The new map defining the state's Congressional districts, signed into law by Gov. Pat Quinn on Friday, will likely be challenged in federal court by Republicans.
Expected to lead the charge are former U.S. House Speaker J. Dennis Hastert of Oswego and former U.S. Labor Secretary Lynn Martin, who is also a former GOP congresswoman.
Ten of the 11 members in the state's GOP House delegation released a statement saying the Democratic governor's "actions do not match his rhetoric."
"This map will be challenged in court, and we do not expect to comment further on a matter that now will be the subject of litigation," the GOP congressmen said. "As we have said before, we do not believe this map will stand."
The only Republican congressman who did not join the statement was Rep. Tim Johnson of Urbana. He has previously said that he doesn't believe a legal challenge could succeed.
