Trump campaign. Just a little earlier, Newt Gingrich was on the floor. We caught up, saw him doing his walk through. He has been somewhat critical of the bigname republicans who did not show up here. He called the bush family childish for not coming. He says he encouraged trump to pick mike pence as his running mate in order to unify the party. Earlier, we saw trumps son, eric, doing his walk through. He has a big speech planned for tonight. And out of the controversy with Melania Trump speech, eric said he use nod speech writers, that it will come from the heart and he wrote every word of it himself. Donald trump arrived here in cleveland a little while ago. He met up with governor mike pence. He told the crowd were going to win ohio. Karen, your whole family is an incredible family. We love having you with us in this endeavor. Hopefully, well do an amazing job and an amazing job for the country, most importantly. So, thank you very much. And congratulations. Fantastic job. Thank you, everybody. Were also getting some new insight into why donald trump picked governor pence as his running mate. Donald trump jr. Said hes sort of the yin to his fathers yang.

In about ten minutes from now well bring in nbc news political editor, mark murray, who will go over some of the final points for this pick and what tonight could mean for the well see you in a few. Chris lawrence. Chris, thank you. A staff writer for the Trump Organization is accepting blame today for the plagairism controversy surrounding Melania Trumps speech. She said she offered her resignation but the trump family rejected. She said she asked mrs. Trump to provide some messages she wanted to share with the american people. Over the phone, mrs. Trump read passages from mrs. Obamas Convention Speech as examples, and they ultimately ended up in the final draft. Ma krch mac gls guyver said i did not check mrs. Obamas speeches. This was my mistake and i feel terrible for the chaos i have caused melania and the trumps, as well as to mrs. Obama. No harm was meant. Right now at 4 00, some people are still cleaning up after last nights storms. One neighborhood along especially hit hard. A large tree demolished this porch after it came crashing down from the yard next door. And a large oak snapped like a pencil, landing on the rooftop of another house nearby, clearing the debris at this location is going to be a twoday affair. Its been heck all morning. This is a mess, back and forth. And getting trees off these houses, its not easy. Montgomery county fire says several homes in the four corners area were also damaged by lightning strikes. You know, the white house isnt immune to weather either. High winds snapped branches, leaving a lot of debris on the front lawn of the white house. Crews also cleaned up the mess across the street in lafayette park. Chris gordon is live in bethesda where a tree nearly hit a couples home there. Chris . Reporter yes. Well, here, the 5900 block of cleanup. Take a look over here. Power lines are down because of this big branch that fell down overnight, tearing them down. People in this neighborhood have been fearful of this what they call the dominant tree. Its big and its old. They were afraid the next severe storm would tear it down and create serious damage. And thats what apparently happened here. Tree crews cut and cleared parts of this branch, bigger than many trees in the neighborhood. It was torn down when the storm hit bethesda last night. Power and phone lines are strewn across the drive. Intense rain. Lots of thunder. Saw lots of lightning. At some point we heard a big crack. My wife said oh, that sounds like a tree. Reporter peter dolan and his wife were in the upstairs bedroom of their home when the branch hit the gutter on the corner of his fortunate i feel. Had the tree been ten feet farther to the left in our ho e house, it would have seriously damaged not just the roof but the structure as well. Reporter now lightning hit a ho home.

First at 4 00, new lawsuit says drivers are being tolled illegally along the dulles toll road to adam tuss has been reading through this new lawsuit and has details. Reporter this lawsuit claims a couple of things. First, it says drivers here along the dulles toll road are being charged illegally to help finance the silver line. Certainly, there are plenty of drivers coming through here. But the other charge in this case is against the airport authority, which now operates the toll road. This lawsuit says that the Airports Authority basically has Unlimited Power to do what it wants to do. We talked to the lawyer in charge of this lawsuit today. If theyre going to take money from you, you get to vote the bums out if you dont like what theyre doing. And this authority is structured to be independent from all over forms of government.

