Chelsea Clinton took Rick Warren to task over his anti-gay marriage stance in a new "Rock Center" interview.
Warren argued, "What do you expect a Christian pastor to answer -- I don't believe the Bible anymore?" He then noted, "Gay marriage might become the rule someday. That doesn't mean that I think that it's right."
Last month, Warren told HuffPost Live he wasn't a homophobe, noting that he had "many, many gay friends."
"It's not a sin to love somebody," he added. "It might be a sin to have sex with them."
