President-elect Donald Trump said Thursday that Congress should get rid of the debt ceiling, a day after he came out against a deal reached by congressional lawmakers to fund the government before a shutdown occurs.

In a phone interview with NBC News, Trump said getting rid of the debt ceiling entirely would be the “smartest thing it [Congress] could do. I would support that entirely.”

“The Democrats have said they want to get rid of it. If they want to get rid of it, I would lead the charge,” Trump added.

Trump suggested that the debt ceiling is a meaningless concept — and that no one knows for sure what would happen if it were to someday be breached — “a catastrophe, or meaningless” — and no one should want to find out.

“It doesn’t mean anything, except psychologically,” he said.

The debt ceiling is the limit lawmakers set that determines how much the federal government can borrow to pay its bills. It doesn’t authorize any new spending.
