Gershkovich’s parents and U.S. ambassador to Russia Lynne Tracy attended the hearing. Speaking to reporters afterward, Tracy said that “Evan continues to show remarkable strength and resilience in these very difficult circumstances.”

Gershkovich and his employer have denied he spied in Russia. The U.S. government has declared him to be wrongfully detained and demanded his immediate release.

His arrest in the city of Yekaterinburg rattled journalists in Russia, where authorities have not detailed what, if any, evidence they have gathered to support the espionage charges.

Gershkovich is being held at Moscow’s Lefortovo prison, which is notorious for its harsh conditions. U.S. Embassy officials were allowed to visit him once, but Russian authorities rejected two other requests to see him.

Russian Deputy Foreign Minister Sergei Ryabkov told reporters on Thursday that the ministry is considering another visit request from the embassy.
