 Gershkovich's trial is taking place behind closed doors in the Ural Mountain capital of Ekaterinburg. It was there that the Wall Street Journal correspondent was arrested while on a reporting assignment in March of last year. Prosecutors accused Gershkovich of trying to gather state secrets from a nearby tank factory. He faces a possible 20-year prison sentence if convicted. Gershkovich, the Journal, and the U.S. government all vehemently deny the spying charges.
