An alarming rise in one of the most aggressive and deadliest kinds of cancer, doctors calling it a wakeup call for men to be screened. Nightly news begins right now. Announcer the Republican National convention, this is nbc nightly news with lester holt reporting tonight from cleveland. Good evening. With the Melania Trump plagiarism controversy buzzing around this convention hall, including some late new developments, a traditional rite in american political conventions is under way, behind us the roll call of the states is being taken right now. Delegates of the Republican National convention are formally voting on the nomination of donald trump as their partys president ial candidate. We can listen in a little bit. I think this is hawaii. The great state of hawaii, donald trump, 11 delegates. Cruz, 7. And marco rubio 1. The state of new york is hoping to be native son over the top here shortly. But trouble has been brewing on the floor tonight. Some donald trump resisters are making their feelings known. Peter alexander, whats happening there . Reporter this is always a pageant of party, fervor and state pride, colorado one of those states that may have tried to cause a raucous tonight, potentially trying to embarrass the trump cam pain. But the majority of these delegates into to donald trump but not making a fuzz, means the antitrump movement has fizzled. This is the moment when the Republican Party tries to present themselves as united. Working their way through the room, alphabetically, as they get close to that 1237 magic number, they will skip ahead to the state of new york, where Donald Trumps son, donald jr. Will put donald trump over the top. The unexpected controversy that erupted l melania spoke at the convention, her words to the crowd were largely well received until it became apparent not all of them may have been her words, but rather those spoken by Michelle Obama eight years ago. There is important late new information breaking in the story. Lets get more from nbcs hallie jackson. Reporter the candidate to rarely minces words, now under fire for his wife. Donald trump needs to use the line, youre fire. Reporter Donald Trumps campaign pushing back on plagiarism charges. There was nothing that she did in that speech that she felt was anybodys words but herself. 90 of the speech was different than Michelle Obamas speech. That was Michelle Obamas 2008 speech, strikingly similar when you listen to it side by side. You work hard for what you want in life, that your word is your bond that you do what reporter donald trump told matt lauer i wrote it with as little help as possible. Reporter Campaign Sources tell nbc news a staff member was assigned to oversee each family members speech, melanias the most important. But jared hill thought it sounded familiar. I had a double take, of that sounded really weird. Why do i know those words from Michelle Obama and that kind of set it on a track to figure out what it is. Reporter his tweets about the speeches spreading fast on social media. Trump supporters say it wasnt plagiarism, just common klee slays. John legend said work hard, twilight sparkle from my little pony said this is your deem. Reporter the campaign trying to stay on message. The speech itself was graceful. But now were not talking about the speech. Were talking about the process by which the sp w that indicates the campaign is not ready for prime time. Reporter after night ones grand entrance, the grand slam was supposed to be to show trumps softer side and to try to show women hes a better advocate for them than hillary cli clinton, highlighting the mother of a victim of the benghazi attack. How could she do this to me . How could she do this to any American Family . We need to get our country back. Were headed in the wrong direction and he is the man to bring our country back. Reporter for trump, racing to lock up conservative support, those are the words he would rather be talking about. Sources close to the campaign tell nbc news the trump team fired matthew sully, a professional speechwriter to write Melania Trumps speech. None of the portions in question, the changes occurring after the speech was delivered to the campaign. Two more family members are set to take this stage tonight, all of it, lester, occurring against the backdrop of all of this, donald trump now being delegates as the republican nominee. Lets bring in chuck todd and savannah guthrie. Savannah, this campaign has breezed past a lot of controversies, why is this one so difficult to get past . I think they are making it more difficult for themselves. In the bestcase scenario, you have somebody who made a very sloppy mistake, maybe it raises questions about the competence of the campaign that nobody caught it. But today, to have an array of different republican surrogates come out and tell people with a straight face they didnt care what they clearly can hear, when you have portions of a speech that are almost identical word for word, now you add a question of the credibility of the campaign, on top of the confidence. People know what they heard, and i think they would be willing to forgive it. But for the Campaign Surrogates who say, this wasnt listed, this wasnt a mistake, your ears are deceiving you, i think they compounded their problem that a story that could have been over by breakfast time compounded tonight. This process, the actual nominating process takes place, even this hasnt gone without controversy. Its actually been smoother today than yesterday. But the other issue here, this could have been a speed bump, a little hiccup and they move on, but its been emblematic of this entire convention. And the vp rollout. That said, a little preview of tonight. I call it establishment tonight. Youre going do see actual elected republicans quietly make their case for trump. Are they making the case for trump or just against Hillary Clinton . We did not hear a lot of pro trump speeches last night. We heard anticlinton speeches, he needs some trump system tonight. Tonight were learning new details about a terrifying attack on a train, an afghan teenager pledging allegiance to isis, attacking passengers with a knife and an ax, nbcs bill neely on the reporter holding a knife and calling himself an isis soldier, this 17yearold promised a suicide mission.

A new report shows a dramatic increase in new cases of the deadliest most aggressive form of Prostate Cancer. And as nbcs ron mott explains, crazy new questions about the guidelines for screening men. Reporter theres alarming news about the deadliest kind of Prostate Cancer, it is on the move. A study of over 8,000 men showed a dramatic increase in advanced ca c surge, men 55 to 69 almost doubled in number. The goal is to look at the numbers. Reporter study author dr. Edward shaffer says the possible reason is the disease may be turning more aggressive and fewer men are getting screened. I think the take home message for the study really is that we need to be certain that were on the right track and really maybe rethink how were crafting our guidelines to screen men with Prostate Cancer. Reporter when caught early, Prostate Cancer is virtually curable, with survival rates nearly 100 , but when its caught after its spread, about 3 4 of patients die within one year. Psa screenings have dropped. In my mind, the data is very clear that screening for Prostate Cancer saves lives.
