myself, on the campaign trail, in the white house. >> she pointed to his years as richmond mayor, his time as virginia governor. is it enough? >> when i say he's a progressive that like to get things done, i mean it. >> the crowd got to hear from him knowing well the south florida audience he spoke at first in spanish. then addressed the obvious. >> for many of you this is the first time you've heard my name. >> for 35 minutes, he went on to detail his personal life and career, making several references to his catholic faith and virginia ties. and choking up virginia tech shooting. >> the worst day of my life. >> i asked those gathered what they thought. >> he seemed like a stable, ready-to-do the job kind of guy. >> before last night, you had no idea who tim kaine was. >> no, no idea. i'm so happy he will be our vice president. >> were you hoping for a riskier choice. >> yeah, i'm a bit of a gambler. >> who were you thinking? >> probably elizabeth warren, someone with a diverse background, african-american or latino. >> donald trump wasted no time reacting to the choice of tim kaine as clinton's running mate. here's what he said on twitter. the bernie sanders supporters are furious with the choice of tim kaine who represents the opposite of what bernie stands for and you can hear more about what trump has to say about his general election opponents when he joins chuck todd on meet the press thi senator bernie sanders will also be a guest on the show to talk about his role in the democratic national convention. meet the press starts after news 4 today at 10:30. well the democratic national convention kicks off tomorrow in philadelphia and like the republican convention in cleveland, security will be tight. nbc's gabe gutierrez has a look at the measures being put into place. >> in the city of brotherly love, the stakes are high. >> the declaration of independence was signed, a lot of history in this town, we want to make sure we maintain that history and keep it safe. >> with 400 miles of coastline to patrol, including one of the nations busiest ports, the coast guard in philadelphia is bracing for the democratic national convention, bringing in reenforcement, 21 vessels will morning secure areas near the wells fargo arena. >> we got to prepare any type scenario that might affect an event such as this. >> recent terror attacks around the world and police shootings in the u.s. have authorities here on high alert. today, barricades went up around the arena and there's already a heavy police presence downtown near the convention center. more than 10,000 demonstrators are expected in a city trying to avoid a repeat of the republican national convention 16 years ago when hundreds of protesters were arrested through thrashes with police. >> i think there are a lot of people upset with bernie sanders for endorsing hillary. among those is drew who is a former bernie sanders campaign volunteer. >> i think it's different because we're at a unique political moment. >> a moment he and the city hope will be peaceleful. some differences between this past week's convention and democratic one, philadelphia's police force is four times larger than cleveland and it already has last year's papal visit for a start. and we'll have lives reports from the democratic national convention in philadelphia starting tonight. it's a storm team 4 weather alert day, timing everything if you want to get outside. tom is updating his forecast of when we can expect to break this heat wave. and thousands of homes are in danger the new concerns in california squuuuack, let's feed him let's feto the sharks!sharks! yay! and take all of his gold! and take all of his gold! ya! and hide it from the crew! ya...? squuuuack, they're all morons anyway! i never said that. they all smell bad too. no! you all smell wonderful! i smell bad! if you're a parrot, you repeat things. it's what you do. if you want to save fifteen percent or more on car insurance, you switch to geico. it's what you do. squuuuack, it's what you do. someone may have been killed by the raging wild fires in california. a burned body was found outside a home near los angeles where a fire doubled in size yesterday. investigators right now trying to figure out if the person died from the fire or somet coming up on 6:12 on a sunday morning, let's go to tom kierein. yesterday, the pool was the place to be and not the golf course or yard work. >> yeah. it was a challenge too. at the nats game, even though it was an evening game, it was pretty warm and muggy last night. now today is going to be a day game and first pitch at 1:35, it will be in the mid 90s by then. dangerous heat during the afternoon. you have to get some yard work done or maybe you want to get in some exercise this morning, now is the time to do it. as we take a look outside, we've got a fried egg sun rise under way. live view from the storm team 4 tower camera and we'll be frying certainly by later this morning and into the afternoon hours. right now, though, it's pleasant. we're down in the 70s from the shenandoah valley to the chesapeake bay. but right on the upper 80s on the waters. as we look at nats park here for the game for the afternoon, they take