AUSTIN, Texas (AP) — The two Republicans vying for Texas’ U.S. Senate seat accused each other of lying about their records Monday on the eve of a debate that could feature even more mudslinging as the bitter campaign roars into its final two weeks.

Tea party favorite and former state Solicitor General Ted Cruz said his opponent, Lt. Gov. David Dewhurst, lied about his record of cutting taxes while overseeing the Texas Senate since 2003 and accused him of attempting to cover up his past support of a guest worker program for illegal immigrants. Dewhurst countered that Cruz is misstating his legislative record and branded his opponent as a Washington-trained lawyer financed by Beltway insiders.
