DALLAS (AP) -- U.S. Senate candidate Ted Cruz is ripping the attack ads run by Lt. Gov. David Dewhurst and says he won't respond with personal attacks.
Cruz spoke Friday morning in Dallas, flanked by local tea party leaders and three U.S. senators known for their tea party support.
Cruz again raised a Dewhurst flier sent to his father's home outside Dallas. The mailer has Cruz's likeness in front of a Chinese flag, a reference to Cruz's Houston-based law firm representing a Chinese company in an intellectual property dispute.
Cruz called the mailer "gutter politics" and says it questions his patriotism.
U.S. Sen. Rand Paul says he doesn't know Dewhurst, but the attack ads show Dewhurst is unfit for the U.S. Senate.
Dewhurst's campaign didn't immediately respond to a request for comment.
