He spoke about this while he was on with Megan Kelly on Fox Friday night. Megan Kelly also referred to the media hypocrisy for talking about the issue like anyone against gay marriage is some kind of bigot living in the stone age when Barack Obama, Joe Biden, Hillary Clinton were all against gay marriage until a few years ago.
Further update on what he actually said."And my question that I would love to pose to the president is this: Mr. President, please explain that when you said in 2008 at the Saddleback Church forum that you stood for traditional marriage and you did so because you were a Christian and because it’s what the Bible taught, please answer: Were you lying then, are you lying now, or did the Bible get rewritten?”"
