Donald trump claims party unity. What . What is he doing . Donald trumps worst enemy is donald trump. He is just a terrible candidate. No more talking about paul ryan or lindy graham or ted cruz or john mccain. Donald trump should focus on the democratic nominee. Hillary clinton, she should get an award from them as the founder of isis. Its what it was. I frankly thinks its br you hear youre hired, instead of youre fired zika continuing to spread and 33 military members including one pregnant woman infected while serving overseas. The chaos inside a passenger jet crash landed in dubai. Jump a woman killed and five people injured in a knife attack in central london. I can say that the woman who was murdered was an american national. Central america. It made landfall in belize after hitting honduras with heavy rain and high wind.

Im disappointed in the lack of enthusiasm here. Im a good or not. People are shocked. People are shocked. But let me sorry. I should play obama for the presidency. On cbs this morning. Ill do it. Im guessing, really, that this is just wishful thinking, but senior gop officials are exploring options if trump drops out. In fact, Top Republicans have been seen standing outside mitt boxes announcer this portion of cbs this morning sponsored by toyota. Lets go places. . Welcome to cbs this morning. Donald trump is falling further behind Hillary Clinton in the president ial race. The latest National Poll shows clinton has opened up a tenpoint lead during a rough week for trump. Clinton has 49 , trump, 39 . The republican standard verifies himself facing more criticism within his own party. Members of the party and controversial comments could cause lasting damage to his campaign and the party. Major garrett is in jacksonville, florida, where trump dismissed signs of problems. Reporter good morning. Trumps Campaign Woes have been well chronicled all week and those close to donald trump admit his lack of discipline is quick temper but the prospects of victory against Hillary Clinton in real jeopardy. Even here in florida where zika is understandably a big topic, trump has no plans to battle the even so, trump insists, and he means everything, is just fine. I have to say, our campaign is doing so nicely. Reporter during a swing through florida, donald trump insisted all is well, even though his most ardent supporters fear trumps fall in the polls could be irreversible. I think some of what trump has done is very selfdestructive. Reporter in daytona beach, trump Hillary Clinton ads. You got to see this guy. I dont remember. Blood coming out of her whatever. I meant her nose or on her ears or her mouth but these people are perverted. Megyn kelly and a disabled reporter, trump drew to clinton talking point. It was graveling. I wont make the motions because if i do, they will say something, you know . Trump admitted his critics have a point in picking unnecessary fights. I think they are right. More focus on Hillary Clinton. She is a disaster. Reporter by a wide margin, voters feel clinton is more qualified to be president. Trump is the most competitive with clinton on the handling of terrorism and national security. Where the two candidates are tied. It was Hillary Clinton that she should get an award from them as the founder of isis. Reporter trump tried to a lengthy criticism of the Obama Administrations Cash Transfer to iran at the time. Four u. S. Hostages were released. Its being shipped overnight to iran. 400 million. Reporter but then veered way off track, describing a socalled secret videotape. And the tape is of the people taking the money off the plane. Right . Us the tapes. Reporter trump mentioned what he called a socalled secret videotape twice yesterday, but his facts simply do not line up. According to the Trump Campaign, this is the video the candidate was referencing. It is footage of u. S. Hostages landing geneva and not footage of cash to officials in iran. No videotape of a cash to it. Dan senor, welcome. Good to be with you. Tell me what series of events could put donald trump in a point of no return . Are we headed for that moment . Well, look. If he continues week after week attacking people who are not conventional political adversaries. Trump punches back at him and calls him little mike. Like judge curiel i think youll see that week after week where the Clinton Campaign bastes him with figures and it looks like he is punching down and that is a deflection point. I think we will see trumps polling come down which we are already starting to see and he had a good fundraising month but i dont think its sustainable if he continues to behave and perform like he is and fundraising will take a campaign and rnc are drying up i think you could see real panic setting in. Yesterday, he said our campaign is more united than ever before. There are reports that people want to have an intervention for him. Prominent gop leaders are defecting from his campaign. How do you describe this . How do you describe it . They can sit there and say everything is just fine . They have also said the nfl sent them a letter about the debates which wasnt true and true. No request was made. I think he has a tendency to assert things that are not true and he hopes there is a fl flur that the media cant keep up with all of them. Anyone who argues this is a functional campaign and wellorganized by any metric, Republican Campaign and democratic campaigns, nobody has ever seen anything like this. It is a oneman band and not a real campaign. We know the Hillary Clinton campaign is courting gop defections. What are you hearing in terms of republicans jumping ship sf . . There is more of them. Meg whitman a couple of days ago which is big and seth clarmon what raised a lot of money in the northeast for republicans came out and one thing never to be for trump but he is going to help Hillary Clinton assertively. Im hearing of others who are contemplating it and i think they will be coming out over the next few weeks. What is amazing to me