Plus the Baltimore Police commissioner surprised about the charges against six of his officers in the death of freddie gray. Now another surprise. One of those officers filing his own legal challenge. Lets talk in the cnn newsroom. Good morning. Im carol costello. Thank you so much for joining me. Lets start in baltimore where mayor stephanie rawlingsblake is about to announce a new partnership between her city and the u. S. Department of justice. It comes a day after a visit by the new loreattorney general. Well bring this News Conference to you live when it happens. Also in the news this morning, a jaw dropping new report shows that the copilot who deliberately crashed a germanwings jet into the alps made a practice run with passengers onboard. He did it five times on an earlier flight the same day of the crash. The copilot a germanwings on march 24th, investigators say he purposely flew the plane into the french applelps while the copilot wascopilot was locked out of the cockpit. Reporter chilling details that emerged from accident investigators saying that he had gone through the scenario on the outbound leg of this flight. He was flying at 7 30 in the morning and the scenario was identical to that of the fatal crash. The pilot stepped out of the cockpit. Lubitz was left alone. Instead of dialing in 35,000 feet into the autopilot, he dialed in 100 feet. Quickly dialed it back to the altitude of 35,000 feet and then seconds later the air Traffic Controllers ordered him to descend to 21,000 feet and he dialed in 100 feet instead of 21,000 feet. And before the pilot could get back into the cabin, he put it to assigned altitude of 21 this feet. The pilot probably had no knowledge of any of this. When you dial in these descents its a controlled descent. Its not like the nose suddenly drops. It was a controlled descent and air Traffic Controllers ordered it. He had gone through this scenario before and it just adds a whole new dynamic to the idea that he had taken the plane down on that next flight over the alps. It was a very well planned incident. Jim, thank you. In texas, investigators believe at least one of the gunmen in sundays attack had contact online with isis operatives. Elton simpson on the right exchanged tweets with two isis members, one american and the other british. And while there are doubts that isis plotted the attack one u. S. Official says the terror group certainly provided more than just inspiration. Now the grieving mother of the gunman killed with him accuses simpson of trying to turn her son into a killer. Ed lavandera following all of the latest twists for us. Good morning. As you mentioned, a lot of focus really on Elton Simpson the 30yearold gunman who drove here to garland on sunday night along with his roommate from phoenix, arizona. A lot of focus on simpson. But the mother tells a local affiliate that Elton Simpson must have just brainwashed him. Shes talking about her son. Im not saying hes that gullible but to be convinced to do Something Like this is beyond me. Investigators trying to piece together the movements and conversations that these two men had over the last few weeks. Two Law Enforcement officials tell cnn that simpson was in touch with a jihadi overseas an american who is believed to have moved to somali back in 2008 and alerted these men about this cartoon contest that was going to be taking place in garland on this past sunday. So this talk about whether or not they were inspired by isis or just the length and what extent of their communications with isis sympathizers around the world and this is really pointing to the issue that many Law Enforcement officials here in the United States are the most concerned about is this kind of inspiration and tracking these kinds of people here in the United States that might not be getting direct training but might be inspired by that. Carol . I understand that family members are speaking out this morning as well. They have been. There have been several family members who they consistently have been saying they did not notice any of these kinds of radicalization in their relatives and in these two men. There were no outward signs that pointed to them being radicalized in this way. All right. Ed lavandera reporting live for us from dallas. Thanks so much. In the meantime the u. S. Is trying to hunt down four isis terrorists. Its now offering a bounty up to 20 million. Terrorists include a spokesman for isis and the chief in charge of the groups suicide bombers. Lets talk about that bounty and if those bounties will lead to arrests. Lets talk about this with christopher. Welcome. A pleasure carol. Is it a good idea, these bount risies bounties . I dont think theyll do any good. One of the things isis has done is to create a territory that it controls completely. So its not like in the past where we had terrorists with bounties on their heads moving around in pakistan or other place places where they may be fingered and apprehended. Theyre operating in secure territory. If i remember correctly, there was a 25 million bounty on Osama Bin Ladens head and that was never paid out because they had inside sources and thats the way they tracked Osama Bin Laden down. Its not like people think im going to get rich and turn in Osama Bin Laden or abu bakr al baghdadi. Theres a 10 million reward on his head by the way. These people were talking about recently renounced are in the 7 million, 5 million, 3 million category. Nobody wants to risk being hunted down forever by a bunch of jihadists if they turn these guys in and they have to be close to them to turn them in. I want to focus now on Elton Simpson because this is its just so hard to believe that this kind of young man could be radicalized. He grew up in a christian home. I know his basketball dreams ended with an injury. He did have a job. He seemed to have friends. He had a Good Relationship with his family. So how could such a man become radicalized just by reading stuff on social media . It isnt just reading stuff on social media. I think that we have to recognize that the socalled Islamic State has one of the most sophisticated social Media Operations and internet operations weve ever seen. Its not about hacking. Its about seducing in fact. And they use every means at their disposal. Ive been looking recently for instance at the way they pick up the imagery from video games, from war games, things like call of duty in order to lure young men who are playing these games sort of into the psychology of fighting a holy war. I suspect that kind of thing is what happened with simpson. I think as they study what he was doing, i think it will be important to look not only at who he was sending emails to or who he was chatting with or who he was tweeting but what sort of games he was playing. All right. Christopher dickey, thank you for your insight. I appreciate it. Still to come Hillary Clinton is taking a stand on immigration. How she is slamming her republican rivals next.

