Lets get to the top story. New fallout over a racist chant by members at the university of oklahoma. There allegations this was not an isolated incident. Gabe gutierrez is at the campus in Norman Oklahoma this morning. Good morning. Reporter officials here are not mincing words and are sickened by the video and they shut down the fraternity and look at whether they violated the civil rights act. This morning members of Sigma Alpha Epsilon are packing up given until the end of the day to move out of the house. The chapter suspended in disgrace. The university of oklaho. Now new allegations that this behavior is nothing new. I would definitely say its not isolated. We talked to an ou senior who asked that we not use her name or show her face because she didnt want to be associated. She was invited to a date party two years ago and heard the same chant on the bus. I was disgusted. The National Headquarters responded by email. We learned that others came forth to say they heard the chantd before which is deeply disturbing. Our Administration Never heard this inappropriate chant. They are investigating. They said they were the second and the last africanamerican to pledge at oklahoma 14 years ago. He said he now has a hard time looking himself in the mirror after seeing the video. We will always be family but this part is difficult. The top ranked Football Team came together to pray and protest. The University President had sharp words for the students in the video. As they packed their bags i hope they think long and hard about what they have done. Sigma alpha epsilon is one of the nationals largest fraternity with 50,000 current members and 200,000 living alumni. They are looking at all options including expulsion. Breaking overnight, the u. S. Ambassador to south korea released from the hospital nearly a week after he was brutally attacked by a man with a knife. He spoke about the incident and his recovery. Peter alexander has the latest. Reporter good morning. The ambassador looked remarkably well considering the attack a week ago. He always felt very, very safe d insisted this situation had only strengthened his affection and the bond between our two countries. I feel pretty darn good all things considered. It was a scary incident. I have a little rehab left to do on the arm and the face feels really good but thanks to the great medical professionals, i feel pretty darn good. One week ago he was viciously attacked while at a breakfast in seoul suffering a fourinch slash to his face. E aftermath caught on camera. I need an ambulance. His attacker was tackled to the ground and taken away while loudly protesting the military exercises. He underwent three hours of surgery, receiving 80 stitches. An attack that raised questions over how the suspect was able to get so close to a high ranking u. S. Official. He was assigned one unarmed body guard. Today he was grateful. I want to express profound gratitude to koreans and americans who bravely and selflessly responded to the scene. He is looking forward to get back on the job. I am eager to get back to working on the strong and dynamic relationship. I will do so with more purpose and enthusiasm. It would be premature to talk about the attack itself. He needs to talk to Law Enforcement first and whether security needed to be tightened. The state support has to take a look at tactics, techniques and procedures. The process is under way. I am surprised how well he speaks and he is recovering beautifully. He has been hugging his wife and new baby. Crash investigators are looking into the third major next a few weeks. An amtrak train carrying over 200 passengers plowed into a truck on the tracks. Tom costello is at the scene this morning. Several dozen people were injured. About three remain hospitalized. The train has been picked up off the tracks. This is whats left of the truck carrying this modular housing unit that was wrapped in blue. It was trying to make a turn. The crash captured on video. From her car near the tracks leslie captured on video the moment of the trains impact. An amtrak passenger train plowing into a tractortrailer that was stuck on the tracks. Oh, my god the crash was so horrible. The worst thing i have ever seen. They describe a sudden crush and impact. My chair, i went flying forward into my tray. Gave my heart a little pounding. There was a lady down on the ground. The lead car seemed lying on its side and the car behind seemed pushed into the woods. They were taken to the hospital with injuries but none was lifethreatening. They were traveling for charlotte to new york and struck a loaded tractortrailer stuck on the tracks while maneuvering to make a left turn. The length of the trailer was more difficult and of course the train then approached and stayed down where the arms came down as a result. The vehicle was stuck. Nothing the driver can do. This derailment is the most recent in the collisions. A train struck an suv, killing six people and just three weeks later, a metro link train in Southern California collided with the truck stuck on the tracks. The