On NBC News’ Meet the Press Sunday morning, host David Gregory resurrected a favorite right-wing attack on the Affordable Care Act, asking House Minority Leader Nancy Pelosi (D-CA) to defend her 2010 comment that “we have to pass the bill so that you can find out what is in it, away from the fog of the controversy.”

Gregory’s treatment of the quote was fairer than most, and Leader Pelosi handled the question capably, but it’s worth looking back to see how this became such a popular attack on Obamacare.
