Personnel changes and recently phoning midlevel officials to angrily demand that they do more to stem the flow of immigrants into this country. Lets start at the white house with nbcs hans nichols. A very, very busy day. Would have been a busy day under normal circumstances and then you have the announcement of the departure of the head of the secret service. What do we know about this . He is a 40year veteran. Pete williams is telling us that alles departure isnt tied to any specific event and certainly not tied to what happened at maralago a few weeks ago when you had the Chinese Nationalist trying to sneak in. We have a new name. James m. Murray. Career secret service official. He has down counterterrorism and fraud cases looking through his background. He appears to be just a career person that is coming through. Now, overlaying all this is what is happening at dhs and there is uncertainty there. Nielsen be out on wednesday and the president announced his intent to have a acting new one on wednesday and heres what Kirstjen Nielsen said when she spoke to the cameras earlier today. I want to thank the president for the tremendous opportunity to serve this country. Im forever grateful and proud of the men and women of dhs who work so hard every day to execute their missions and protect the homeland. I really look forward to continuing to support them from the outside. I will continue to support all efforts to address the humanitarian and security crisis on the border. So, ali, we had to bone up on the sort of vacancy act as well as what succession means and all the various statutes. But a domino effect taking place at dhs. You have Clare Mcgrady currently the number three. Thats the succession act law that she would then therefore be moved up and have to be acting and that you couldnt have him super seed him. What we are trying to figure out is theyre trying to do something with clare xwrad grad reassign her so the president can get his pick in place. But gives you an indication that they may not have thought entirely through all the moving parts on this. Meanwhile, as you mention, you have so many vacancies throughout dhs and now youre going to have a change of a top of secret service. Ali . To the point that katy and i were just talking about. Steven miller who have views on administration to say outside the main stream would be an understatement. The senator from South Carolina has said that he is outside even conservative main stream in his thinking. But he seems to be ascended in his influence with donald trump. Look for a former sessions aide and we all know what happened to mr. Sessions when he came into this administration, Steven Miller had an extraordinary amount of power. Whenever there is shifting and moving things in any white house whether theyre doing a fundamental reorganization or longstanding grievances are being carried out, important not to assign too much power to one individual. At the end of the day, its always the president that drives it. This is clearly a president that has no problem either publicly humiliating his cabinet members and his staff and or letting them go without a contingency plan. What we know so far is that the planning for succession at dhs doesnt appear to be going that smoothly and some legal questions that theyre still trying to sort through here. Ali . Hans, thanks for your reporting. On wednesday, Homeland Security secretary Kirstjen Nielsen will be out of her role and replaced by the border and custom protection. Particularly because of secretary nielsens defense of this Administration Policies including family separation that she has faced calls to resign before. We have a secretary in place, secretary Kirstjen Nielsen whose role it is to provide leadership for the department of Homeland Security. What weve seen instead of leadership and Real Solutions is an implementation of Donald Trumps policies of cruelty. By the way right now on your show, im calling for the secretary to resign. Her incompetence is hurting the community. Its hurting this country. The democratic congresswoman from texas joins me now. Representative veronica escobar. Congresswoman, this is inest the inesttrusting. You called for her resignation. Little did we know it would come because she was not considered tough enough by donald trump on the border. Your thoughts . I mean, i will tell you, a number of people who have said, hey, be careful what you wish for. The next person in line could be worse and while that is absolutely true, that does not mean we dont call out people who have been the enforcer of the cruelest immigration policies of our generation. It was important to call her out. It was important to remove her. And i think its very important for us to bring to light a couple of things. Number one, that her replacement, there should be absolutely no role for furthering family separation. That there should be Real Solutions. For example, instead of using highly paid, highly trained agents to hand out diapers and burritos to people who are in refugee camps in this country, we should have social Service Workers doing that work instead. Getting our agents back on the front lines. Secondly, weve got to bring forward legislation that is compassionate and humane. Were working on that. We need to stop the attempts to circumvent the law and the attempts to rewrite the law in a way that is more cruel and more limiting. Weve knot