Plead guilty to two misdemeanor counts of defrauding the government in a deal he worked out with the U.S. Attorney.
Although married, a father and grandfather, Gribetz was partly done in by his former mistress, who went to the media with information about him.
Rabbi Moshe Tendler, Gribetz's longtime rabbi, said in an interview that he had often cited Gribetz in his speeches to illustrate how a devout Jew can remain faithful to the laws of kashrut and Shabbat while pursuing any career --even in law and politics.
But evidence police collected from Gribetz's ex-lover's home included whips, a dog collar, sex toys and pictures of Gribetz modeling women's clothing. Their three-year affair apparently included trips they took together funded by taxpayers' dollars.
Tendler, who organized a meeting of community rabbis to levy social sanctions against Gribetz just before his breaches became public, described the former politician's behavior as a "chilul haShem," or a desecration of God's name.
His behavior "emasculated our Torah. It reduces or minimizes the claim of Torah, that this is the divine law fit for the human experience. If someone who has been exposed to Torah does these things, what will people say?" said Tendler.
It is the reverse of what a religious Jew is supposed to do, that "the name of God shall be loved by your actions in Kiddush HaShem," said the rabbi,who is also a professor at Yeshiva University and a respected expert on medical ethics.
