Titled "Fed Up," the ad is airing in a number of markets statewide. In the spot, Noriega says families have lost their homes and their savings and that it's time for a new kind of senator.
Cornyn spokesman Kevin McLaughlin calls the spot "a sure sign of desperation."
Cornyn, meanwhile, debuted yet another TV spot. This one focuses on energy policy. Cornyn decries the nation's reliance on foreign oil and suggests new domestic sources can be found.
Cornyn is running for a second U.S. Senate term. The debate was being held in Noriega's hometown of Houston, where he has served as a state representative for a decade.
