Sen. Lindsey Graham (R-SC) vowed Wednesday not to vote to raise the debt ceiling without "real structural reforms" to Medicare and Social Security.
His statement comes in response to President Obama saying he won't engage Republican demands to increase the nation's borrowing limit like he did in 2011.
“Mr. President, I will not support increasing the debt limit until we address why we’re in debt.
“I will never vote to raise the debt ceiling unless we produce real structural reforms to save Medicare and Social Security from bankruptcy and prevent our country from becoming Greece. It is now time for you to demonstrate leadership and embrace big ideas in a bipartisan way.
"America is on an unsustainable path and to continue borrowing money without addressing our entitlement problems is irresponsible."
