ABC News' David Wright Reports: At the end of a long roundtabe on credit card policy, Sen. Barack Obama was asked if he'd like to respond to Sen. Hillary Clinton's latest.
"No," he said. But then he couldn't resist.
"It's silly season," he said. "I understand she is even quoting my kindergarten teacher in Indonesia."
Clinton's campaign sent out an email to reporters Sunday saying Obama wrote a 3rd grade essay about how he wanted to be President - suggesting Obama has been plotting a run ever since.
Obama's national spokesman Bill Burton responded saying, "next she'll accuse him of flip-flopping for telling his kindergarten teacher he wanted to be an astronaut."
