Nearly five years ago, FBI agent Robert Levinson disappeared in Iran. Over the weekend a hostage video of Levinson was given to his family. “I am not in very good health,” Levinson says on the video. “I am running out of diabetes medicine. I have been treated well, but I need the help of the United States government.” It was the first sign his family had that Levinson was alive. Christine Levinson is the wife of former FBI agent Robert A. Levinson, who has been missing for more that four years.
