Senators Manchin and Toomey draw NRA fire over their bipartisan Senate bill on background checks for gun purchases.

Sen. Toomey: "I think this debate in some ways is underscoring just the extent to which there is a polarization in our society, a political polarization, the acrimony that has gotten into politics is manifesting itself in this debate. And I think that's unfortunate."

Sen. Manchin: "What we're seeing is, is same as we're seeing in the political arena, whether you're Democrat or Republican, whether you're elected or you're running for an office, they're getting caught by different other extreme groups, really extreme groups who are putting out falsehoods and just outright lies that are not even addressed in this bill."
