The CBO said very clearly that if you were to adopt the president's plan, there would be a $2 trillion hole in Social Security, because today's workers pay in to the system for today's retirees. And the CBO said -- that's the Congressional Budget Office; it's bipartisan -- they said that there would have to be a cut in benefits of 25 percent to 40 percent.
The CBO is short for "Congressional Budget Office."
