Im in the middle of the water. Im like barely holding on right now. Calling for help on a stashed away cell phone. The dramatic rescue just in the nick of time. Do you believe in magic and harry potter returns. The boy wizard casting a new spell. His eighth story under tight wraps ready to be revealed just hours from now. Let the feast begin. The massive muggle mania taking the world by storm. Good morning, everyone. We want to say thank you for joining us. Great to have ryan smith with us, as well. We do want to start with breaking news. Were learning this morning about new terror arrests in belgium, a nation still reeling from the bombing of the Brussels Airport attack back in march for which isis claimed credit. Two brothers under arrest accused of planning new attacks in a country and continent on high alert. For the latest on what is a developing story this morning, lets go to abcs Jennifer Eccleston who is in our london bureau. Jennifer, good morning. Reporter dan, belgian prosecutors are confirming the arrest of two brothers. Suspected of planning a terrorist attack. They were named as 33yearold noureddnne h. And hamza h. After cities were raided in liege and mons. Now, month is significant because its home to a large nato up thatlation. Police say no weapons or explosives recovered but there were indications of plans to carry out attacks somewhere in belgium. The country is currently on the second highest security alert indicating a possible or probable threat. This comes after the march bombings at the Brussels Airport and metro station which killed 32 people merging 2 americans claimed by isis. As of now prosecutors say the two arrested are not linked to that attack and both will appear before a judge later today. Paula. Definitely a developing story. Jennifer, thank you. We want to move now to politics and more troubles for the democrats. There have been several high computer hacks in the past week and this morning concerns that Hillary Clintons campaign was targeted as well. What could have been revealed . The fbi is now involved and abcs mary bruce has more on this fastmoving investigation. Mary, good morning to you. Reporter good morning. Well, first the dnc was hacked then concerns about another Democratic Group and now Clinton Campaign data . But the clinton camp this morning is saying, not so fast. This morning, concerns about Russian Hackers meddling in the u. S. Election are growing. First the dnc was hacked, now it turns out Clinton Campaign data fell victim too. But the Campaign Says its own computers were not attacked saying they have found no evidence that our internal systems have been compromised. They do admit a dnc Computer Program which the campaign uses was accessed in the initial hack but say any information gained was publicly available. Nothing personal like supporters Social Security or credit card numbers. But the Trump Campaign doesnt seem to be buying it saying in a statement, this seems to be a problem wherever Hillary Clinton goes. Hopefully this time there wasnt classified or top secret information that puts american lives at risk. This after an embarrassing email hacking scandal at the dnc led to political mayhem forcing the party chair to resign at her own convention. All signs point to russia and now the fbi is broadening its investigation to include another Democratic Group, the House Democratic campaign committee. Russia in the past has tried to influence elections in europe and we take seriously their past record on this. Reporter Top RepublicanSecurity Experts are calling on congress to launch its own investigation saying the hack is an assault on the integrity of the entire american political process. Now, the cia director is vowing to find out who is behind all this saying overnight that interference in the u. S. Election process is a very, very serious matter. Dan. Serious, indeed, mary, thank you. And in the midst of this hacking story and hot on the heels of the Democratic National convention Hillary Clinton and her running mate tim kaine are on a bus tour through david wright is out on the campaign in pittsburgh. David, good morning to you. Reporter good morning, dan. 100 days, the home stretch begins for this Crazy Campaign here. The Clinton Campaign traveling today through pennsylvania here and ohio, battlegrounds both hoping to maximize that postconvention bounce. We have 100 days to make our case to america. Reporter Hillary Clinton joked that she and her husband needed their Morning Coffee through an i. V. Drip as they set off on their bus tour after a late night celebrating in philly. Joining them out on the trail her running mate tim kaine and his wife. Now, this is the part of the campaign i really like. Reporter worth noting, bill clinton was mostly a silent partner on this first day just like mrs. Tim kaine, auditioning for his role as first gentleman. It takes them through two key battlegrounds, pennsylvania, where the polls show her nine points ahead and ohio where the two are dead even. These are among the handful of socalled purple states, swing states that will likely end up deciding the general election. Were going to be visiting a few places where people are making things. I find it highly amusing that donald trump talks about make America Great again. He doesnt make a thing in america except bankruptcies. Reporter donald trump is in colorado, another big battleground. If i dont beat crooked Hillary Clinton, i will consider this a tremendous waste of time, energy and money. Believe me. And back now with david in pittsburgh. David, i want to play you part of an exclusive new interview that George Stephanopoulos did with donald trump. Trump is pushing back against Hillary Clintons assertion he doesnt have the temperament to be president. Take a listen. Polls do show concern about this, whether you can be trusted with the nuclear codes. Well, i think thats probably because hillary, thats all they talk about is temperament. I