German operatives in Mexico. East German lawyer and spy trader Wolfgang Vogel was put in charge of the effort to free Zehe. He brought in Alan Dershowitz to oversee the legalities of the effort and Greenwald to act as a person liaison between him and Zehe. Greenwald visited Zehe several times in prison. During this time, he learned that Zehe was being threatened with being brought to trial under espionage charges that carried the threat of many decades in prison while being cajoled to turn over to the CIA whatever information he had that might be helpful to that agency. Greenwald conveyed messages to Zehe from his family urging him to do whatever it took to allow himself to be released as soon as possible.

As of May 2006, no fewer than 20 websites (mostly anti-Semitic sites) have alleged that Rabbi Greenwald has or had mafia connections. On March 9, 1990, a Rockland Journal News headline called Greenwald
