WASHINGTON (AP) — American basketball star Brittney Griner is heading home, freed from Russian prison in exchange for the U.S. releasing notorious Russian arms dealer Viktor Bout. Thursday’s dramatic action was the culmination of an eight-month saga of high diplomacy and dashed hopes. But the U.S. failed to win freedom for another American, Paul Whelan, jailed in Russia for nearly four years on espionage charges that his family and the U.S. government say are baseless. The swap comes at a time of heightened tensions over Russia’s invasion of Ukraine. And it has brought unprecedented attention to the number of what the U.S. considers wrongful detainees.
