Julian Castro says he 'wasn’t taking a shot' at Joe Biden's age in health care debate

It was one of the most talked about moments of the night.

The moment Thursday night came when Castro said that because Biden's plan allows Americans to choose to participate, some 10 million people would be left uninsured. Here is the full transcript of that exchange:

You know, I grew up with a grandmother who Type2 diabetes and I watched her condition get worse and worse. But that whole time, she had Medicare. I want every single American family to have a strong Medicare plan available. If they choose to hold onto strong, solid private health insurance, I believe they should be able to do that, but the differences between what I support and what you support, Vice President Biden, is that you require them to opt-in, and I would not require them to opt-in, they would automatically be enrolled.

They wouldn’t have to buy in. That's a big difference because Barack Obama's vision was not to leave 10 million people uncovered. He wanted every single person in this country covered. My plan would do that. Your plan would not.

Biden: They do not have to buy-in. They do not have to buy in.

Castro: You just said that you just said that two minutes ago. You just said two minutes ago that they would have to buy in. Biden: Your grandmother would not have to buy in if she qualified for Medicaid --

Castro: Are you forgetting what you said two minutes ago? Are you forgetting already what you said just two minutes ago? I can't believe that you said two minutes ago that they had to buy in, and now you're saying they don't have to buy-in. You're forgetting that.

Biden: You are automatically enrolled.

Biden: That will be a surprise to him.

Several minutes earlier, Biden did reference the necessity to buy in to his proposed plan. Here is the full transcription of that exchange with Senator Bernie Sanders:

Biden: Look, everybody says we want an option. The option I'm proposing is, Medicare for all -- Medicare for choice. If you want Medicare, if you lose the job from your insurance company, from your employer, you automatically can buy in to this. You don't have, no pre-existing condition can stop you from buying in. You get covered. Period. And if you notice, nobody's yet said how much it's going to cost the taxpayer. I hear this, large savings, the president -- my friend from Vermont thinks that the employer is going to give you back if you negotiate as a union all these years, got a cut in wages because you got insurance. They're going to give back that money to the employee? Sanders: As a matter of fact, they will.

Biden: Well let me tell you something. For a socialist you got -- For a socialist, you got a lot more confidence in corporate America than I do.

After the debate, Castro told ABC News he did not regret the exchange and said “of course” he checked the transcript.

“I wasn’t taking a shot at his age," Castro said. "I was taking a shot at the fact that he had just said the words ‘buy-in.’”

“It’s not an attack on Vice President Biden, It’s not something about the personalities. It’s about the health care policy – that was my focus,” he said.
