It was 62 years ago this week thathe Supreme Court outlawed segregation in public schools. But it never went away. A study ordered by Congress Found the percentage of highpoverty schools with mostly black or hispanic students has more than doubled since 2000. Michelle miller went to a district in the deep south thats been ordered to desegregate. Reporter the mississippi delta town of cleveland has been grappling with its segregated past for 50 years, and now its time has run out. In a ruling, a federal judge ordered the district to merge two high schools and two middle schools, saying the delay in desegregation has deprived generations of students of the constitutionally guaranteed education. Jamie jacks, the School Districts attorney, says the order doesnt give the full picture. We have kids learning side by side each other of different races. If you travel to our surrounding communities here, youll see that doesnt exist. But we have it here. Reporter the problem centers around clevelands two high schools.

The side effects are hitting me a little bit harder than they did last year. Reporter her cancer had started on the right side of the colon, a location that can be more deadly. Todays study of patients with advanced colon cancer found those with tumors on the right side survived an average of 19 months compared to 33 months for those with tumors on the left side. Dr. Richard goldberg is an oncologist with the Ohio State University comprehensive Cancer Center and is a coauthor of the study. This data shows that we ought to be thinking differently about patients depending on where their cancer arose. Reporter patients with cancer on the right side tend to have fewer early symptoms are often diagnosed later. One reason benign rightsided polyps can be harder to spot during a colonoscopy. Many polyps are obvious, like this one that looks like a mushroom. But polyps on the right side tend to be flat, increasing the odds of being missed and eventually turning into cancer. When i go to clinic next time, im going to be thinking, right side, left side. Different treatment. Reporter todays study suggested certain types of chemotherapy may be more effective with colon cancer starting on the right side than the left. That may be especially relevant for africanamericans who are more likely than whites to have rightsided colon cancer and less likely to survive. Thanks, jon.

Grow apple trees and honeybees and thats the overnight news for this thursday. For some of you the news continues. For others check back with us a little later for the morning news and cbs this morning. From the Broadcast Center in new york city, im anthony mason. Announcer this is the cbs overnight news. Welcome to the overnight news. While the Republican Party is slowly coming together behind the presumptive president ial nominee donald trump the democrats continue to battle amongst themselves. Hillary clinton and Bernie Sanders split the primaries tuesday. Sanders winning oregon. Clinton taking kentucky by less than a point. Their fight for delegates is becoming dirty. Nancy cordes reports. Reporter this is striking because the party has been treating sanders with kid gloves lately, wary of alienating his millions of supporters. But those gloves have come off after an ugly incident in nevada. They say his campaign could have prevented. And theyre worried there could be more to come. I am getting to like the coast [ cheers and applause ] reporter as sanders reveled in his oregon win, the clinton camp celebrate aid photo finish in kentucky, enough to halt a sanders winning streak. Thanks to everyone who turned out, clinton tweeted. We are always stronger united. But that unity is being tested by a growing dispute over nevadas chaotic Democratic Convention. It was disrupted for hours this weekend by sanders supporters who were angry about the delegate rules which they felt favored clinton. In a blistering letter monday state Party Officials accused the Sanders Campaign of inciting disruption and, yes, violence by an irrational minority. They started rushing the stage. Reporter roberta lang is the state party chair. They stood in front of me and were yelling vile things at me, calling me names. We had chairs thrown at the stage. Reporter and the abuse didnt end there. Officials say sanders supporters posted her cell phone and home address online. Shes gotten hundreds of i would pack your bags right now because the [ bleep ] storm youve ensued is coming. Reporter on tuesday the senates democratic leader who represents nevada says sanders needs to vocally condemn those tactics. Im hopeful and very confident senator sanders will dot right thing. Reporter but a defiant sanders faulted nevadas Party Leadership saying it used its power to prevent a fair and transparent process. Officials quickly called that a lie. I say to the leadership of the democratic party, open the doors, let the people in reporter the chair of the Democratic NationalCommittee Said last night sanders is adding fuel to the fire when he could be putting the fire out. Very rare to hear her criticize one of her candidates. He picked up just four more delegates than clinton, who now leads him by about 3 million votes. For the republicans donald thump continues to march through essentially unopposed. Trump needs fewer than 80 delegates to clinch the nomination. Polls show hes not doing well with woman voters. But one powerful woman is standing up for him. His daughter, ivanka. She sat down with norah odonnell. Im going to ask you about the new york times. They ran a frontpage article this sunday about your father and the treatment of women. Did you read it . I did. And i found it to be pretty disturbing based on the facts as i know them. And obviously i very much know them, both in the capacity as a daughter and in the capacity as an executive whos worked alongside of him at this company for over a decade. So i was bothered by it. But its largely been discredited since. Most of the time when stories are inaccurate theyre not discredited. And i will be frustrated by that. But in this case i think they went so far, they had such a torong thesis and created facts and i think that narrative has been playing out now, and theres backlash in that regard. I do want to read you from part of the article. It says many of the women interviewed revealed unwelcome romantic advances, unending commentary on the female form, a shrewd reliance on ambitious women and unsettling workplace conduct. Is there unending commentary on the female form . No. No. And again, this is an article that is widely being discredited. The lead person who was interviewed for the story and that the story opens up with is all over the news yesterday saying that they manipulated what she was saying. I dont find it that meaningful to comment on this particular story because i think the facts are starting to speak for themselves. But you have worked so closely with your dad. Theres another woman who is quoted in the article that says that donald trump groped her at a you know, at a meeting, at a business meeting. Look, im not in every interactn but hes not a groper. Its not who he is. And ive known my father obviously my whole life. And he has total respect for women. He was promoting women in development and construction at a time when it was unheard of. There was no trend toward equality in the real estate and Construction Industry back in the 1980s. And he was doing it because he believes ultimately in merit. Hes running against a woman. And he has said that hes already using gender as a way to run against her. Well, is he using gender or is she using gender . I think shes using gender as well. Im not going to adv
