One day after top Tim Pawlenty aide Vin Weber cited Michele Bachmann's "sex appeal" as a reason the congresswoman would be hard to beat in the Iowa caucus, Bachmann responded with a joke.

When asked about Weber's comments in a radio interview Thursday, Bachmann said: "Well listen I’m 55 years old, I’ve given birth to five kids and I’ve raised 23 foster kids so that sounds like good news to me!"

Weber later apologized for his remarks, made during an interview with the Hill Wednesday:

"It's going to be very hard to beat Michele in Iowa. Period," Weber said. "She's got hometown appeal, she's got ideological appeal, and, I hate to say it, but she's got a little sex appeal too."
