Tagg Romney did not like it when President Obama accused his dad of dishonesty during Tuesday night's debate.
In an interview with a local North Carolina radio station Wednesday, the candidate's eldest son was asked what it was like "to hear the president of the United States call your dad a liar."
"Jump out of your seat and you want to rush down to the stage and take a swing at him," Tagg responded, laughing. "But you know you can't do that because, well, first because there's a lot of Secret Service between you and him, but also because that's the nature of the process."
He went on, "They're gonna try to do everything they can do to try to make my into someone he's not. we signed up for it, we've gotta try to kind of sit there and take our punches, and then send them right back the other way."
Tagg was also asked how his father feels before the high-stakes presidential debates.
"Are you kidding? He's terrified before he gets out there!" he responded, before correcting himself, "Terrified is too strong a word. but you know, like anybody, he gets butterflies a little bit. And then once he's in it, two or three minutes, he's forgotten about the nervousness."
