the author of this article makes valid point. Except, like most of us, we don't know the full picture either. Not saying to give the benefit of the doubt to Jared and Ivanka. It looks much more wrong than right and if it is true that a rabbi said they could travel on shabbat, why and how is that possible?
Whether Jared broke rules or not, the deal he made with the Saudis was dumb and stupid and terrible and lacks common sense for a person if he were a good Jew would know better to do the right thing.
