Will there be an intervention . Our decision 2016 team has had jackson. Hallie, good morning. Reporter good morning. This morning were at the start of a critical window for donald trump to show he can make a comeback after a couple of the worst days of his campaign yet. You can call it a tale of two campaigns. Publicly advisers insisting theres no intervention, no drama, no panic. Privately Top Republicans telling nbc of a deep and growing frustration as trump fends off contr backstage. Just a little while ago i met with the gold star families. The love in that room was so incredible. Reporter Donald Trumps meeting coming as he faces fallout from his criticism of two other gold star parents. You have sacrificed nothing. And no one. Reporter just one in the long list of controversies trump is trying to get past as a new nationally and now upping the attacks on her after a reported 400 million secret shipment to iran returning iranian cash part of a settlement over a failed arms deal at the same time as release of american detainees. Can you say i wonder what happens with that 400 million . I wonder who ends up getting it, right . Reporter clinton forced to defend the controversy. As far as i know it had nothing to do with anyin hostage swap. Reporter trump staying on script. What his campaign wants to see. This was all started by Hillary Clinton. Reporter its republicans trying to hit reset. Trump supporters like Rudy Giuliani are hoping for a possible intervention in an effort to get the trump train back on track. Newt gingrich telling the washington post, trump is more now. Frustrated republicans calling trumps refusal to endorse paul ryan a major misstep. His own running mate, splitting off to back ryan himself with trumps blessing, he says. He strongly encouraged me to endorse paul ryan in next tuesdays primary, and im pleased to do it. Reporter trump advisers pushing back on reports of a campaign in crisis. The candidate is in control of his campaign. The campaign is in very good shape. We are organized. We are moving forward. Reporter trumps children. Some of the few people with sway over their new notoriously unpredictable father as trump gets good news on the money front raising about 80 million in july with the party, his campaign says. The most of any month yet. Through all of this, the Clinton Campaign is actively courting republicans and independents with a new big name gop defector, meg whitman, a top businesswoman and donor. Leading trump including in New Hampshire as trump heads to new england today with a town hall set for maine. Savannah . Hallie jackson, thank you. Chuck todd is in washington for us this morning. Chuck, good morning to you. I know youve been reporting about the feeling among some republican officials that maybe there would be a way that trump would actually withdraw from the race or be persuaded to do so. Is that real or is that establishment fantasy at this point . I think its a fantasy. I cant believe yesterday where that issue was there. That somehow in a meeting with him they could convince him to do this. I think thats definitely fantasy. What really theyre hoping to do is in the same way that you had Republican Leaders who were unhappy with trump, they went to his children, they convinced him to change Campaign Managers and it was the children that finally made that happen. They convinced him to pick mike pence over his own gut which was that. Again, the children were involved. I think realistically what they hope to do is say good grief, can you at least put some structure in place. Can you not do 17 interviews in between rallies and get yourself off message and stop attacking this person and stop attacking republicans. I thinker who hoping realistically with the help of the kids provide structure and tone it down. What republicans, if it was any other candidate running against Hillary Clinton, this would be a rough patch for Hillary Clinton given some of the items in the news. Incredibly rough patch whether its the current state of the economy, anemic growth, whether it is her insistence that somehow director comey let her off the hook on emails and she sort of reinterpreted what comey said in a way that was misleading. Throw in the discomfort from never mind we just started air strikes in libya because isis is there. Libya was a high profile intervention and Hillary Clinton push. The point is in the last five days this could easily have been Hillary Clintons worst five days postconvention and instead the exact opposite and its all due to Donald Trumps lack of selfdiscipline. I have 30 seconds and two raw politics things. Talk to me about polls and the fundraising game. I can tell you the polls look like it could be next week by donald trump. All hints are this bounce is real and you see it trickle into the states. We could see double digit leads for clinton in swing states. The money, you have to say that donald trump looked like a National Candidate that you would expect a mitt romney to have looked like four years ago with the amount of money he raised in july. July was a great month. July was the most unified the Republican Party had been in seven months. From small donors. Small donors. Though after six incredibly bad days for him. Chuck todd in washington, thank you so much. Chuck mentioned the Obama Administration is once again raising concerns about funding the fight against zika as officials deal with the outbreak of that virus in miami and this morning were learning about new cases in u. S. Military. Nbcs Kerry Sanders has the latest on this. Kerry, good morning. Reporter good morning, savannah.

All of the cases outside the United States. Six family members of Service Personnel have also contracted the virus. The news comes as Health Officials in the United States are now cautiously optimistic they can get the homegrown virus now in one area of miami under control. I dont think it will be easy. I think it will be difficult. I do believe we can contain from the air spread a tenmile zone. Is it safe . You can never Say Something like that is 100 safe. You should tell people if they see the plane coming over, to go inside. Its just the prudent thing to do. Reporter the mayor of miami thinks the city is being prudent when it comes to the wynwood neighborhood, center of the outbreak, but hes concerned that fear is hurting the local economy. Its impacting the image of thats been misinterpreted. Dont travel to miami. Reporter at the body belly baby class which isnt near wynwood, pregnant women like amanda are scared.
