Sen. Dick Durbin (D-IL) said Sunday on ABC's "This Week" that Social Security should be left alone when it comes to deficit reduction.
"Social Security does not add one penny to the deficit," he said. "Not a penny."
Medicare, however, faces more compelling near-term solvency problems, he said, but he argued that it could be adjusted without harming beneficiaries.
"Those who say don't touch it, don't change it, are ignoring the obvious," Durbin said.
