Zika in Florida; Interview With Former Homeland Security Secretary Janet Napolitano
BALDWIN: Breaking news out of Florida here when it comes to the Zika virus We now know, according to officials, that mosquitoes carrying the virus have been identified in, of all places here, Miami Beach. Three mosquito samples tested positive for the virus. This is a big deal because this is the first conclusive proof of Zika-carrying mosquitoes in all of the United States. These are samples, they were collected from the same area of Miami where the virus has been spreading. So, I have got Dr. Sanjay Gupta with us. He's a CNN chief medical correspondent who has been covering Zika for a while now. We have been talking about human -- or people, I say, with Zika in Miami, but now we are talking, Sanjay, mosquitoes.</s>DR. SANJAY GUPTA, CNN SENIOR MEDICAL CORRESPONDENT: Yes, Brooke, that's exactly right. And I will preface by saying, Brooke, that I think, in many ways, this was expected. We knew that there was what is known as locally transmitted Zika infections. And what that means is -- we have been talking about this for some time, is that we know that people who were getting Zika in the United States prior to what we have been seeing in Florida, they got it because they traveled to a place where Zika infection was located. And they brought it back. But the thing that they have been on the lookout for, for some time is local transmission, meaning mosquitoes actually biting someone who has the Zika virus in their system, carrying the Zika virus in the mosquito's body, and then biting someone else. And that's local transmission. They knew that it was happening because they already identified people who have not traveled and yet still had the infection. But now, as you point out, Brooke, they have found mosquitoes that also contain the Zika virus. Again, not surprising. It is a little stark reminder, but not a surprising one, because we knew that this was already happening.</s>BALDWIN: All right, Sanjay, thank you so much for jumping on the phone on the breaking news out of Miami Beach. Thank you for that. Let's get back to politics here and Donald Trump. Donald Trump is doubling down on his signature campaign proposal to build that wall right along the U.S.-Mexico border. And he said it over and over. He wants Mexico to pay for it. In a major address on his immigration plan, Mr. Trump said that Mexico would pay for the wall 100 percent. But the president of Mexico, with whom he met just yesterday, President Enrique Pena Nieto, says, no. Pena Nieto says that during his meeting with Trump behind those closed doors that he made it crystal clear that Mexico would not be footing the bill. Trump, for his part, says the wall wasn't discussed. So, even so, here at CNN, we have been looking into what it would actually take, the feasibility, the practicality, to build a wall. Here is national correspondent Jason Carroll.</s>JASON CARROLL, CNN NATIONAL CORRESPONDENT: You're talking about an area 1,954 miles stretching across California, Arizona, New Mexico, and right here in Texas, just about 100 yards away from Mexico. The experts that we spoke say the way to go is precasted cement wall panels. Those panels would be lined side by side, sort of like what you might see on a highway. Each panel would be about 20-feet high, again, five feet below ground, about 10-feet wide, and eight-inches thick. Again, that wall would be stretching some 2,000 miles. And our expert says it would require 339 million cubic feet of concrete. And that's just for the panels. You're also going to need reinforced steel, at least five billion pounds. So, what about the estimated cost? Because it hasn't been done before, let's use those highway panels as an example. They cost about $40 a square foot. That would end up costing about $10.5 billion. Sounds like a lot of money, is a lot of money. But, again, remember, Donald Trump says the U.S. government wouldn't end up footing the bill on this one. It would be Mexico. And what about the timing on all of this? How long would it take to build? According to our expert, if you are ambitious, you could get it done within a presidential term, four years.</s>BALDWIN: Jason Carroll, thank you. Here she is. I'm joined by former Homeland Security Secretary and former Arizona Governor Janet Napolitano. She is now the president of the University of California system. Secretary Napolitano, thank you so much for taking a minute with us. We appreciate it.</s>JANET NAPOLITANO, FORMER U.S. HOMELAND SECURITY SECRETARY: Thank you.</s>BALDWIN: So, as someone who grew up in a border state, governed a border state, now lives in another border state, I have to ask you, what do you think of the wall?</s>NAPOLITANO: You know, we have heard the wall idea for years. And I remember, in 2004, when I was the governor of Arizona, the wall idea was around. And I said basically, show me a 10-foot wall, I will show you a 12-foot ladder. That's not the way you do border enforcement. And the amount of resources it would divert from a real border plan that involves more manpower, technology, air coverage, all the things that are now in place currently at the U.S.-Mexico border, and we know that illegal migration across that border is the lowest it's been in decades.</s>BALDWIN: Is there anything about Mr. Trump's immigration plans that seem admirable, palatable, realistic to you?</s>NAPOLITANO: Very little, to be quite frank. And I will point out two other areas that I found unrealistic or unfair, not wise. One was to repeal the president's executive order allowing young people who have grown up in this country, who are here undocumented, to stay in this country. They get their education. We have probably 3,500 or 4,000 of these so-called DACA students at the University of California. These are wonderful young people. They will contribute a lot to our country. They are the so-called dreamers. That's how they're known in the vernacular. And it's -- it would be such a shame to repeal those orders. And a second area that I find I can almost say un-American is this idea that you are going to do an ideological test on people...</s>BALDWIN: Right, the screening.</s>NAPOLITANO: ... before they emigrate into the United States. First of all, there is a lot of vetting that goes on, particularly from areas of the world that -- where there is a lot of conflict. And that's never reported on enough. But the amount of vetting that already occurs is quite substantial. But how do you do an ideological test? That's not the way America has always viewed itself.</s>BALDWIN: Well, that's a question people are asking. I hear three examples of, to use your word, un-American ideas from Mr. Trump. But what about his visit to Mexico? I have to ask you about that. We know the former Mexican President Vicente Fox called the current Mexican President Enrique Pena Nieto a traitor for even having Trump to the presidential palace, to Mexico. Do you think the current president got burned by Trump?</s>NAPOLITANO: I was surprised that he invited Mr. Trump. And I will say this, however. If all they talked about was a wall, what a missed opportunity for Mr. Trump to actually engage in a substantive conversation with the president of Mexico on all of the issues that we share, for example, trade between the United States and Mexico. It's the second or third leading trading partner with the United States. How do we operate those legal routes of traffic? How do we run the ports of entry along that 2,000-mile border. That's just one area where we have a lot to discuss with the leadership of Mexico.</s>BALDWIN: OK, so missed opportunity, you say. What about Arizona? You have Sheriff Joe Arpaio, who said -- back to the wall -- who says he doesn't care who pays for this wall. Did the sheriff give Trump an out?</s>NAPOLITANO: You know, he may have. But...</s>BALDWIN: He may have.</s>NAPOLITANO: You know, I don't know. Sheriff Arpaio's been down there forever. But, again, this is a sheriff now who is -- has been found --
