Mitt RomneyFormer Republican presidential nominee Mitt Romney on Sunday said that the notion of marriage should not evolve from what it was 2,000 or 3,000 years ago because only a mother and a father could provide an ideal environment for children. During an interview with NBC host David Gregory about the Winter Olympics in Sochi, Romney disagreed with Russian officials on almost every point -- except when it came to equal rights for LGBT people. "Well, I think marriage is a relationship between a man and a woman," the former GOP nominee said.
