In 2008, the Alabama chapter of Mitt Romney's PAC made a huge contribution to the National Organization of Marriage, the group that was pushing for a gay marriage ban in California via Proposition 8. The $10,000 donation was kept secret until this week when a whistleblower tipped off Human Rights Campaign. Romney's camp insists it was the PAC's donation, not a personal one, and though records show the money did come from the Alabama group, the donation can be tracked back to Romney's town of Belmont, Mass.
