Jimmy Carter says the Trump, North Korea summit is a good idea

Former President Jimmy Carter, who said he has spent about 20 hours in detailed talks with top North Korean leaders, told CBS' Nora O'Donnell that he is glad President Trump has agreed to sit down with Kim Jong-un.

"I'm glad to hear that and I hope he will be successful. I pray that he will."

Why it matters: The decision to meet with Kim Jong-un one-on-one has widely been seen as a very risky move, given the history of negotiations with North Korea.
