GOP-er asks campaign rival: Why are you following my daughter on Twitter?

It was an uncomfortable personal moment at a Republican Senate primary debate Tuesday evening, when one candidate confronted his rival for following his teenage daughter on Twitter.

Nebraska Attorney General Jon Bruning brought up the issue to his opponent, state Treasurer Don Stenberg, after Stenberg criticized Bruning for supporting President Barack Obama's nominating Eric Holden for U.S. attorney general.

"Let me ask you this, Don," Bruning said. "This Sunday, my daughter walks in, and she says, 'Don Stenberg's trying to follow me on Twitter.' My daughter's 14 years old. Now you tell me, I'd like to know, why does a 62-year-old man want to follow a 14-year-old girl on Twitter? I'd really like to know. She said, 'Dad, that's kind of creepy.'

Stenberg, clearly taken aback by Bruning's question, said that one of his staffers runs his Twitter account instead of him.

"Quite honestly, I don't do my own Twitter," he said. "Dan Parsons does it for me. We've got thousands and thousands of folks, and as soon as we get done here, I'll call Dan and make sure that's taken off. I don't think it's appropriate."

Bruning replied: "Well, she's 14, Don."

"Yeah," Stenberg awkwardly said.
