Fox's Chris Wallace Tells Paul Ryan That Obamacare Repeal Is 'Not Going to Happen

House Budget Committee Chairman Paul Ryan (R-Wis.) will present a budget this week that's based on the repeal of President Barack Obama's Supreme Court-approved health care law.

"By repealing Obamacare and the Medicaid expansions that haven’t occurred yet, we’re basically preventing an explosion of a program that is already failing. So we’re saying don’t grow this program through Obamacare because it doesn’t work,” the 2012 Republican vice presidential nominee said on "Fox News Sunday."

Fox News host Chris Wallace challenged Ryan about repeal, stating flatly: "Well that's not going to happen."

“Well, we believe it should," Ryan said. "That’s the point. This is what budgeting is all about. It’s about making tough choices to fix our country’s problems. We believe that Obamacare is a program that will not work."

Regarding his potential plans for 2016, Ryan in no way dismissed a White House bid out of hand.

"I honestly think that we have a problem right now, that's a budget mess," Ryan said. But once that's no longer an issue, "I'm going to give serious thought to these other things."
