From murals to portraits to photographs, a new wave of political art is emerging across the country. Artivist Nikkolas Smith tells "CBS This Morning" co-host Anthony Mason how the death of Trayvon Martin and the Black Lives Matter protested that erupted in its aftermath propelled him to process his mentions through art. Since then images created by Smith in response to social events have gone viral. Last after, the 35-year-old left his job at Disney to focus full-time on creating art.
