In 1852, former slave and abolitionist Frederick Douglass was invited to speak at an event commemorating the signing of the Declaration of Independence. He delivered a speech that has become known as “The Meaning of July Fourth for the Negro.” In it he rebuked the country for slavery, which he called "the great sin and shame of America."

Also on the show, we'll hear from a Vermont mother who is testifying in Washington DC this week about her son's experience with a food borne illness.
