Griner, 32, a two-time Olympic gold medalist and star of the Women's National Basketball Association's Phoenix Mercury, was arrested on February 17 at a Moscow airport after vape cartridges containing cannabis oil, which is banned in Russia, were found in her luggage.
Russia's foreign ministry said it traded Griner for Bout, 55, a Russian citizen who in 2012 was given a 25-year prison sentence by a U.S. court on charges related to his arms-dealing career. For almost two decades, Bout had been the world's most notorious arms dealer, selling weapons to rogue states, rebels and warlords in Africa, Asia and South America.