Get ready, folks. Some serious heat headed our way. Wait till you see how hot it will t for the wgeee im Chris Lawrence. Back here live at quicken loans arena with the Republican National convention. A lot of people find this point in the Convention Rather boring. Its the walk throughs, the preproduction leading up to tonight. I find it one of the most interesting times, because its one of the most unscripted times that you will find here, as people try to fine tune where theyre walking, what theyre going to say, who is going to go where. You see all the people preparing for what is sure to be a big we are also joined right now by nbc news senior political director mark murray. I had a chance to talk to mark a couple of hours ago. We talked a little bit about the messaging coming out of this convention. Mark, i want to ask you, what do you see when you see the trump family giving one image of him but yet some of the politicians seeming to give off a completely different message . Youre right there have been two messages going on here in cleveland. From one hand we saw it from the trump family, friends, business associates, giving testimonials to donald trump, speaking about him as a man to make him look like a three dimensional president ial candidate. On the other hand, weve also seen some very tough speeches directed at Hillary Clinton. In fact, i would count by my count there were twice as many anticlinton speeches as there were pro trump speeches last Republican Convention and one trend has emerged where most of the anticlinton speeches have been coming from republicanelected officials, party operatives, people who are a lot more comfortable going after clinton than they necessarily are giving fullthroated endorsements of donald trump. Those have been the two messages going forward. I wouldnt be surprised if i end up seeing more anticlinton speeches tonight. Yes. Its interesting, mark. At one point last night, i was hearing the name Hillary Clinton more than i was hearing the name donald trump. Its just an interesting point. When you look in terms of attracting voters, which is where this all has to lead to some time over the next hundred days or so, what does it tell you in terms of who has been brought to the stage and who is being highlighted during these prime time hours . Well, you know, obviously the republicans have wanted to make a message on the people theyve particularly in the prime time hours between 10 00 and 11 00 have been attacks on Hillary Clinton. I was struck last night where you ended up having the senator from West Virginia who ended up giving a really big attack on president obama and Hillary Clinton and talking about the importance of West Virginias coal industry. That is a play that donald trump has been making in coal country. Coal country has a big role in pennsylvania and ohio. One of his big messages has been going after a lot of these disaffected workers, people who live in appalachia. Not focusing on the diverse states like colorado and, of course, virginia. Reporter thank you very much. Diversity within the party, thats something were going to be diving into throughout the night here. I encourage you to follow mark on facebook. Stay with us. The bottom of the hour. Ill send it back to you guys in the studio. Thank you, chris. Turn to that weather. What a scorcher again. Getting a little bit of a break today.

Green is good. Yellow, orange, be careful. Red. Then theres purple. Not a human should be outside. What is in the air . What that what you need to worry about is this Chemical Reaction between oxygen and pollution. Heat puts it all together and you get this thing called ozone, a caustic chemical. I see people jogging on the Memorial Bridge at noon on these nasty days. Whats it doing to your lungs . It literally burns. Really . People will have worse reactions to that burning. Anybody who breathes needs to worry but certainlyasthmatics, young, old. Hot and nasty one day and we have this rain and its good the next day and then the heat returning, is it actually clearing out the atmosphere . No. Remember, were talking about a Chemical Reaction. That Chemical Reaction is burning. Where you really see the results of that inflammation is usually prolonged exposure will give you prolonged inflammation. It doesnt get better the next day. In fact, youre not going to see it for two days. Will you feel it . If youre healthy, will you feel it . You can. It can zap your energy. You can be exhausted. Thats why . Yes. Interesting. You always think its just the heat. It affects other parts of your body as well. Some interesting studies have been done where it affects your heart. You can see an increased risk of heart attack and stroke. It also affects your brain. In the elderly, they see a decreased cognitive effect. You get more forgetful the older you get. Interesting. Do we just stay indoors . Is it just that easy . In some ways, yes. When its really that hot, you should really just stay indoors. I would like people to change their routine. If you normally were mowing the lawn in that hot and breathing in the fumes in the pollution, do that when its not so hot. Do not exercise outside in the heat. Do youre going to breathe more of that burning ozone into your lungs. Be careful about that. Some people are more susceptible than others to having this happen. There is a gene that protects some people. Unfortunately 40 of people dont have that gene at all. And some people are living in the wrong place. Especially young children. If youre living next to a lot of pollution and a busy roadway, youre more likely to have asthma. What do people down in arizona and palm springs do in the summer when its 115 degrees . They literally stay inside and with their air conditioning. But that can cause a problem, too. So theres no damned if you do and damned if you dont. No easy way out on this one with the air conditioning. Whats it doing . I see an awful lot of people who will say i think im allergic to air conditioning. They will get a stuffy nose, runny nose, bronchospasm. Theyll start to cough. Air conditioning itself can pass around lots of germs legionaires disease. It was very good at making that bacteria go around or the mold and fungus that can grow in that system. So air conditioning is not a free lunch, so to say. You can have your own Health Problems for that. Bronchospasm that people get to the air conditioning, there are sprays we can give you for thos those. Delightful. Dr. Jackie, thank you so much. By the way, we just posted six ways to keep you cool on our nbc washington facebook page. Take a look at it and share it with your friends. Jim . Come into our studio. Its a meat locker. Yes, it is.

While uncommon, meningitis b can. Lead to death within 24 hours. Trumenba is a vaccine for 10 through 25 year olds to help prevent group b meningococcal disease.
