LINCOLN, Neb. -- Gov. Pete Ricketts has issued a proclamation calling a special session of the Nebraska Legislature to draw new lines for legislative and congressional districts.

The once-a-decade process is behind schedule because of delays in releasing U.S. Census data, but it will get underway Sept. 13 under the proclamation issued Friday.

In addition to legislative and congressional districts, senators will also approve new boundaries for judicial, public service commission, board of regents, and board of education districts.
