A few hours, en route at this instant. He is currently in the air being flown to Brooke Army Medical center in san antonio, texas. Thats where hell continue treatment following nearly five years in captivity with the taliban. Tonight were also learning new information about bergdahls time as a prisoner and why he may have left his platoon in the first place. The daily beast has obtained letters that are believed to be from bergdahl sent to his parents while he was being held. In a moment, were going to talk to the daily beast kimberly dozier. She is the one who got these letters from sources in contact with the taliban. She is going to tell us exactly what they say. First, though, we begin our coverage with Barbara Starr outfront at the pentagon. Barbara, what have you learned about when bergdahl is expected to return to the u. S. , the treatment that is going to await him, which i suppose could begin literally in a few hours . Thats right, erin. Good evening. All indications are he will land in san antonio in the next five to six hours. He left landstuhl in germany earlier today. Once he gets there, the treatment he has been undergoing, the socalled repatriation will continue. What we are told is it will begin to focus more and more on a few central issues. His medical, his health care, that will continue, of course. But also there will be psychological support as he moves closer to being reintegrated with his family and friends. Psychological support, there will be some debriefings, not just for intelligence gathering, but of course they want to talk to him about what happened, what led him to leave the base that night, where he believes he was taken, what were his interaction was the taliban might have been. Any intelligence, any information they can gather, but also very clearly what happened to him, what did he do. Underline all of this, though, is ultimately reunion with his family. The Family Support issues, you know, he hasnt seen any of them in so long. How to reintegrate, how to get reacquainted with your family and friends. Barbara, do you know if he has even spoken to his parents . Obviously he hasnt seen them yet. Will he see them as soon as he lands, or is that still in the future . We dont know. And we dont know whether they have spoken by phone. We do not believe so. The military has said it does not believe so. There may have been some very private communications. We just simply dont know. The family typically is expected to be at the first place back in the United States that is the typical procedure. But nothing is really ever set in stone. Were told when everybody is most comfortable with it, there will be a Family Reunion of some sort, at some point. We dont know when. It could be at the hospital. And weve seen with hostages in the past those initial family meetings can be quite overwhelming. They may only last a few minutes for the first time. All right. Thank you very much, Barbara Starr. And we have someone who just had spent years in captivity going to speak to us what that was like when he first met his family. He is with me now along with kimberly dozier, who as we said is the daily beast reporter who obtained those letters that he wrote to his family. Roy hallums is an American Contractor who was kidnapped in iraq and spent near lay year in captivity. Kimberly, lets start with those letters. What was in them . Well, there were two. One sent in 2012, and one in 2013. They are in some cases the first one is pretty rambling. It talks at first about that he is being fed, he is getting water, and then some parts of it are blocked out, presumably by the taliban. And then it goes off into a long strange diatribe about god and nature. You kind of got to wonder was he just taking advantage of this chance he had to write, and writing as long as he could after so long in isolation when he was in captivity, and then he got this brief moment. The second letter, however, he is aware of the investigation into him and why he walked off the base. And he urges his parents to tell those in d. C. Not to judge him until all of the evidence is in. He says that the conditions on his base were not safe. He complains about the orders he was given and said that both the u. S. And the afghan troops were facing risks to their lives by leaders that didnt seem to understand the situation on the ground. So it sounds like from what youre saying, kim, even in these letters, which he wrote in the midst of what appears to have been a horrific captivity in many ways, that he was aware, that he was going to be judged