He's the Rabbi of the Western Wall, and is in charge of conduct and appearances. Every year or two he makes the news. A couple years ago it was asking a group of European clergy not to display their crosses openly, once not allowing American female Rabbis to wear tallit. He's the one who got upset, as he should, when someone removed Obama's prayer and released it to the press. A local official.
Is there a precedent for this? As for example, has the Pope ever visited a mosque, and removed his cross out of respect for the mosque?
