This week marks the 50th anniversary of the Supreme Court case Loving v. Virginia, which struck down the law prohibiting interracial marriage. Author Sheryll Cashin explores that case and other historical examples in her book “Loving: Interracial Intimacy in America and the Threat to White Supremacy.” Judy Woodruff sits down with Cashin to discuss economic and ideological forces at work.