and was responding to that, was defending himself. Thats pretty significant in and of itself. He understood the magnitude of what now people are saying. It is. And yet ive got to play devils advocate. These were letters written under duress. We dont know. Was the taliban saying to him this is what you have to write. The handwriting in the letters is different. But u. S. Officials tell me that they did show these to the bergdahl family, and the family saw enough in them that only bowe would have known to write that they really do think they came from him. But were really going have to wait to hear from him to find out what were you thinking when you wrote this down. Roy, when you were captivity, because kimberly just said i want to play devils advocate, let me be clear here, the taliban could have been forcing him to write something. You were forced to write to your family when you were being held in iraq for nearly a year. What were those moments like, first of all . Kim was referring to maybe Bowe Bergdahl, you know, this was his moment in the sunshine or his moment in the light where he is actually able to see and write. Was it like that for you . No. The gang totally has control of what you write. When i did mine, they just set a piece of paper in front of me and gave me a pen. And one person sat on each side of me and told me exactly what words to write. And they wanted me to print it and not write in script because they couldnt read english in script. And to me, im assuming that he is in the same situation. And when youre held and theyre controlling everything you do. Right. In my case, they told me every single word to write down. And roy, when you were writing, was that a time, because i know you chained. You were kept in a very small space there was no light. Were you able allowed to come out when you wrote the letters, or did they go down in with you and basically shine just a flashlight . No, they came down in the room, took me out, set me down on the concrete floor just above where i was, which was unusual. And they sat there and they told me we want you to write a letter, and were going to tell you what to put in the letter. Kim, when you hear that, what about what roy said on the handwriting. Is that something that might make sense, that the handwriting would be different because they would force to write in all block capitals versus normal handwriting, or Something Like that. Maybe that explains why the first letter was in a sort of cursive. It was very flowery. And the second was written in block print. And it was the second letter that referred to the investigation. And it also talked about these allegedly dangerous conditions at bowes base and his disagreement with those commanding him. Maybe thats a message that the taliban wanted out there as a form of propaganda, antiamerican prop gantt da. What is going to be interesting for all of us is to eventually hear him speak for himself. Now, the pentagon tells us that that could take days, weeks, months before he chooses to tell his own story. And roy, what about you . What can you weigh in on that . You just heard Barbara Starr say we dont know at this point when he is going to meet his family, and that first meeting can be incredibly emotional and frankly too difficult for a lot of people to have last more than a few moments. When you came back, how long did it take before you were ready to see your family, and what kind of treatment did you go through to be ready for that moment . Well, i came directly back. A day and a half after i was rescued, i was back in memphis. And when i walked off the plane, the fbi had a separate room at the airport, and my family was there. So i walked off the plane and sat down and was with my family for maybe 20 minutes at the airport. And we drove back to my home. And i was with them for the rest of my time. So i was glad to see them and happy to be around friendly faces. Kimberly, was there anything from the letter that stood out to you that you would want to read . Its actually kind of hard to read the letters in terms of their grammar, their spelling is a little off. I also dont have a copyright with me. But they do talk about troopers being at risk. And they say a couple of different times wait for all the evidence to come in before judging me. And, you know, thats the one thing that Bowe Bergdahl and the pentagon seem to agree on. They all want this investigation to play out after Bowe Bergdahls debriefing and recovery ends. All right. Thanks very much, kim, roy. Thanks to both you have for joining us.

