A Moscow court rejected an appeal by Wall Street Journal reporter Evan Gershkovich against his detention, extending his stay in a high-security prison until at least the end of June. Gershkovich, the U.S. government, and his employer deny the espionage charges. The White House labeled his detention as wrongful, and The Journal called for his release. Gershkovich was arrested in Yekaterinburg last year, and despite no evidence being presented, President Putin claimed he was involved in covertly obtaining classified information. His detention is part of a pattern of American nationals being held in Russia, potentially for use in prisoner exchanges. Talks for such an exchange involving Gershkovich have been confirmed by Russian officials.
