UNICEF's Catherine Russell says she saw "so much pain and misery" in recent trip to West Bank

UNICEF executive director Catherine Russell tells "Face the Nation" that she recently visited the Israeli-occupied West Bank and saw firsthand the devastation from the uptick violence, while she also met with the Israeli families of those held hostage by Hamas. "I came back feeling like, there's just so much pain and misery everywhere you look," she said.
