The ad starts off showing childhood photos Steve Ronnebeck's son.
 
"My son, Grant, was killed working an overnight shift at his job by an illegal immigrant," Ronnebeck says in the ad. "He was out on a nice bond. He should have been deported." 
 
Ronnebeck said his son's death was "completely preventable."
 
He said he trusts Cruz because the Texas senator believes in our "Constitution" and the "rule of law."
 
"It's time we put somebody in office who puts the American people first," he said.
 
Ronnebeck's son was reportedly shot by an illegal immigrant in 2015 while he was working an overnight shift at a convenience store in Mesa, Ariz., The Arizona Republic reported. A man handed Grant Ronnebeck change and asked for a pack of cigarettes. The man then shot him after he attempted to count the money.
