As President Biden signs legislation to make Juneteenth a federal holiday to mark the day in 1865 when enslaved people in Galveston, Texas, learned of their freedom more than two years after the Emancipation Proclamation, we speak to the writer and poet Clint Smith about Juneteenth and his new book, “How the Word Is Passed: A Reckoning with the History of Slavery Across America.

Early voting is underway in a historic New York City Democratic primary election for mayor, 35 City Council seats and several other key races. For the first time in almost a century, New Yorkers will use ranked-choice voting, which allows them to choose up to five candidates in order of preference in each race.
