Sen. Bob Casey is making a brief appearance on "OutFront with Erin Burnett" on CNN. The topic is extending the payroll tax cut. Casey says this is one of the ways to jump start the economy, to keep things moving. When asked if the tax cut needs to be paid for he said that would be preferable. He says he had proposals to pay for at least part of it when the extension came up earlier, but it was rejected by the GOP. Says congress did a lot of cutting last year and could do more.