on 1:35. it will be in the mid 90s as you are getting there, arriving to the game, then it will be in the upper 90s by the 7th inning stretch with hazy sunshine, very hot. all the way to the end of game. they will be up to 98 degrees by 5:00 p.m. by the end of the game. it's going to be quite a challenge to deal with that kind of heat during the afternoon. right now, don't have any showers or storms on storm team 4 radar. we could get showers and thundershowers popping up. these areas here, around the blue ridge and panhandle of west virginia. after that, they will be dissipating. evening hours, it gets more humid again. you may see the humidity drop a bit during the afternoon but it turns more humid as we get into the day on monday. and a greater chance of afternoon storms tomorrow, afternoon highs, upper 90s to 100 degrees. the heat index as we t into tuesday, still very hot in the upper 90s. if you've got weather alert days, today, monday, and tuesday, after that, we stay hot into wednesday and thursday with highs 90s, look at that, cooling down by friday and weekend, into the 80s. it will be in the yaths the first part of next week as well. before we knew who the vice-presidential pick of the democratic party would be, earlier this week, news 4 jewelry carrey moderated a round table discussion with jim warner and tim kaine. >> she started out asking about metro. >> if wouldn't be a conversation if we didn't talk about transportation. everybody in this room very aware of metro's efforts with the safe track. many of you rely on metro to g looking ahead, what's the best approach from both a state and federal level to ensure that metro is safe, reliable, and financially sound for decades to come and where do you see some of the challenges lie? >> i think the metro board made the right choice and i think he's brought a new found sense of confidence and i think it was absolutely appropriate for him to rip off the bandage and expose the challenges and i think he's got generally speaking the support of the public. as part of the congressional delegation, there was enormous frustration with some of the previous management's kick the can approach. number one. number two, we've got particularly some of our friends in the house who want to bash metro and then cut the federal contribution. i mean, this is system as wl as our region's transportation system. it is the obligation of the largest user to help be one of the funders. the challenge with that is if you've got a system that has some financial issues as well as safety issues, you cut the funding that reinforces the inability to get things done and it creates that vicious downward cycle. we have to maintain, i think, the $150 million plus on the federal level and we need to see a turn around both in terms of safety and in terms of culture and optics. i'm glad that they have gotten rid of some of the employees that have not performed. you need to send that message across the workforce and then from the region, we need to make sure that the three-state compact is actually put in place and that oversight is done on a more regular basis. >> this region doesn't work without metro and agree with mark. we spend a holmes norton, the virginia and maryland congressional delegation. a couple of times we were sitting down with the leadership and i was extremely disappointed with the leadership and the vacancy of that critical gm system. you cannot have a board to run this. you got to have a gm. when paul was hired and we felt a good sense of things and -- >> even he was from maryland. >> right. and he made an unpopular decision really early when he said we're shutting the system down today because of these arcing problems. people were so mad. i want a gm that will make that decision if he thinks safety is compromised, you got to do that. and then this significant year long ten major projects that they are going to do, that will inconvenience people, but i live in richmond. you guys are the savviest commuters anywhere on this planet. the most popular column in the "washington post" is dr. gridlock, what i notice is something like this fast track program, you are really savvy. you get advance notice, here's a section where there's going to be work these days, everybody knows the hacks and work arns if you know about it. paul did this to send a message to congress because the notion of metro coming up and say hey i know we're not running well, give us more money. forget it. that ain't happening with this congress. to lead with, we're giving people advanced notice. we're not afraid to make a hard decision. then you build the foundation to come and ask the financial support you need. he's putting the steps in the right order. i'll tell you one thing that we're going to have to grapple with. i agree with what mark said. the fun thing about doing this job is to be doing it with a job of 37 years, and, you know, to -- i know what he thinks when i'm looking at his face, he doesn't have to say anything and vice versa. we've really had an ally with barbara miculsky has been rock solid on. here retirement we're going to have to pedal the bike a lot harder. we in virginia out to remember to thank her for all the virginia priorities. >> we talked about -- when i was governor, the smartest thing about it we changed it to mid atlantic space port and put her picture on the wall. fios is not cable. we're wired differently. so we wired the wagner's house with 100 meg internet. which means that in the time it takes mr. wagner to pour a 20 oz. cup of coffee, tommy can download 30 songs, and jan can upload 120 photos. 