If you are not a fully vested Mormon, you are not allowed to attend the part of the Mormon wedding that is inside the Temple. It dos not matter who you are, or what your relationship is to the bride. That is how it always has been, and anyone who has lived in a part of the country where there are a lot of Mormons residing knows that.
I know that Romney is part of a small 15% of Mormons who form a more secret portion of the religions leadership, and that is why the girl’s parents were forbidden to witness her marriage, after she was converted by her Governor, and married to Mitt Romney.
I am curious if a President Romney would at some point have to bring in special secret service agents who are part of that secretive Mormon group. Could that ever arise during his Presidency?
