Paul Ryan faced a question about his Fox News interview Sunday in which he declined to offer specifics about Mitt Romney's tax plan at a town hall in Clinton, Iowa Tuesday.

"When you get into a math conversation, it can take a little while," Ryan said in response to a question about why he isn't more specific. Ryan said he would get into specifics and launched into a description of Mitt Romney's 5-point plan to jumpstart the economy at the town hall.

The woman who asked the question noted that she had watched Ryan's apperance on "Fox News Sunday" and that he had not answered a question about specifics. During that interview, pressed for details on Romney's tax plan, Ryan said that "it would take me too long to go through all of the math."
