WASHINGTON (AP) — President Barack Obama’s chief of staff says the president will veto any last-minute debt package from Congress unless it extends the nation’s borrowing limit into 2013.

Top aide Bill Daley spoke as leading lawmakers scramble to put together a plan that could pass Congress by August 2nd and prevent an unprecedented government default.

Lawmakers are also seeking to slash the debt at the same time.

Daley was asked on NBC’s Meet the Press if Obama would veto a plan that doesn’t extend the limit into 2013, and Daley said: “Yes.”

That threat isn’t sitting well with GOP Sen. Tom Coburn of Oklahoma. He calls it “a ridiculous position because that’s what he’s going to get presented with.”
