Carter's Grandson Claims Credit for Publicizing Romney Video

'Twas revenge that drove him to this deed

The grandson of former president Jimmy Carter revealed he helped expose the secret Romney fundraiser video that sparked a firestorm on the campaign trail. He said his motivation "is to help get Democrats elected" and to get back at the GOP presidential nominee for his criticism of his grandfather's presidency.

"It gets under my skin– mostly the weakness on the foreign policy stuff," James Carter IV told NBC News. "I just think it's ridiculous. I don't like criticism of my family."