12 seconds. that's the power of fiber optics. and right now you can get 100 meg internet with equal upload and dowloads speeds, tv and phone for just $69.99 per month online. cable can't offer internet speeds this fast at a price this good. only fios can. how do you think virginia is positioned right now for the next round of base and closures that we're set to hear about could happen the next few years? and in this post sequestration world, how can virginia protect its assets? >> i'm on the armed services committee and i spend the most of my time. start with the statement, you don't want excess infrastructure sucking up costs that you could be putting on more focused efforts to defend against tomorrow's threats than yesterday's. the question you have to gaple with in armed services what's the right level? i have been a brak target and i've been on the armed services committee. i was a mayor. i was the governor. i don't like the way braq is done and i'll tell you when it gets announced, every community has to hire lobbyists and lawyers to make their case, even in communities where their military facilities have no danger to get shut down. everybody hires lobbyists and lawyers and they waste tons of monies and the braq process, there were some quirks, i don't think it's a great process because it makes everybody frightened and everybody spend a lot of money when usually the right way to deal with infrastructure issues are very targeted. i've asked this question. the pentagon makes recommendations to congress every year. buy this weapons system, don't buy that one. change military benefits this way. not that way. and they make recommendations to us on really controversial things, you know what we do in them and we change about 20% of them and say hell no to 15% of them. we're perfectly capable of taking professional recommendations and out of their own perspective some of them and not yet. i think the dod should do the these things. whether it's bases at home or bases overseas. these are tough things. i get the politics hard and it's going to go through a meat grinder when it gets submitted to congress but i think the dod should just treat infrastructure like they treat everything else that's controversial. just make a recommendation. virginia has not only more assets than just about anybody, but the good news is a lot of our assets are incredibly strategic. speci of all marine officer training in the united states and so there are real particular equities about a lot of our installations, but i think one of things about being a senator is -- in the senate, you are supposed to be country first and state second, and then partisan 99th or distant third, you got to put country first and we shouldn't be trying to just embrace excess and unnecessary infrastructure that's going to cost us in terms of the effective ofness of our defense. i would just have the dod make tough recommendations on infrastructure like they do on everything else. >> i would echo what tim said as long as we had a prerequisite that congress couldn't punt on it. i think we need to do the same on existing federal properties, where we have excess and we've not consolidated. programs. we have workforce training an area that tim and i are both interested in. we did get through led by johnny isaacson last year that took federal programs from 48 to 36. i think we ought to be a lot smaller number. this notion of not doing it kind of in the big bang but an ongoing basis as long as you put a requirement that congress didn't completely punt and we're going to need these levels of efficiency. one that's kind of in the nerdy section, tim was helpful on this as well, we passed the data bill, data act to at least do financial system consolidation. there are 230 different financial reporting are systems and you wonder how we're going to provide accountability. tim and i both fought hard to get virginia best managed state because we put that attention on program efficiencies and management and oversight. opportunity to do more of that at the federal government level. >> this is also a future pass thing on the bases. the u.s. military, we've got bases everywhere, all over the world. china, bases outside of china? we're a greyhound and they are megabus. we have a lot of fixed infrastructure over the world and they are not doing bases. russia, big adversary, they have got presence in the ukraine sadly and they have a base in syria. they don't have bases outside the former soviet union. they don't. we have an unusual model that is probably overrelying on every real estate. >> i got a couple of questions from the audience. i appreciate the fact that your penmanship is a lot better than mine. i can read these. the first is what can we do to support the sustainability of one of our regions mo