"With the Legislature apparently out of time to produce a congressional redistricting plan before the session ends Monday, U.S. Rep. Joe Barton has filed a lawsuit asking a state court in Corsicana to do the job. Barton, R-Arlington, filed the suit at 12:01 a.m. Sunday in Navarro County District Court, according to his spokesman and an Austin attorney representing Barton in congressional redistricting matters.  'We're in a situation where the Legislature can't draw a map and so from our standpoint we filed a lawsuit to ask the court to draw a map,' said attorney Trey Trainor of the Beirne, Maynard & Parsons firm."
