In a column posted Tuesday on the conservative website Townhall.com, Dennis Prager blasted Minnesota Democrat Keith Ellison's decision to take the oath of office Jan. 4 with his hand on a Quran, the Muslim holy book.
Members of the House of Representatives traditionally raise their right hands and are sworn in together on the floor of the chamber. The ritual sometimes seen as the swearing-in is actually a ceremonial photo op with the speaker of the House that usually involves a Bible.

Frankly, I don't see the big deal. He's a devoted Muslim who just wants to swear his oath on his own holy book.
I'm not christian, and the swearing of oath over a bible would be meaningless for me.
