CBS This Morning featured a segment on the award-winning March series created by Congressman John Lewis, Andrew Aydin, and Nate Powell, calling Lewis a “civil rights superhero.”

CBS’s Jan Crawford asked the congressman about his recent trip to Comic-Con, where he dressed “in costume” recreating the trench coat and backpack he wore to march for voting rights across the Edmund Pettus Bridge in Selma, Alabama, 50 years ago. At the convention, he joined hands with local students who had studied March and led a “children’s march” through the halls of Comic-Con, with a huge crowd following solemnly behind.

CBS then sat down with the students who had marched with Congressman Lewis to find out what they’d learned from March.
