Sen. Ted Cruz (R-TX) doled out some unsolicited parenting advice at a Sunday evening campaign rally, telling a heckler he’d get a “spanking” for his behavior in the Cruz household.

Cruz said, “All right, apparently there’s a young man who’s having some problems” at the La Porte, Indiana event, as the heckler shouted, “You suck!” Politico reported.

“Thank you, son,” the senator responded, according to the site.

He went on to say “children should actually speak with respect” and said it would be a “different world” if someone had taught GOP presidential frontrunner Donald Trump that lesson years ago.

“You know, in my household, when a child behaves that way, they get a spanking,” Cruz said.

Earlier this year, Cruz said former Secretary of State Hillary Clinton deserves a “spanking” for her handling of the 2012 Benghazi attack.
