Jimmy Carter's grandson: Family honor prompted him to help leak Romney video

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

In the video, Romney can be heard describing Obama supporters as people who are "dependent on the government" and "believe that they are victims." The Republican candidate also downplays any chance of a peace agreement between Israel and the Palestinians, who he says are “committed to the destruction” of Israel.
