Clayton M. Christensen, a Harvard Business School professor and Romney supporter who holds a leadership position in the Mormon Church, saw the decision as a sign that Romney is making a serious bid to become the first Mormon president.

"I'm delighted that he's decided to do it," Christensen said. "It really is a great church, and the more people can understand what it is and what it does, the more I think they'll trust that he acts in the best interests of the country."
