Former captive: Freedom 'bittersweet'

American hiker, Sarah Shourd is happy to be back in the United States after being held for 14 months in an Iranian prison. The homecoming, as welcome as it was, is still bittersweet. Her companions, Shane Bauer and Josh Fattal are still being held. The three were arrested last year when they were hiking near the Iran-Iraq border. Sarah Shourd talked on CNN's "American Morning" about her ordeal and efforts to get her two friends free.