to bring forward and we are working on that alternative solutions and real ideas so that we can address what is a monumental challenge for sure to be sure. But one that has been made worse by incompetence and cruelty. Lets just remind everybody of the times that secretary nielsen has defended these policies youre talking about. Listen with me. The exclusive product of loopholes in our federal immigration laws that prevent illegal immigrant minors and family members from being detained and removed to their home countries. In other words, these loopholes create a functionally open border and apprehension without detention and removal is not border security. As you sit here today, you do not know how many human beings have died while in the custody of the department that you lead. And you, in preparation for todays hearing, you didnt ascertain that number but you dont know it today. I dont have an exact figure for you. Do you have a rough idea . Sir, what i can tell you im talking about people who have died in your custody. You dont have the number. What we do know we have stopped over 3,000, what we call special interest aliens trying to come in the country on the southern border. Those are aliens who the Intel Community have identified are of concern. I just want you to admit that the cages exist. Sir, theyre not cages. What are they . Areas of the border facility that are carved out. I dont know where to start with that. The 3,000 special interest aliens turned out to be a lie. And youve seen the ways in which people are detained in texas. What is your response to this and your fears about what happens next . Well, you showed some snippets of someone who has repeatedly lied to congress and the american people. Its about time that we are honest with one another. When ive spoken with many of the families who are running from violence and crushing poverty and persecution, theyre not running because theyve heard that there is some loophole that exists, theyre running for their lives literally. And the sooner we understand that and the sooner we have leadership convening the leaders of this hemisphere because this is a shared challenge and its going to take collaboration and its going to take ownership. The sooner we can do that, the sooner we can really achieve some workable solutions. But we also have to be honest with ourselves. A lot of the women that i spoke to on friday when we had yet another congressional delegation visit el paso. Many of those women have been waiting it out with their children in their home countries while their husbands have been in this country for two, three, four years working. Theyre working in construction. Theyre working in agriculture. Theyre working in meat packing plants. These are people already working in our community and their families, the rest of their families are fleeing violence. We need to look at this picture honestly, ali. We have to understand our role. We have to understand the root factors. This idea if you close loopholes suddenly migrants will stop coming. Thats a complete denial of whats really happening. It serves no one well. So, im looking forward to continuing the work that we have been doing in the house, trying to address these root causes and trying to find Real Solutions instead of what the administration has been doing, which, by the way, has been taking Steven Millers lead. I hope that the president sees that the advice he keeps getting from Stephen Miller ends up creating worse situations, bigbbig bigger problems, more chaos. Just like they rid themselves of Kirstjen Nielsen. But we will come forward with Real Solutions and real ideas. No reason we should be treating people inhumanity and we dont treat it with compassion. Congresswoman escobar, thank you for joining us. Thank you. Three Service Members have been killed outside an attack in bagram airbase. Courtney has been following this and has the latest from the pentagon. Hi, ali. An attack just outside of bagram air base. Which is just outside of kabul. This is being described as a catastrophic vehicle born ied. Three american troops were also injured in this attack. We dont know yet very much about who is behind it other than the taliban have released a statement claiming responsibility. They say it was a vehicle attack, but theyre claiming that the number of killed and wounded was higher, as is often the case in these sorts of incidents, ali. Courtney, is this a har binger of something more seriously. Taliban claiming responsibility for this attack. Its arer not the kind of thing. Even as i read that breaking news. Not the kind of thing we commonly hear about. What is the context around this . If you look at this in the bigger context. Afghanistan, there is still a war going on there. The timing of this is very critical, though. Because it comes when the u. S. Special envoy is in the midst of negotiations with the taliban. Hes trying to bring the Afghan Government into these negotiations to reach some sort of a peace settlement after nearly two decades at war, ali. But people forget. The u. S. Military and the coalition and the Afghan Military are still engaged in a very active war there. Both with the taliban and now with this huge threat from isis up in the east, ali. Courtney, thank you so much. National security and military reporter joining us from the pentagon. More breaking news. Acerous Felicity Huffman is pleading guilty.

