Sen. Mark Warner (D-VA) said Sunday that the bipartisan "Gang of Six" senators won't look to raise taxes in their recommendations for lowering the deficit, but may go after Social Security.

"We're going to make everybody mad with our approach," Warner told CBS' "Face The Nation", "because we're touching every part of the problem -- all the entitlement programs, looking at how you make Social Security more sustainable."

When host Bob Scheiffer asked him to confirmed that the group wanted to reform Social Security, he said, "You know, part of this is just math -- 16 workers for every one retiree 50 years ago, three workers for every retiree now."