Justice department after a visit by the new attorney general, Loretta Lynch. Six officers were charged in the death of freddie gray. They just tested the microphones. We expect this News Conference to start any minute and when it does shs does well bring you back to baltimore live. Hillary clinton takes a stand on immigration. She called for comprehensive Immigration Reform while slamming her republican rivals. Make no mistakes today not a single republican candidate announced or potential is clearly and consistently supporting a path to citizenship. Not one. When they talk about legal status that is code for secondclass status. Dana bash and jeff zeleny are covering all things clinton campaign. Dana i want to start with you. How are republicans reacting to Hillary Clintons plan . You know i actually expected the very very large number of republican candidates to kind of come back at her quickly and hit her on a whole host of issues relating to her statement on immigration. It hasnt happened yet in that mass responding kind of way. There was one republican pretty new republican candidate Carly Fiorina speaking to erin burnett last night who did respond. Listen to this. Unfortunately i think shes pandering. I think we need to start with some basics. We need to secure the border. She accused her of pandering. The one thing i actually have heard, carol, from republican aides to candidates across the board this morning is that they actually saw what Hillary Clinton did as trying to pick a fight with republicans. Remember she has been taking income from a dozen republicans constantly for months and months and months on a whole host of issues. And in this particular case some of them felt like its time for her to pick a fight with them. So far we havent seen so much of a response. One other thing i want to say is when it comes to the substance of what she proposed, certainly when she talked about a path to citizenship, most republican candidates dont support that. One Lindsey Graham wholeheartedly does. Once republicans begin to respond, the biggest thing youre likely to hear isnt on the cammest estamnesty front but more on the idea that shes going to be more of an imperial president than even barack obama. Thats something that gets huge applause lines from Republican Voters when you talk about the president. Now that Hillary Clinton has said she would extend the executive order that the president did on immigration, that gives republicans even more meat on that bone to hit Hillary Clinton on the same thing. Interesting. Okay. In the meantime former u. S. President bill clinton is defending his wife overseas. Jeff what can you say about that . He sure is carol. Hes at a Clinton Global Initiative in morocco and spoke with our Christiane Amanpour and he pushed back hard saying theres no evidence to any allegations of wrongdoing or undo influence that his wife the former secretary of state, had while she was in office thats linked to any of those foreign donors. Lets take a listen to what he said. We had a policy when she was secretary of state that we would only continue accepting money from people that were already giving us money. And i tried to recreate that policy as nearly as i can now during the campaign. Even the guy that wrote the book apparently had to admit under questioning that he didnt have a shred of evidence for this. He just shortort of thought he would throw it out there and see if it would fly. It wont fly. Hes not going to have the last word on this. This is going to be an issue in this debate. Weve not heard from Hillary Clinton herself on some of these specific allegations but the campaign is trying to pivot immediately. Shes why she was talking about immigration and why she was talking about substantive policy as dana was saying. So Many Democrats have urged her to get on with her campaign and speak about what she wants to do. Thats what shes trying to do. Dana bash jeff zeleny thank you so much. I think i see the mayor of baltimore walking to the podium right now. Lets go to baltimore and hear what stephanie rawlingsblake has to say. Before i take a few of your questions, i would like to make some brief remarks regarding our ongoing efforts to reform the Baltimore CityPolice Department. Throughout my administration we have taken a number of steps to change the culture and the practices of the Baltimore Police department. Ive worked with commissioner to build Greater Trust between the police and the community. Our efforts have included the development and implementation of recommendations from baltimores first ever Strategic Plan for reform. Dismantling the police unit known as Violent Crimes impact section, which had been the target of repeated citizen complaints for harassment and Excessive Force. A series of Public Safety town halls across baltimore in nine Police Districts where i solicited Community Input later incorporated into new ethics and situational training reforms. The recruitment of the department of justice cops program last october to launch a collaborative process to further enhance reforms. The adoption of new Police Schedule that puts more officers on the streets so that they can build deeper relationships with the citizens that they protect. Our department will have body cameras before the years end. Meanwhile, ive also fought before the General Assembly in annapolis to make substantive changes to the state Law Enforcement officers bill of rights. Those reforms would have assisted in the disciplinary process for those officers who engage in misconduct. While our legislative efforts did not win approval in 2015 i am optimistic that we will have greater success in 2016. We have seen results from these efforts. In 2014 citizens complaints allegeingeing Excessive Force were down 46 . Police discourtesy complaints were down 53 . Notices of lawsuits alleging Police Misconduct are down dramatically in the last three years and our Police Department reports greater success punishing officers found guilty of misconduct in an administrative process. Despite this progress we all know that baltimore continues to have a fractured relationship between the police and the community. Recent events continue to demonstrate the need to press forward with these reforms. We have to get it right. Failure is not an option. In order to achieve the kind of sustainable and significant reform that we want to see, that i want to see, that the citizens want to see in baltimore, i am requesting the department of justice conduct an investigation into the Baltimore CityPolice Department. The department of justice has employed these investigations in communities across our nation to reform serious patterns and practices of Excessive Force, bias policing and other unconstitutional practices by Law Enforcement. Such an investigation is essential if we are going to build on the foundation of reforms that we have instituted over the past few years. Im asking the department of justice to investigate if our Police Department has engaged in a pattern or practice of stops, searches or arrests that violate the fourth amendment. I am asking that they investigate what systematic changes or systemic challenges exist within our Police Department that can contribute to Excessive Force and discriminatory policing. At the end of this process i will hold those accountable if change is not made. We cannot be timid in addressing this problem. I am a mayor that does not shy away from our citys big challenges. At no other time in our citys recent history has any administration brought this level of resources to the table to change our Police Department. While the past few days have been some