assets. that would be dulles international airport. >> we need, one, to continue to keep the pressure on which on getting rail to dulles. thank goodness that has been a bipartisan support for a long time and let's give an appropriate shout-out to frank wolfe through thick and thin and it's been harder to make that case, it was a great asset. we do need this -- this gets again into nitty-gritty but we operate reagan and dulles on separate balance sheets and candidly, they aught to be able to share some of their debt burden and that is a challenge, and one thing that tim and i have have been very strong on and you may want to take this because you said it brilliantly holding up the faa bill about not sticking more slots at reagan. >> this is a really important one. my father-in-law, many of you, lynnwood. he was hired by secretary dole during the reagan presidency to pull the two airports out of federal control and put them into the authority, and the whole reason for doing that is why does the federal government need to micromanagement these airports. let an authority with p independent bonding capacity manage the construction, manage where the flights are and congress decided to do it, but then congress had hardly decided to do it before it wants to micromanage but of course we want to fly it out of national at 4:30 on thursday afternoon so we can get back home. but congress has let it go but insisted on micromanaging and created a lot of slots out of reagan national and not let the airport manage t really fought against -- we have no fight it every year. it's usually very late working on transportation bills. are they going to try to screw around with the airports, looks fine. 11th hour, all these things come in to put a bunch more flights at reagan national which would hurt the finances out of dulles and we have to fight it off. >> we were both very successful this year. had a 16-month extension. no additional slots and again at the operational level one of the things we've worked on, we've built the corridor as an international gateway and we've been extraordinarily successful, thank you volkswagen and others for your presence here but then if we have two-hour lines in terms of immigration and tsa, we did get together 400 additional agents there and that is improved. >> yeah. shooting that somehow involved an off-duty d.c. police officer in northwest last night. police say the officer witnessed a shooting and intervened. the officer fired but police say they don't know if the officer shot anyone. it is under investigation. after being closed by power outages, all the museums on the mall will reopen today. outages began friday evening. crews were back out saturday morning and were able to get power running again. philadelphia is on high alert. one day before the democratic national convention begins, there's already a heavy police presence near the convention center as more than 10,000 demonstrators are expected. but first it's going to feel like triple digit temperatures today. good morning, i'm kristin wright. >> and i'm chris gordon. meteorologist tom kierein is start to warm up in our area. >> starting off on sunday morning, pretty pleasant right now, the humidity has dropped a little bit. you can see that in this live view from the storm team 4 tower camera overlooking washington where the visibility is not too bad. we can easily see the washington monument here in the distance behind the national cathedral. there's the potomac river under a hazy summer sky. near 80 by the bay and right downtown and later today it quickly jumps. temperatures by 10:00 will be in the upper 80s. mid 90s by 2:00. heat index around 100. a bit less humid through the afternoon and gets more humid tonight. upper 80s by 10:00 p.m. a look at how long this heat wave will last coming up this half hour. right now, the washington the national park service says a faulty bearing caused problems with the elevator saturday morning. we're told that depending on whether they can get the right parts, the monument will be closed until at least tuesday. today, a community will remember an alexandria man killed earlier this month. shaquan hall was shot on first street in early july. the suspect was arrested and is charged and awaiting extradition to alexandria. in prince george's county, police say they have found the car that was stolen in wednesday's deadly car jacking at a gas station in capitol heights. alonzo jackson had just filled up his black dodge charger. when a man shot him and drove off in his car. we learn that car was found abandoned and torched in the district. that's alonzo jackson a police chase starts in prince george's county and ends in a deadly crash in the district. d.c. police say a mount rainier city officer chased a suspect over the d.c. line saturday morning. during the chase, the suspect threw the gun out of car and slammed into a tree on michigan avenue in northeast. d.c. police performed cpr but the man died. it's not clear what started the chase. this morning, we're still working to learn the identity of the man struck and killed by a car friday night in capitol heights. he was walking along richy road about 10:00 p.m. the man was not in the crosswalk when the suv hit him. he was pronounced dead at the hospital cht the driver stayed on the scene. we finally learned the name of the pedestrian killed last week in langley park. 20-year-old a police cruiser hit him as he crossed the road. he was not in the crosswalk. it's another police shooting that has sparked outrage. a caregiver in florida shot and wounded with his hands in the air as we tried to help a man with autism. this morning, the autistic man's mother is talking about what happened. morgan radford has the latest. >> reporter: this is the man police thought was armed and suicidal. 