Americans observe Juneteenth with calls for racial justice

Americans marked this Juneteenth holiday with marches and rallies nationwide. The date commemorates when the last slaves were freed in the United States, which was more than two years after the signing of the Emancipation Proclamation, and over a century and a half ago. This year’s Juneteenth served as both a day of celebration -- and an urgent call to action. Amna Nawaz reports.
