Mr. Rezaian was born in California and holds dual citizenship in Iran and the United States. He was imprisoned in July 2014 and convicted in October on charges that included spying. The length of his sentence was not publicly disclosed.
Executives of The Washington Post, who say Mr. Rezaian is innocent of any wrongdoing, have described his prosecution and imprisonment as a Kafkaesque farce. Executives from 25 news organizations recently sent a letter to Secretary of State John Kerry urging him to press Iran to release Mr. Rezaian.
