Carl Hart: The 12th graders said that they smoked marijuana recently. Today, that number is down to 22%.
Bill O'Reilly: Not the number that I just gave.
Carl Hart: Well, your number is wrong.
Bill O'Reilly: That senior, that ...
Carl Hart: No, your number is wrong.
Bill O'Reilly: Take it up with the National Institutes of Health, all right?
Carl Hart: No, look I . . .
Bill O'Reilly: They're the one that put it out.
Carl Hart: I am a council member on the National Institute of Health. Your number is wrong. I'm telling you it's 22%.
Female Reporter: Well, this is an interesting book. Now, I want to clarify. You're a Muslim, so why did you write a book about the founder of Christianity?
Reza Aslan: Well, to be clear, I am a scholar of religions with four degrees including one in the New Testament and fluency in Biblical Greek who has been studying in the origins of Christianity for two decades who also just happens to be a Muslim. So, it's not that I'm just some Muslim writing about Jesus, I am an expert with a PhD in the history of religions, but . . .
Female Reporter: But it still begs the question though.
Reza Aslan: I've been obsessed with Jesus.
Female Reporter: It still begs the question. Why would you be interested in the founder of Christianity?
Reza Aslan: Because it's my job as an academic. I am a professor of religion including the New Testament. That's what I do for a living actually.
Colin Powell: : I want to see a Republican Party that rather than trying to make it more difficult to vote and restricting the number of days and hours you can vote, a Republican Party that says, we want everybody to vote and we're going to give you a reason to vote for us ...
Bill O'Reilly: All right, but I don't . . .
Colin Powell: ... and for our minority population . . .
Bill O'Reilly: I don't know. I don't know if asking for an ID is trying to restrict the vote I mean, I'm sorry. You should . . .
Colin Powell: People . . .
Bill O'Reilly: . . . be able to prove who you are before you cast a ballot.
Colin Powell: No. You should be able to prove who you are when you register to vote and when you make the proper registration, identify yourself, you shouldn't have to go . . .
Bill O'Reilly: But surely you know how . . .
Colin Powell: . . . to some higher level which is going to restrict them.
Bill O'Reilly: . . . fraud is committed and I mean, Boston and Chicago, you register and then you show up and it's not you.
Colin Powell: I have not seen any study that says fraud is a problem with such significance that these kinds of procedures are in place.
Male Reporter: Does it go you know, anywhere close to the climate change debate that's underway here on earth? If the moon . . .
Bill Nye: Well, it does for me.
Male Reporter: . . . had erupting volcanoes a few years ago well, a few million years ago, however you want to put it, you know?
Bill Nye: A billion. Yeah.
Male Reporter: It's not like we've been up there burning fossil fuels.
Bill Nye: No. Volcanoes are not connected to the burning of fossil fuels.
Male Reporter: No, like . . .
Bill Nye: They're connected to mining, but the big thing for us on my side of this thing is the science is true and so when you discover . . .
the people who got really involved in climate change got involved in it often by studying Venus, the planet Venus. So, the physics, the science that happens on Venus is the same as the science that happens on the earth. The science that happens on the moon, in this case, the geology, the study of rocks that happens on the moon is the same science that happens on the earth.
So, when you say to yourself, well, I'm going to ignore all the evidence of climate change you're saying, I'm going to ignore the best ideas anybody's ever had. That's science.
Male Reporter: When you have four people dead including the first U.N. Ambassador, U.S. Ambassador in more than 30 years, how do you call that hype?
Tom Ricks: How many security contractors died in Iraq? Do you know?
Male Reporter: I don't.
Tom Ricks: No, nobody does because nobody cared. We know that several hundred died but there was never an official count done of security contractors who died in Iraq. So when I see this focus on what was essentially a small firefight, I think number one, I've covered a lot of firefights. It's impossible to figure out what happens on them sometimes and second, I think that the evidences on Benghazi has been extremely political partly because Fox was operating as a wing of the Republican Party.
Male Reporter: All right, Tom Ricks. Thanks very much for joining us today.
Tom Ricks: You're welcome.There may be small errors in this transcript.
