Mr. President. in a September 24 letter to the New York Times editor. Avital Shcharansky pleaded with our Nation to intervene on behalf of her husband. Mrs. Shcharansky left the Soviet Union in 1974. Her husband still remains there with 400.000 other Soviet Jews held captive. Her husband. Anatoly Shcharansky. was refused a visa in 1973. In 1977. Mr. Shcharansky was sentenced to 3 years in prison and 10 years of hard labor. Now in a work camp. his life is a misery of confinement. poor health. and isolation. His crime was his involvement in organizations monitoring the Soviet Unions compliance with the Helsinki accords.