think i have a great temperament. I beat 16 very talented people in and ive never done this before. You dont do that with a bad temperament. Im leading her in the polls as you probably have noticed. And i think i have a great temperament. I have a temperament where i know how to win. She doesnt know how to win. Shes not a winner. This country, if they choose her, this country will not be in good shape. So, david, are we seeing here the preview of the lines of attack that are likely to dominate in the next 100 days of the general election . Reporter very much so. Dan, youve got Hillary Clinton attacking his temperament and using Donald Trumps words against him and donald trump attacking her character using her record against her and two thoughts occur, one of them is that both of these candidates have proven to be pretty resilient when it comes to character attacks. So its bound to get ugly. The other thing is that youre seeing both of them use humor, mockery to try to bait each other and try to get under each others skin so these attacks are likely to have sharper edges and a faster spin than what weve seen in the past. Dan. Sounds like it will be a pleasant 100 days. David, thank you for reporting this morning. And a reminder, everybody, you can watch georges full oneonone interview with donald trump tomorrow morning on this week right here on abc. We do have new concerns this morning about the zika virus here in the u. S. After Health Officials say mosquitoes in florida likely infected four people. Yeah, this is really a worrisome new development and abcs eva pilgrim is on the story in miami this morning. Eva, good morning to you. Reporter good morning, guys. We are standing in the area of concern. Its a onesquaremile radius and Health Officials say the zika virus is pretty contained right now to just this neighborhood but they are making sure people here know what to do to keep this from spreading. This morning for the first time confirmed cases of zika contracted right here in the u. S. Health officials investigating four cases in florida. One of these four cases involves a woman and the other three cases involve men. They are all active zika cases. Reporter workers now going door to door handing out flyers hanging these tags on front gates. Dr. Eileen marty, a disease specialist at fiu is also getting voluntary urine samples from residents to test for zika reminding them to take extra precautions even if they arent worried for themselves. Sometimes a disease can be very concerning, not because how it impacts you but how it can impact on your neighbors. This is one of those diseases. Reporter zika is especially dangerous for pregnant women. While the symptoms are often mild the disease can cause severe birth defects. These prevention kits being handed out to pregnant women by doctors and county Health Departments include insect repellent. If we can keep low the total number of people who are infected in our state, we decrease the chances of pregnant women becoming infected by mosquitoes within our state. Reporter so far there have been almost 1,700 people who have gotten the disease while traveling to a country infected by zika mosquitoes or by having sex with someone who has traveled and been infected. Health officials in miami confident they can contain the outbreak here locally. But thats not to say that if you contain this outbreak, there wont be another traveling person that infects another mosquito in another zone. Reporter the cdc is not recommending people limit their travel to miami at this time but Health Officials are telling people that live anywhere near mosquitoes to exercise caution and wear repellent, paula. Yeah, concerns about the domino effect too. Eva, thank you. Brazil is ground zero for the virus and earlier i spoke to abc news chief health and medical editor dr. Besser who is in rio in the leadup to the olympic games. Dr. Besser, thanks for joining us this morning. First and foremost, there are 1,600 cases of zika here in the u. S. But with these four in miami, they were likely transmitted through zika infected mosquitoes so how serious is this . Well, it is serious. You know, what it indicates is that people who come back from countries where zika is spreading do pose some risk. We have the mosquito in more than 30 states that can transmit zika if it gets infected and what were seeing in florida in a limited area there are some of those mosquitoes that are spreading zika. Is there a legitimate concern . We know pregnant women are disparately affected but lets say a man and his partner want to get pregnant down the road. Is there concern about that . What weve seen so far is that men can harbor the virus in their semen for at least 100 days. And thats only the little bit that we do know. We dont know how long that can be and so for some people theyve decided they dont want to take that risk. So what can we do to protect ourselves . First anyone who is traveling to an area where zika is transmitting, when you come home, use repellent for three weeks. That way you wont be that person who infects the local mosquito that then makes a pregnant woman sick with this. The key is keeping pregnant women safe, so use repellents in areas where mosquitoes are biting, make sure your screens are repaired and get rid of any freestanding water that could breed mosquitoes. These things will do a lot. Important advice. Thank you so much. One of dr. B. s other big concerns is Congress Left for seven weeks without approving the money that the Obama Administration had wanted to really combat this particular virus so thats a big concern for him. And as we all know, looming over the olympics and now looming over miami, as well. A lot of other news this morning including some breaking news out of washington state. Ryan smith is in for ron this morning. Great to have you, sir. Thank you so much. Good morning, guys, and we begin with that breaking news overnight in washington state.
