Gov. Rick Perry plans to call another special session on congressional redistricting if the current session fails to produce a plan that increases the state's Republican representation in the U.S. House, Lt. Gov. David Dewhurst said Tuesday.

Perry earlier had told reporters he would "never rule it out," but declined to confirm that he would call a second special session on redistricting.

But Perry told Dewhurst he would call another one, the lieutenant governor said.
