As the gay marriage movement begins to gain momentum, Pastor Rick Warren, best known for his best-selling book The Purpose Driven Life, is apologizing to the gay community for making comments supporting California’s Proposition 8.

During a Monday on Larry King Live, the mega-church pastor claims he “never once even gave an endorsement” of the marriage amendment only to later state that he regretted supporting it. Proposition 8 protects the definition of marriage as between a man and a woman, thereby eliminating same-sex couple’s right to marry.
