U.S. Ambassador to Russia Lynne Tracy has met with imprisoned Wall Street Journal reporter Evan Gershkovich, the envoy's fourth such visit since the American journalist was detained in March on espionage charges he denies. The U.S. Embassy in Moscow said in a social media post that Gershkovich "remains strong and is keeping up with the news." The embassy added that "we reiterate our call for his and Paul Whelan's immediate release." Russia has alleged, without providing evidence, that Gershkovich attempted to obtain military secrets while on a trip to Yekaterinburg. The Wall Street Journal denies the claims.
