NUNN: David Perdue is running ads saying that while I led President Bush's Points of Light Foundation, we funneled money to terrorists. That's a terrible lie and an insult to the millions of volunteers I worked with to make a difference. David Perdue's ad has been called the worst in America, and President Bush's son called it shameful. I'm Michelle Nunn. These kind of attacks are what's wrong with politics. I'm determined to bring decency to Washington. That's why I approve this message.
