Ted Cruz responded Friday to an attack ad from the Dewhurst For Texas campaign which says Cruz defended a Chinese company in a lawsuit against an American manufacturer.

"As most of y’all are aware in the last two weeks, David Dewhurst has spent $2 million running saturation attack ads against me on the issue of China. You can’t turn on your television set without hearing that I’m a quote ‘red Chinese communist," Cruz said at a Tea Party U.S. Senate forum Friday. "Why is he doing this? Because he’s scared, and he’s scared because conservatives have united behind this campaign."
