Veterans aid Afghans escaping the Taliban

When Afghanistan fell to the Taliban last year, Afghans who had helped the U.S. during the war were targeted for retaliation. CBS News national security correspondent David Martin talks with Elliot Ackerman, author of “The Fifth Act: America’s End in Afghanistan,” who became part of a digital network of veterans working to get Afghans out, about their efforts to help one Afghan and his family to safety.
