"Oh no, it's nothing negative at all," Palin told Katie Couric Monday in the latest installment of her Monday interview with the CBS anchor. "He's got a lot of experience and just stating the fact there, that we've been hearing his speeches for all these years."
The original comments came at an Ohio rally Monday, when Palin told the cheering crowd, "I'm looking forward to meeting [Biden] too, I've never met him before - but I've been hearing about his senate speeches since I was in, like the second grade."
Watch: Palin goes after Biden
Some political observers found that comment peculiar, given her own running mate is the oldest man ever to seek a first presidential term. But Palin said she was merely contrasting the differences she sees between herself and Biden.
"He's got a tremendous amount of experience and, you know, I'm the new energy, the new face, the new ideas and he's got the experience based on many, many years in the Senate and voters are gonna have a choice there of what it is that they want in these next four years," she said.
Palin was 8 years-old when Biden was first elected to the Senate in 1972. (Biden was 29 at that time)
