As america is marking the anniversary of a turning point in the civil rights movement. It happened at the university of oklahoma in norman where members of a fraternity recorded a racist chant, which, of course went online. Today the fraternity was shut down and the University President said he wants the students in the video to leave and he offered to pay their bus fare. Jericka duncan is in norman, oklahoma. Reporter this is the video that did so much damage in only nine seconds. Reporter the clip was posted on a web site sunday night. We dont know when or where it was shot. We dont know the identities of the students. The video makes light of lynchings and barring blacks from Sigma Alpha Epsilon or s. A. E. Before sunday night was ovher, the National Fraternity disowned the o. U. Chapter. Brandon weghorst is the national spokesman. We are apologetic not only to the individuals who are offended by the video, but to our own members, who are from different backgrounds. Because they should never see a video like that. They should never be subjected to that kind of hateful message. Reporter the frat house was shut down by the university and members were ordered to move out by tuesday night. Early this Morning University of oklahoma president david boren joined students who gathered to protest. These people have acted in a way that is absolutely reprehensible and disgraceful. We cannot put up with it. Reporter isaac hill is the president of the black Students Association on campus. He says hes disappointed but not surprised. I have been amazed to see how o. U. Has come together to say, not on our campus. We will not accept this and we will not sit idly by. Reporter with 15,000 members nationwide, s. A. E. Is First Fraternity in the antebellum south.