26-year-old arnoldo rios, autistic and nonverbal. seen here with the toy truck before his therapist called for calm before being shot by an officer. her son is now in a psychiatric shot. she says he was handcuffed and held in a squad car for three hours. >> translator: my son is a human. not a piece of trash they said wiping away tears. arnoldo sister she's he's still upset and refuses to take off his shirt stained with his therapist's blood. >> says i took this job to save lives and help people. i did what i had to do in a split second. his commanding officer is on unpaid leave for giving conflicting accounts to investigators while they learn what happened. charles kinsey is recovering. >> i was more worried about him than myself because i'm -- as long as i got my hands up, they are not going to shoot me, leaving one man wounded and another deeply traumatized. morgan radford, nbc news new york. across the country and here at home, police departments are facing an increasing problem. hiring enough officers. in fact, d.c. has faced low staffing and recruitment levels for several years now. nbc's tom costello takes a look. [ sirens ] >> reporter: it's happening nationwide, police departments feeling under funded, under staffed, and under attack. in six years, the san jose police department has gone from 1,400 officers to 855. now just 18 recruits are in the academy. >> there's a lot of fear in law enforcement. there's a lot of fear with our officers families as well. we hire from the human race. people forget that our officers are human beings too. >> the biggest issue in jose, pay and pensions. now with police tactics under scrutiny, morale is sagging and fewer recruits are signing up. baltimore loss 6% following riots, detroit lost 5%. kathy lanier has been the washington police chief. >> we have been seeing that for some time now. >> nationwide, nearly half a million local officers wear a badge. the average salary $61,270, but much lower in many cities. just $46,000 in baton rouge where three officers were killed. $52,000 in kansas city, kansas, where two have died this year and $53,000 in dallas where five were gunned down this month. meanwhile, the demand on officers as only increased. >> there are more and more are being asked to deal with and quite frankly, we can't -- all the training in the world can't prepare for all of those issues. >> in all 32 officers have been killed by gunfire this year, up 68% over this time last year. with front line cops feeling under the microscope and under siege, top cost -- tom costello nbc news washington. isis is claiming responsible for an explosion that killed at least 60 people in afghanistan. on friday a man who police say was obsessed with mass shootings killed nine people in germany. three police officers killed in baton rouge louisiana, and more than 80 people killed in a truck attack in france. these are just some of the recent deadly attacks that have shocked our country and the entire world. so now the motivations for those attacks may have been different, but they shared a common thread and that's the killing of innocent people. last people in the community to march on the national mall against hate. the vigil was a multifaith event joining people from the muslim, christian, jewish and sikh religions. it was organized by american muslim groups to fight terrorism and violence. >> we're standing here because some people have said they have not heard us condemning terrorism. we would like them to hear us today. terrorism is not a religion. it's a cult. it destroys life and our religion promotes life. besides religious groups, there are also social organizations invited to the rally. there are new details about the teenage gunman who shot and killed nine people in munich, a search of the 18-year-old's apartment turned up documents on mass shootings and he didn't group. he also carried 300 rounds of ammunition with him when he began the rampage at a mcdonald's restaurant before he moved on to a shopping mall. the olympics athletes village opens officially today. the 31 building compound has over 10,000 rooms, 18,000 beds. seven laundries and a massive gym. organizers are also providing 450,000 condoms. that's three times more than london did four years ago. they say it's to encourage safe sex but many think the reason is because of brazil's outbreak of the zika virus. well, turn up the a.c. or hit the pool. tom is tracking some of the hottest temperatures we've seen all year, including a big impact tomorrow. maryland's race for governor could be shaping up. the candidate now being urged run against