A half-century after President Lyndon B. Johnson signed the landmark Civil Rights Act, CBS News' Bob Schieffer hosted a symposium on Americans' historic fight against segregation, and the continuing struggle for equal rights for all. In this preview, the tumultuous summer of 1964 is reviewed, when three civil rights workers went missing. It also explores the impact of the civil rights movement through first-hand accounts of the activists and public figures who continue to fight for social justice today
"CBS News: 50 Years Later, Civil Rights," moderated by Bob Schieffer features civil rights activist Harry Belafonte, U.S. Rep. John Lewis, actress Whoopi Goldberg and others. Watch the full symposium here, and more here.
