Sarah Palin is defending her attack on Democratic presidential nominee Barack Obama after accusing him of "palling around with terrorists."
The Republican vice presidential nominee on Sunday said it was legitimate to raise Obama's association with 1960s radical Bill Ayers. Ayers and Obama are acquainted, but the charge that they "pal around" is unsubstantiated.
"The comments are about an association that has been known but hasn't been talked about," she said. "It's important to talk about how Barack Obama kicked off his political career in the guy's living room."
