GREEN BAY, Wis. – Republican presidential candidate Mitt Romney faced a tough question about his Mormon faith while campaigning for Tuesday's Wisconsin primary.

A Ron Paul supporter, 28-year-old Bret Hatch, asked Romney whether he agreed with a passage from the Book of Mormon that describes a cursing of people with a "skin of blackness." Romney's staff took away the microphone before the Green Bay man could read the passage.

"I'm sorry, we're just not going to have a discussion about religion in my view, but if you have a question I'll be happy to answer your question," Romney said Monday.