governorhogan in 2 good morning. the humidity levels have dropped a little bit so the heat index forecast for today, is not quite as bad address yesterday. definitely need to use caution. tomorrow, it will be dangerously hot and humid so the heat index up near 105 to 110 on monday afternoon, so near record heat on monday as well. it's going to be quite a steamy week coming up too. look at that, how long is this heat wave going to last just a couple of minutes. turning to decision 2016, tim kaine is making his positions clear now as hillary clinton's vp pick. >> his introduction was prt autobiography and part attack on donald trump. moderator chuck todd is live in philadelphia this morning ahead of the good morning. was his introduction, was it effective and what can we expect going forward from the clinton-kain ticket? >> i thought the rollout as good than i've seen in a long time. it was certainly a lot more put together than donald trump did for mike pence. there appears to be genuine chemistry between hillary clinton and tim kaine. tim kaine showed off his ability to go back and forth from english and spanish. that was the whole point. the minute she decided on tim kaine, they decided the roll-out would be in florida to showcase his ability to speak two languages, including spanish which is so important in contacting hispanic voters. i think it went well. i think it's one that you can see how they are going to deploy him. but let's remember this. the two days get a lot of attention, the day they are rolled out and you don't hear from them again until the debate. that wouldn't shock me between tim kaine and mike pence. >> what are they trying to accomplish this week? >> i think they have a mini crisis if you are a clinton campaign. this wikileaks release of hacked emails out of the dnc, there's some uncomfortable email from the dnc that seem to add more evidence to the pile of accusations that bernie sanders supporters have been making for months that the dnc wasn't being a fair umpire during the democratic primary and these leaked emails seem to fuel those charges and i have to tell you it's not the way for this thing to kick off if you are hillary clinton. we already have heard one recripple nation, debbie wasserman schultz. we'll see if that's enough. >> a lot to talk about. we'll see you this morning, "meet the press" after our show at 10:30 here on news 4. former maryland attorney general doug gasler says he's being urged to run against republican governor larry hogan in 2018. he says that democrats want the most viable candidate to beat hogan. he says he is not organizing any campaign right now. he lost to then lieutenant governor anthony brown in the 2014 democratic primary and of course, brown, went on to lose to hogan in the general election. we want to thank all of you who adopted a pet our nbc4 clear more than 1,400 animals in our area now have forever homes. news 4 wendy rieger reports. >> is she going home with you guys? >> yes. thank you. thank you. thank you. >> this woman and her kids were among the hundreds who came to shelters to find a new family member and there were plenty of animals to shoot from. almost 200 dogs and cats at the washington humane society, washington animal rescue league alone and people braved the sun and heat to get in line early. >> we lost our cat george a couple months ago to kidney disease and there's been a hole in our house sense. >> there are plenty of cats to choose from. more cats than dogs. >> what are you? >> but sheryl lewis came that number. sheryl was looking to get two of the kittens we featured on the air. most of the people went home with their pets ready to start a new life. we want to point out what a great job wendy did yesterday interviewing those animals. i forgot his name. what's your name? woof-woof. >> she did a phenomenal job and all of you did a great job taking home these dogs and cats. wendy mentioning braving the heat and humidity to do that. temperatures right now are pleasant but we have a weather alert day under way again today and it's going to continue. the weather alert into monday and tuesday as well with excessive heat. there's that sun already jumping up in this july sky on this sunday morning. live view from the storm team 4 tower camera. we're in the 70s, any from the shenandoah valley to the bay. low 70s, nearby suburbs, near 80 as well right around the chesapeake bay. by 10:00 it will be getting hot. it will be in the upper 80s and i by 2:00, mid 90s, 4:00, 5:00, up 90s. and then by 10:00, back down to the upper 80s. to a warm and muggy evening as the humidity is going to crank right back in this morning. storm team 4 radar don't have any showers or storms anywhere in our region. these areas of color here, maybe a few potential showers and thundershowers, panhandle of west virginia, shenandoah valley between 3:00 and 6:00 p.m., south and east, they dissipate, a few clouds around this afternoon. overnight, they will all be gone. the humidity cranks right back wave

continents. and the panama canal, that made our world a smaller place. we backed the marshall plan that helped europe regain its strength. and pioneered the atm, for cash, anytime. for over two