engineer died from his injuries. Here in North Carolina a frightening moment she will never forget. I try not to look at the video too much because it breaks my heart. It could have been me or somebody in my family. Oh, my god reporter state troopers were trying to help that driver maneuver his truck off of the track when is the crash occurred. Rail authorities will take overlooking into what happened. Back to you. Tom costello, thank you. The white house is acknowledging that president obama did Exchange Emails with Hillary Clinton on her private address. The course is growing louder for her to address the scandal. Andrea mitchell is here with the latest on that. Good morning to you. Good morning. Hillary clinton is likely to hold a News Conference in the next few days after intense pressure to clear up the email controversy. Under fire for the second straight week Hillary Clinton is not saying why she set up the private email system as secretary of state. Will you explain the email . She may be reluctant because of april 1994. She held a white house News Conference about an arkansas landing that led to more investigations. She wants todays focus to be womens rights in a speech at the un as she hints as making history as potentially the first woman u. S. President. When women and girls have the opportunity to participate, we can lift up not just ourselves, but our Families Communities and even our countries. The controversy was not part of a game plan and the white house acknowledged monday president obama did Exchange Emails with clinton when she was secretary of state and said he didnt know she didnt also have a government account. The president was not aware that this was a personal email server and this was the email address she was using exclusively for all her business. The long time defenders are firing back. This is not going to change anything but it gives people a reason to get out of breath about stuff. 86 of democratic primary voters in the wall street journal poll support her. Analysts say the email issue has shown vulnerabilities. It brings added scrutiny to remind people that she is a complicated candidate. When she does hold the News Conference much anticipated advisers say her explanation will be simple. In part with her complicated travel schedule it was more convenient and it was not strictly prohibited under the rules. Do we have anyone behind in washington. Chuck todd has a new poll. Lets start with the hillary issue. It seemed for the last seven days or so her approach was not to say anything beyond one tweet. What changed the calculus now that she is going to . Democrats are struggling to defend this. The democrats are struggling to do this and she realizes the longer she goes the more she has to speak out. What she needs to say is its more than explain ing why she did it and apparently she is going to say the server was more secure. I think she needs to announce something actionable like turn the server over to the state and let them have it. I think its going to have to be more than an explanation. Does it have staying power in terms of 2016 or a distant memory. Its Congressional Republicans have every bit of motivation to keep investigating. Without t they wouldnt have discovered this. Lets talk about the poll. You posed the question what do people want a greater change or experienced candidate . We asked this question for three cycles. 59 said they wanted a candidate for change rather than someone test and experienced. Whats amazing is its higher than 2008. Thats going to be bad news for hillary and jeb bush. Who do you think they represents change . Hillary clinton or jeb bush . Neither one. Both represent a politics of the past. It tells me Hillary Clinton needs jeb bush as the republican nominee. That helps her more than she realizes. It is day four of the trial of the admitted boston bomber. Prosecutors revealed powerful Surveillance Video of the attack and the aftermath. Heres pete williams. Prosecutors say these videos never before shown publicly were gathered from dozens of cameras. They show him with his older brother walkings along the marathon route with am bos in their backpacks. A key piece of evidence is surveillance and this spot on boylston street.

Thats him circle standing in the crowd after he is there a while, his backpack can be seen resting on the sidewalk. He makes a quick phone call to his brother and walks away and then comes the searing white hawk flash of the bomb. Witness after witness described what is described as chaos. They jumped over barriers and jumped towards the blast site to help the injured, this camera captured the image of him running away from the scene. Barely a half hour later with victims in the hospital facing amputation he was calmly shopping for milk. A sign he thought what he did was good and right and he considered himself a soldier in a holy war against americans. The next night, another surveillance camera showed him and a friend checking into a campus gym for a work out. Pete williams nbc news boston. We will continue to follow that one.