Now to a story dominating headlines, the influx of undocumented children, mostly from Central America, attempting to cross the southern border into the United States. Holding centers are at capacity, which has forced the government to open makeshift facility, and the problem isnt going away. 60,000 children as young as 4 are expected to cross into the United States this year. Our Martin Savidge is in mcallen, texas, where he got a firsthand look. Reporter its 104 in the shade in south texas, and im on the trail of the latest illegal tide crossing from mexico. The footprints give you a clue. You can see some of these are a lot smaller than us. So its either going to be females or kids. Reporter so do the life jackets littering the banks of the rio grande. They look pretty small. You got a little pair of pants right here, which obviously belongs to a child. Reporter never before say veteran agents have they seen so many unaccompanied children illegally crossing the border by the hundreds, daily. Ive seen them personally as young as 4. Ive heard of them out there as young as 2. Reporter four years old unaccompanied . Yes. Reporter back in the sweltering heat with a u. S. Border patrol agent who doesnt want to be identified for security agents. We catch up to what may be the source of the footprints. What it looks like here maybe a family unit, certainly juveniles amongst them, maybe some adults. Were going to come back here. And theyll be loaded inside. From what we understand, theyre from honduras. Many of the children are really young. Reporter the adults may be related to the children or maybe only be traveling with them. Its part of the puzzle agents have to solve. U. S. Border Protection System was designed mainly to handle adults. Local agents say it was never meant to be a detention day care. These images leaked by a texas congressmans office show massive overcrowding in just one Border Patrol station. In the closed quarters, illnesses like measles, chicken pox and scabies can easily spread. Local agents say because they are so overwhelmed, they know the drug cartels are benefitting. There is drugs coming in. There is criminals coming in. And were tied up with babysitting duties. Reporter the border is a dangerous place where heavily armed u. S. And state Law Enforcement officers are on constant alert, as we witnessed. Anybody in the water approaching a craft like this, it ramps up nerves. Reporter authorities believe this jet skier is really a cartel scout, just one more example of the risk children run on their long journey north. Do you think kids die on the trail . We know they do. Reporter he is not just an agent. Like many doing his difficult job, they are parents with kids of their own. So which part of you when you find a furryearold or you find a 6yearold interacts . It is the father side of you or the professional Law Enforcement side . Its a little bit of both, you know. You got to be a professional Law Enforcement at all times, because you never know what is going to happen. But at the same time youre a father. Youre a human being, and you have to make sure that kids okay. You have to comfort them. Now martin, thats just incredible report. Republicans, though, slamming the president , saying he is to blame for this. Im not really sure of the logic there. Others say these kids are trying to escape violence in their home countries. You mention eed honduras. What are the children telling the Border Patrol agents . The Border Patrol agents say the kids when they talk to them Say Something much more basic, which is they want to be with their mother and father that would imply of course that their mother and father is already here in the United States, and probably came here illegally as well. And that this is a family that is just trying to reunite. So its really the heart strings that are doing all of this. It is. But if thats the truth, why the surge now . Well, there are a lot of reasons for that. One of them is that it appears at least the Border Agents believe there is some kind of message that is circulating by word of mouth or resumer in Central America that now is the time to go to america. They also say that because we do not immediately return people from Central America, that that sort of encourages that kind of thinking. But i also pointed out to them, well, youre going to return a 6yearold . It did give them pause. Anything regarding kids here, it is a whole different ball game. And thats what theyre just now starting to understand. Really, really tough situation. Martin savidge, thank you very much. And now the biggest political upset of the year, the economics professor who toppled the House Majority leader finds himself thrust into the spotlight. Joe johns is out front. Reporter the College Professor who took down the House Majority leader is choosing his words very carefully. Here he is leaving his home in the richmond, Virginia Area today, dancing around the topic of immigration in this q a on the run with cnn. I dont want to do too much on policy right now. Im just the first thing we need to do, we have a disaster on the border right now, humanitarian disaster with kids. And so we need to close down the border and ill just leave it at that for right now. Reporter it looks like his biggest problem right now is handling all the attention. Republican leaders, including House SpeakerJohn Boehners office were calling, but a washington source said they couldnt get through because his voice mail was full. The state gop is pledging to give him and his threeperson staff some badly needed help, including additional people and resources for the coming election. Meanwhile, on the nearby campus of Randolph Macon college where brat and his democratic opponent in the fall, jack tram millennium are both professors, students and faculty are hoping to hold a debate wean the nominees. Students are still coming to grips with their college suddenly the talk of the nation, and their economics professor staging the biggest political upset of the year. I was amazed, shocked, excited. Reporter with strong feelings for both professors. He is not hypocritical. He believes in what he believes in. Dr. Trammel is probably the reason im here. Reporter and more than a little amusement about the celebrity this has brought to brat, including the rating he got on the ratemyprofessors. Com website with a chili pepper for being hot. I think his rating was a 3. 4. I saw that last night on the news. And personally, i think thats a little low. Reporter Randolph Macon college will soon see whether campus collegiality can overcome big money and negative political influences in a high profile congressional race.
