TAPPER: In an interview last week in Rolling Stone magazine, Donald Trump said the following about you. Quote, ``Look at that face. Would anyone vote for that? Can you imagine that, the face of our next president?'' Mr. Trump later said he was talking about your persona, not your appearance. Please feel free to respond what you think about his persona.
FIORINA: You know, it's interesting to me, Mr. Trump said that he heard Mr. Bush very clearly and what Mr. Bush said. I think women all over this country heard very clearly what Mr. Trump said.
TRUMP: I think she's got a beautiful face, and I think she's a beautiful woman.
PAUL: I think one of the great problems, and what American people don't like about politics, is hypocrisy. People have one standard for others and not for them -- for themselves.
TAPPER: I want to give that -- I want to give the person that you called a hypocrite an opportunity to respond. Do you want to identify that person?
PAUL: Well, I think if we left it open, we could see how many people smoked pot in high school.
TAPPER: Is there somebody you were specifically thinking of?
PAUL: Well, you know, the thing is that...
BUSH: He was talking about me.
PAUL: Yeah, I was talking about (inaudible) -- well, let me...
TAPPER: That's what I thought, but I wanted (inaudible) to say it.
BUSH: Well, I -- I wanted to -- be -- make it easier for him.
BUSH: And I just did.
TAPPER: Governor Bush, please.
BUSH: So, 40 years ago, I smoked marijuana, and I admit it. I'm sure that other people might have done it and may not want to say it in front of 25 million people. My mom's not happy that I just did.
TAPPER: Mr. Trump, as president, you would be in charge of the Centers for Disease Control and the National Institutes of Health, both of which say you are wrong. How would you handle this as president?
TRUMP: Autism has become an epidemic. Twenty-five years ago, 35 years ago, you look at the statistics, not even close. It has gotten totally out of control.
I am totally in favor of vaccines. But I want smaller doses over a longer period of time. Because you take a baby in -- and I've seen it -- and I've seen it, and I had my children taken care of over a long period of time, over a two or three year period of time. Same exact amount, but you take this little beautiful baby, and you pump -- I mean, it looks just like it's meant for a horse, not for a child, and we've had so many instances, people that work for me.
Just the other day, two years old, two and a half years old, a child, a beautiful child went to have the vaccine, and came back, and a week later got a tremendous fever, got very, very sick, now is autistic.
I only say it's not -- I'm in favor of vaccines, do them over a longer period of time, same amount.
THE FACTS: Medical researchers have debunked claims that vaccines given to children can lead to autism and developmental disorders. The Institute of Medicine, part of the National Academy of Sciences, says vaccines are not free from adverse effects, "but most are very rare or very mild." A study that drew a connection between autism and vaccines was retracted in 2010.
TRUMP: But I have to say...
WALKER: This is actually what's wrong -- this is what's wrong with this debate. We're not talking about real issues.
And Mr. Trump, we don't need an apprentice in the White House.
We don't need an apprentice in the White House. We have one right now. He told us all the things we wanted to hear back in 2008. We don't know who you are or where you're going. We need someone who can actually get the job done.
