 The trial of Wall Street Journal correspondent Evan Gershkovich on espionage charges began today in Russia's Ural Mountain capital of Ekaterinburg. That's the same city where the U.S. reporter was first detained by Russian security agents. For Moscow NPR's Charles Maines has more. Gershkovich faces a closed trial with no reporters, family or even U.S. Embassy representatives allowed to observe proceedings that could see him sentenced to 20 years in prison if convicted.
