The significance of Juneteenth, US's newest federal holiday

As of this Friday, Juneteenth — the day marking the end of slavery — is a federal holiday. Typically observed on the 19th of June, most federal employees will be able to observe it a day early because it lands on a Saturday this year. After a decades-long effort by activists, President Joe Biden signed it into law Thursday, making it the first new federal holiday since 1983. Amna Nawaz reports.