Today hundreds protested inside the Wisconsin State Capitol building after an unarmed black teenager was shot to death by a White Madison police officer. The police say the teen was assaulting the officer but still the police chief called the death a tragedy and asked his family for forgiveness. Dean reynolds is in madison. Black lives matter black lives matter reporter increasingly large crowds of demonstrators marched on the Wisconsin Statehouse this afternoon and filled its 98 yearold rotunda with a familiar chant. Hands up. Dont shoot. Hands up. Dont shoot. Reporter 19yearold Tony Robinson was shot dead by officer matt kenny, who trailed him to his house. 19 years of age. Name is Tony Robinson. Apparently tony hit one of his friends. No weapon seen. Reporter police say the shooting took place when kenny responding to 911 calls about robinson, was attacked by him in the entryway of the home. Shots fired, shots fired. All lives matter. Thats right. Reporter while the demonstrations have been peaceful, emotions here are raw. This Weekend Police chief michael cobalt visited robinsons family. You went out of your way to be sensitive to the people who would be most disappointed by what happened. But that goes to a core value. I believe life is sacred, so why wouldnt you express remorse at the loss of a young life. That seems only natural. Reporter today the chief posted on the police web site reconciliation cannot begin without my stating i am sorry, and i dont think i can say this enough. I am sorry. Today his family gathered just a few feet away from where robinson died. His uncle turin carter spoke for the grieving parents. This is a bigger issue than tony. This highlights a universal problem with Law Enforcement and how its procedures have been carried out, especially in light of whats happened over the summertime. Reporter his uncle said Tony Robinson was no saint, perhaps a reference to his conviction for armed robbery. For now, scott, the state department of justice in madison is investigating the case and the federal department of justice in washington is monitoring it closely. Pelley Dean Reynolds for us tonight. Dean, thank you. At the Boston Marathon bombing trial today, we saw for the first time the video that led police to the tsarnaev brothers. The defense has admitted that Dzhokhar Tsarnaev and his late brother planted the bombs. His lawyers are now trying to save him from the death penalty. Don dahler is covering at the courthouse. Reporter f. B. I. Forensics expert anthony amos showed the court video compilations geared from the scene. Dzhokhar and Tamerlan Tsarnaev can be seen wearing backpacks. The younger brother appeared to set his backpack down feet away if the youngest victim, eight yearold martin richard. He made a phone call. Records show he spoke to Tamerlan Tsarnaev for 19 seconds. Just after the phone call ended, first bomb went off. Everyone else turned to look but dzhokhar headed in the other direction. 12 seconds later, the second bomb exploded right where he had been standing. Video never made public until now shows the younger tsarnaev running away. If the Video Evidence put the tsarnaev brothers at the scene the mornings testimony put the jury there. Nurse Jessica Kensky was a newlywed watching the race with her husband patrick. When the bomb exploded, she said it felt like she was shot into the air on a rocket. Theres smoke. Theres blood, she said. I was most focused on my husband right next to me. His foot was detached. Jessica evenly lost both her legs. Fireman Matthew Patterson ran up to seven year old jane richard. She was amputated above the knee. There was barely enough left to apply a tourniquet. Prosecutors showed video 30 minutes after the bombings of Dzhokhar Tsarnaev buying and then exchanging a bottle of milk at a nearby Grocery Store and going to a gym for a workout the next day. Prosecutors also presented a number of tweets from Dzhokhar Tsarnaevs two twitters accounts, including some from months before the bombing in which he talked about the glory of martyrdom and expressed his expectation that he would die young. Scott, there was also a tweet posted a day after the bombings by tsarnaev in which he said he was a stressfree kind of guy. Pelley don dahler reporting. Don, thanks very much. Another video today captured the moment an amtrak train slammed enter a tractortrailer in north carolina. The truck was stuck on the tracks. The driver jumped and hes all right. But at least 40 passengers were hurt when the locomotive flipped and the first two cars left the tracks. There are injuries, but theyre not believed to be life threatening. In washington, it used to be said that politics stops at the waters edge, but today in a highly unusual move, 47 republican senators warned the leaders of iran against president obamas proposal to limit the Iranian Nuclear program. The administration has been negotiating this for months and a deadline is three weeks away. Heres nancy cordes. Reporter the open letter to iranian leaders was one part civics lesson, one part warning shot. It has come to our attention republicans wrote, that you may not fully understand our constitutional system. Congress, they explained, must sign off on any deal secretary of state john kerry strikes with iran over its Nuclear Program. Anything not approved by congress is a mere executive agreement and could be revoked by the next president with a stroke of a pen. I have never seen anything like it. Reporter Senate Democrats accuse republicans of undermining delicate negotiations. Democratic leader harry reid. I disagreed with president bush so very much to what he was doing to our country, but i would never ever consider anything even close to this. Reporter irans foreign minister called the letter a propaganda ploy and says it seems that the authors do not understand International Law or the nuances of their own constitution. The letter was written by tom cotton, a freshman senator from arkansas. It simply tells the leaders of iran that if congress doesnt approve a deal, Congress Wont accept a deal. The only thing unprecedented is an american president negotiating a Nuclear Agreement with the worlds leading state sponsor of terrorism without congressional approval. Reporter but the president insists he does not need congress to sign off. I think its somewhat ironic to see some members of congress wanting to make common cause with the hardliners in iran. Its an unusual coalition. Reporter those hardliners in iran are one reason that the white house only puts the chances that a deal will be struck at 50 50 at best. What worries republicans, scott, are reports that any deal would sunset after ten years, giving iranians the chance to restart their Nuclear Program where they left off. Pelley nancy, thank you very much. Americas top general flew to baghdad today to see how the iraqis are doing in the fight against isis. He did not sound impressed. Iraqi forces are attempting to retake the city of tikrit, but this hasnt been a breakthrough. Holly williams is in baghdad. Reporter even with thousands of iraqi fighters on the outskirts of tikrit, progress against isis is slow. Iraqi forces claim they have cut supply routes to the militants yet isis is still in control of the city. In baghdad today, the chairman of the u. S. Joint chiefs of staff, general martin dempsey, urged patience in the fight against isis. But on board a french Aircraft Carrier in the persian gulf yesterday, dempsey voiced his frustration with iraqi forces. Weve got trainers and advisers that are waiting for some of the iraqi units to show up, he said. And when theyve shown up handful of them, theyve shown up under strength and sometimes without the proper equipment. Raad saleh ateia and his wife quaraish are desperate for any sign of progress in tikrit. They fled their home in the city just three days after isis captured it in june. Armed men from isis took our son omar away, quaraish told us. I chased after the car and i was crying because i couldnt keep up. Raad told us isis interrogated 20yearold omar and accused him of drinking alcohol. The militants later released him but omars still too frightened of isis to appear on camera. Do you think that iraq will ever be free of isis . God willing, quaraish told us. We want everyone to go home to their families. Pelley holly, so far in this fight for the city of tikrit the u. S. Has been on the sidelines. Did general dempsey say anything about the level of u. S. Involvement in iraq . Reporter well, scott general dempsey says he saw no need for any more u. S. Military advisers in iraq. They are already more than 2,500 of them on the ground here. He also made it clear that a dramatic escalation in american led air strikes or carpet bombing iraq, as he described it, would risk many, many more civilian casualties. Pelley Holly Williams reporting for us tonight from baghdad. Holly, thank you.

One source is telling us that shes considering a news conference. Conducting official business by private email would appear to violate a 2009 law designed to protect public records.

President , when did you first learn that Hillary Clinton used an email system outside the u. S. Government for official business while she was secretary of state .

Obama did know that clinton had a private account because he sent emails there for four years.

Pelley recently clinton turned over 55,000 pages of e mails to the state department. Shes tweeted that she hopes theyll be released to the public. Theres a murder mystery at a prestigious dog show.

Pelley it was 50 years ago this weekend that first u. S. Troops went ashore in south vietnam. By then u. S. Airmen had been bombing the north for seven months, and those who were taken prisoner entered a living hell that would last the rest of the war. All these years later, survivors shared their stories with david martin. American pilots shot down and captured by north vietnam.

I broke my back on landing. Reporter as the bombing continued, hundreds of american pilots were shot down and captured. Some died in captivity.

You can imagine how painful that must be after hours and hours. This went on for about two weeks. Reporter the only way to stop the pain was to tell the north vietnamese something more than name, rank and serial number. So the first time you broke.
