Republican presidential candidate and Louisiana Gov. Bobby Jindal defended comments he made about the father of the gunman in the Oregon community college shooting and said Sunday that he “doesn’t need to be lecturing us” on gun control.

Jindal wrote in a blog post published last week that Chris Harper-Mercer’s father, Ian Mercer, was a failure who should apologize for the shooting.

Ian Mercer told CNN that the shooting wouldn’t have happened if there had been tighter gun control laws.

Jindal reiterated his stance Sunday during an appearance on ABC’s “This Week.”

“We have got a moral decay going on in our culture. We’ve got graphic violence in our movies, our video games, our TV shows. We have got senseless violence being depicted in our songs,” Jindal said. “We’ve got a culture that doesn’t value life. We’ve got millions of boys growing up without father figures, without that guidance at home.”

“He doesn’t need to be lecturing us. He, by his own admission, didn’t know how his son got those guns, didn’t know how many guns his son had, by his own admission wasn’t involved in his son’s life, hadn’t been communicating with him since he was living with his mother,” Jindal continued. “He doesn’t need to be lecturing us on gun control. We need to fix our culture. We need a renaissance of decency.”
