NEIL CAVUTO, HOST: All right, and you know what has happened already today. Kayla Mueller has been confirmed dead, 26-year-old aid worker, killed. We just don't know when or whether it was as a result of that Jordanian airstrike in which she was collateral damage.
But I do know I am very grateful to have these two on the show today to step back and look at the value and the sanctity of life, how special it is, how fleeting it is. They know a thing or two about it, not only because back in 19 -- I think it was 1996, right, guys?
RICK SANTORUM, R-FORMER U.S. SENATOR: Yes.
CAVUTO: You lost a son born prematurely.
And, of course, they have been dealing ongoing with a child now who was all but given up for dead herself shortly after she was born. That was close to seven years ago. And she is doing just fine. And her parents are doing just fine, even after writing a book together.
CAVUTO: And that can lead to all sorts of marital discord.
I'm happy to have them with us right now.
You know that guy on the left, of course, Senator Rick Santorum. But his wife is the real -- is the real boss of this outfit.
R. SANTORUM: She is.
CAVUTO: And, of course, she had the desktop when they were writing this. He was relegated to the laptop...
R. SANTORUM: Absolutely.
CAVUTO: But, Rick and Karen Santorum, welcome to both of you.
R. SANTORUM: Thank you.
CAVUTO: And the book is "Bella's Gift: How One Little Girl Transformed Our Family and Inspired a Nation."
And we couldn't have picked better timing, guys, with this tragic news.
R. SANTORUM: Horrible story.
CAVUTO: It does make you think about life, doesn't it?
KAREN SANTORUM, WIFE OF RICK SANTORUM: My heart is breaking for them.
CAVUTO: What do you think?
K. SANTORUM: All of our heart is breaking for them.
And then to see the mother, it's extremely difficult. So, we will be praying for the family for a long time.
CAVUTO: Well, what do you tell them when they hear this and they say, what value can we place to a group that does this sort of stuff?
R. SANTORUM: This is evil. This is -- it's just these people are evil. They can call themselves whatever they want. They are evil.
CAVUTO: So when we don't heighten them to the degree we have other battles, when the president low-keys it...
R. SANTORUM: That's right.
CAVUTO: ... maybe they're not setting the whole world on fire -- the world is already on fire.
R. SANTORUM: The world is on fire.
And these people want to pour gasoline to -- not a metaphor. It's true. They pour gasoline and light that fire. And they are not going to go away based on our policies in the Middle East or anywhere else. These people have convictions about what their mission is. And it has nothing to do with what we do. It has to do with who we are.
And this is an evil that, if not stopped and destroyed, is going to continue to flourish. And that -- and this is going to be one of many things that we're going to see going forward, which is tragic.
CAVUTO: And the senator raises a good point, but, Karen, I want to raise it with you. I think -- and maybe this hits home for me more because I have a daughter about this young lady's age.
And I'm thinking, at that is someone and the family has dealt with this yourself, and now dealing with it with Bella. It's night and day, but it's still your child.
K. SANTORUM: Oh, my goodness.
CAVUTO: And you know when Bella was born, right out -- you knew right away she had something bad. What was it? What is it?
K. SANTORUM: Oh, Bella, four days after birth, was diagnosed with a Trisomy 18, which is a genetic syndrome where she has an extra 18th chromosome.
