Washington — A Navy veteran released from an Iranian prison last week on a medical furlough says he's sick with coronavirus symptoms and is requesting a humanitarian evacuation to the United States for medical treatment.

Michael White was hospitalized Wednesday in a crowded ward for coronavirus patients in Iran and has experienced fever, fatigue, a cough and shortness of breath since his furlough last week, according to a statement from Jon Franks, a family spokesman.

White, of Imperial Beach, California, "is an immunocompromised cancer patient and his situation is urgent," Franks said. White has been tested for the coronavirus but the results haven't come back.
