000 census.

It's back to the drawing board for lawmakers who created new redistricting maps.
The Missouri Supreme Court struck down new state Senate district maps and ordered further legal review into new U.S. House districts.
Tuesday's rulings add uncertainty for the 2012 election year, just weeks before candidates begin to file for office.
That means the redistricting process must start over, with the governor appointing a new, bipartisan citizens commission to draw Senate boundaries.

Missouri's new Senate redistricting map went to the state Supreme Court.
The court heard arguments in two cases challenging the new congressional map, which reduces Missouri from nine house districts to eight.
One case contends the map, approved by the republican -controlled state legislature was designed for partisan reasons.
The other suit focuses on the oddly-constructed fifth district.
