Speaking by phone Thursday, Paul said: “I think it shows a lack of seriousness, in regard to the problem of the deficit, if you’re willing to increase spending $190 billion dollars without cutting any spending. That is reckless and a recipe for disaster.”

“I think there’s a very important distinction, or separation, that occurred on that vote,” Paul added. “Particularly among people who are considered to be potential candidates.”

Asked about Rubio’s amendment, Paul replied: “If you are willing to increase domestic spending, without offsetting it from cuts, you know that’s liberal. If you are willing to increase defense spending without offsetting it with cuts — just simply by borrowing it — I think you’re someone who just lacks seriousness with regard to the deficit.”
