Just commenting because this interested me - US congressman Keith Ellison is the first Muslim to be elected to the US Congress, and so wanted to take his oath of office on the Quran. How to do this while ensuring that mad reactionary bigots only look like mad reactionary bigots (seriously, people *have* criticised him for this!) Simple - take the oath using Thomas Jefferson's copy.
One criticism - in the pictures I've seen, he doesn't appear to be wearing gloves. It's an old and historic book, I hope he used a sterile wipe first to remove the oils from his hand.