Felicity huffman and several other parents are pleading guilty for their part in the largescale College Admission cheating scandal. One of the 50 people in what they call the biggest College Admission scam ever prosecuted and the investigation is ongoing. The actress released a statement saying, quote, i am in full acceptance of my guilt and with deep regret and shame over what i have done. I accept full responsibility for my actions and will accept the consequences that stem from those actions. Joining me now is miguel who has been following this closely. Miguel, some question about how this was going to go given the evidence that prosecutors seemed to have on her and others. They had a strong case and many people were expecting a plea deal. 13 parents have entered a plea deal. I want to read you more of the statement released. She goes on to say after what you have read, i am ashamed of the pain i have caused my daughter, my family, my friends, my colleagues and the educational community. I want to apologize to them and especially i want to apologize to the students who worked hard every day to get into college and to their parents who make tremendous sacrifices to support their children and do so honestly. She went on to say my daughter knew absolutely nothing about my actions and, in my misguided and profoundly wrong way, i have betrayed her. This transgression towards her and the public, i will carry the rest of my life. My desire to help my daughter is no excuse to break the law or engage in dishonesty. There you have it. Felicity huffman taking full accountability for the crime she says she committed to get her daughter into usc or one of these eight elite universities across the country. Huffman is accused of paying 15,000 to have a proctor correct answers on her daughters s. A. T. Exam. Therefore, bringing up her daughters s. A. T. Score so she could get into one of the elite eight universities. One of 13 other parent who have taken a plea deal. This may be the beginning of what we see, several more plea deals in the works. In a couple cases in one case at yale somebodys admission was rescinded after theyert s start studying there. In the case of Felicity Huffman, william h. Macy was not charged. He was caught discussing it with singer but they didnt feel it was appropriate to charge william h. Macy so Felicity Huffman alone was charged in the iscase. Several parents have been accused of this crime. Lori loughlin and her husband who is a fashion director have not entered a plea. There is no word yet, ali, on what other parent may do who are still involved in this case as you know. 50 parents, 50 people were charged and arrested in this case and the alleged ring leader, william singer, said he helped upwards of 700 families. Prosecutors told nbc news that there certainly could be more arrests and more charges in the coming days. Miguel, thank you for your reporting on that. The Trump Administration is taking an unprecedented step as part of itseft. A Foreign Terrorist Organization. The United States has already sanctioned dozens of people and entities associated with the elite branch of irans armed forces but never the whole organization. This is the first time that the United States has designated a part of another government. Were doing it because the Iranian Regime use of terrorism state craft makes it fundamentally different from any other government. This historic step the leading state sponsor of terror and the financial means to spread misery and death around the world. Israeli Prime Minister benjamin netanyahu, thanked President Trump in a tweet saying, once again, you are keeping the world safe from iran, aggression and terrorism. Designating u. S. Military forces as a terrorist organization. I want to take a look at why the u. S. Would target the Islamic Revolutionary guard corps. Set up after the Islamic Revolution in 1979 to defend the new government. Commands its own air, land and naval units and it also controls irans Ballistic Missiles and other Nuclear Programs. The force has also been a network of domestic paramilitaries known as the basij and a special Operation Unit known as the quds force. And this will become relevant in just a minute. The irgc have 125,000 members and answers directly to irans supreme leader. The oerlrganization got involven reconstruction efforts after the war of the 1980s and since expanded its economic interests to include a vast network of businesses which are said to include oil and gas projects, banking, shipping and telecommunications. They are a big part of the iranian economy. The u. S. Estimates the irgc may actually have control or significant influence over as much as half of the iranian economy. I want to have a little more of this conversation. I want to bring in david s. Cohen. Hes a former Deputy Director of the cia and former under secretary of treasury for terrorism and financial intelligence. He was one of the architects of the sanctions that pushed iran into making a deal to curb its Nuclear Program. He currently leads the financial and Business Integrity group at the law firm. Thanks for beelg wiing with us. Thanks, a li. You understood the value of sanctions particularly with respect to iran. Where does this stand where you feel . The sanctions i put in place were very effective. They were designed to achieve an objective and generate leverage for a negotiation with regards to Irans Nuclear program. The irgc was a major target of ours. Contrary to what secretary pompeo just said has been designated multiple times. As we sit here today before this fto designation, the Forei