is their most powerful republican in the country, the speaker of him. Yeah. No, by the way, paul ryan said two things to donald trump. One, i will endorse you but i will speak out when you say things that are offensive. But i will try to unite the party. If you look at the speech that paul ryan gave at the Republican Convention he named trumps name more than one and the unity of the republican party. In return, trump basically punches him which this is the opposite of party unity and isnt march or april. This is august and we are less than a hundred days. That is on major newspapers front page this morning. Ahead, Donald TrumpsCampaign ManagerPaul Manafort will be here in studio 57 and we will get his take on the rift between trump and Top Republicans and whether the campaign can get back on track. Hillary Clintons Campaign is playing offense on the economy today. The democratic nominee attacked donald trump yesterday for using overseas manufacturers in his would hurt the economy. Clinton campaigned yesterday at the maker at a tie denver. She will be in nevada today to an electric company. Nancy cordes is in las vegas with more. Reporter good morning. Clinton is going to make the case today here for a apprenticeship as an alternative to fouryear college. She wants to give businesses that hire apprentices a tax credit. The Clinton Campaign says plans like this or the fact that she has plans at all separhe this is it over here. Reporter in denver, clinton visited a Company Called naughty tie. She wasnt shopping. She was there to make a point about trump and outsourcing. He paid Chinese Workers to make trump ties. This is one of them. Its got his name on it, of course. And instead of deciding to make colorado with a company like naty. Reporter its part of trumps Business Practices that include this new ad. How is the trade to china . Reporter made in colorado, not china reporter clinton argued she, unlike trump, would launch a jobs plan as president. We are not going to let him do to america what he has done to so many other people reporter she got some backup hewlettpackard Ceo Meg Whitman who asked fellow rops to rejected donald trump this november. She joins high profile republicans not backing away from trump but embracing his opponent. The Clinton Campaign almost certainly has quite a number of others in their pocket. Reporter political analyst elaborate sabado says the gop donors and saying its okay to switch sides. Turn around and ask yuoursel a basic question. How many prominent democrats have endorsed donald trump . Reporter a new poll out this morning in New Hampshire has clinton leading by 15 points. This is a huge switch from may, norah, when trump was leading in a similar pole by two points. Nancy cordes, thank you so much. Ill be meeting up nominee tim kaine. Youll get a first look at the interview tonight on the cbs evening news and much more tomorrow on our show, cbs this morning. London police said minutes ago, that the woman killed in an overnight knife attack was an american. Five other people were hurt in the rampage in an area popular with tourists. The 19yearold suspect is in custody. Police, this morning, stepped up security. Elizabeth palmer is at the scene of the attack in loppeds Russell Square with the latest reporter good morning. Witnesses have told us that a man started stabbing people, apparently at random, just after 10 30 last night. Now, police came in minutes and tasered him but, by then, that on the sidewalk and five other people had been injured, one of them also a u. S. Citizen. We dont know the attackers ame yet, but we do know he was a norwegian citizen of somali ancestry. Moment he was not a terrorist and mentally ill but not rule out any extremist links until they have a chance to comb through his cell phone and his computer.

The arrest of Nicholas Young marks the very first time a Law Enforcement officer has been charged in connection with a terror case here in the United States. Jeff pegues is in watching him. Reporter good morning. Nicholas young was an armed cop who according to court papers, seemed paranoid being watched by federal agents. His suspicions turned out to be right. He had actually been on the fbis radar for the last six years. And investigators were monitoring what he was saying and doing. When he appeared in a virginia courtroom, Nicholas Young was shackled, wearing a tshirt and his uniformed trousers. The transit officer is facing a provide Material Support to isis. A Fairfax County native, young came to the attention of Law Enforcement as early as 2010 because of his association with known terrorism suspects, including amin. According to Court Documents in 2011 the two met in a restaurant. Less than a year later, khalifi was arrested for attempting a sued bombing in the u. S. Capitol building. The biggest reason this arrest is a concern because it was a a position of trust. Reporter Fran Townsend is the Senior National security analyst for cbs news. If he had used his access to Transit System to help them plan an attack in the United States, all of those things were certainly possibilities for someone in his position who wanted to actively support isis. Reporter investigators say they do not believe that young, who had been a transit officer for about 13 years was planning an attack on washingtons Public Transportation system. But they allege that over the expressed support for terrorist organizations. Court documents state that young admitted he traveled to libya twice in 2011 to join rebels attempting to overthrow the gadhafi regime and he knew how to avoid detection by u. S. Authorities. Court papers say young had a burner phone. He didnt know it but the person he told was an fbi source. It wasnt word, but actions that led to his arrest. Investigators say that he ultimately purchased gift card to give to isis operatives who he thought would use them for untraceable mobile messaging accounts but he was actually giving them to the fbi. Good work by the fbi. Jeff, thank you.
