Largest vigil yet for the victims of the pulse nightclub shooting as the fbi prepares to release the gunmans calls with hostage negotiators. And risky rescue. One, perhaps two, workers sick and stranded at the south pole. Conditions so far making it impossible to reach them as crews wait and hope for a break in the weather and a chance to save them today, monday, june 20, 2016. Announcer from nbc news, this today with matt lauer and savannah guthrie, live from studio 1a in rockefeller plaza. And good morning, everybody. Welcome to today on a monday morning. Weve got willie in for matt. If youre a little blurryeyed, willie, i understand. You stayed up to watch history. Lebron james brought that title to cleveland. He grew up in the state of ohio. He brought a couple to miami but this one meant the most in his state of ohio. The city of cleveland has not won since 1964. Miguel almaguer is in oakland, california. Thats where history unfolded, and the cheers of cavs fans can still be heard. Miguel, good morning. Reporter savannah, matt, good morning. A hardfought series all the way to the very end. This morning here in oakland, disappointment, while in cleveland, history. Announcer oracle arena is alive and roaring. Reporter the showdown wasie electrifying. Game 7 down to the wire. Two of the games best, lebron james going head to head and literally face to face. The two of them have some words. Reporter the heated series, a classic. The final game a seesaw battle. Announcer lebron james another attack at the basket. Reporter with the score tied and a minute left, khyri irving would drain a three, giving the cavs the lead and ultimately the title. For cleveland, their first championship in franchise history. Announcer the cavaliers are nba champions. Reporter for james, who left the cavs six years ago as a villain, hes returned a Hometown Hero. I gave everything i had. I put my heart, my blood, my sweat, my tears to this game, and against all odds, cleveland this is for you reporter cleveland, the first team in history to rally back from a 31 deficit in the finals. The warriors were the first team to win a record 73 regular season games. We had a great regular season. This is something no team has ever done before. Fell short in the last game of the season. It hurts, man. Reporter in the cavs locker room, champagne and tears on fathers day. Everything i do is for my parents and my family. The cars are nice, the houses are nice, but none of this matters without them. Reporter in the streets of cleveland, an allout, allnight party. Man, that parade is going to be ridiculous. Reporter the celebration has just begun. This is history. The cavs are champions. The city of cleveland hasnt won a major sporting championship since the 1960s when the Cleveland Browns won the nfl title. Lebron james was the series mvp. As for the league mvp, sharpshooter steph curry. He said his league will be back next year. The warriors were 739 in the regular season, they were up 31 in the series. The Cleveland Cavaliers just won three consecutive games against the best team in nba history. Heard that on the radio this morning. Well done, well done. Well talk more about that game coming up later. Also this morning, recordbreaking heat. Its intensifying in the southeast. The triple digit temperatures making the fight against raging wildfires even more difficult. Nbcs Steve Patterson has the latest. Steve, good morning. Reporter good morning, willie. This area under a red flag advisory with officials saying fire activity here could increase. Meanwhile, these tripledigit temperatures we are feeling all across the southwest are only going to get worse. This morning the southwest ravaged, destructive flames, and deadly recordsetting heat. The wildfires scattered all over the map. In arizona, the cedar fire driven by low humidity and blistering temperatures over the weekend has torched more than 12,000 acres. In new mexico, life altering. Its terrifying. Its just like you cant imagine, and you just want to run. Reporter two dozen homes destroyed in the wake of the doghead fire, a 17acre monster thats been hard for firefighters to contain. In santa brash ra, 2,000 firefighters are battling the sherpa fire. Sundowner winds, powerful santa ana winds that pick up around sunset have blackened many acres, turning it to ash. But now its the heat crews are most worried about. Sunday three firefighters had to be airlifted for heatrelated emergencies. We have started to see some of the effects of this hot weather and the impacts its having on our firefighters. Reporter that hot weather having an impact everywhere. 104 degrees at chino hills in this soccer tournament. Reporter excessive heat warnings throughout the southwest. Officials in california issuing a flex alert, urging residents to conserve energy to avoid Power Outages and protect themselves from heat stroke. In arizona, the extreme heat is fatal. This is incomparable to anywhere else. Reporter a tragic warning as to how dangerous this heat can be. In an example of this extreme heat, a United Express flight from houston to phoenix had to be diverted because of those record temperatures in arizona. Sometimes the heat can compromise the lift of a planes wings and the thrust of its engine. Its striking to think about how this heat can affect something even science based, willie and savannah. Those conditions not helping, either. We have dillon in for alan. Tell us theres relief coming. I dont think well break any records, but it will be exceptionally hot with temperatures around 115 degrees. We have 29 Million People under some sort of heat alert in the southwest, but keep in mind there are 110 Million People who will see temperatures above 90 degrees across the entire country. So it is hot everywhere. But lets take a look at whats going on where temperatures will be 100 to 125 degrees. This, of course, leads to dehydration, especially because humidity is so low so you need to stay hydrated and check on your neighbors and make sure everyone is safe in this kind of heat. We are looking at the heat to continue over the next several days, again, because of this area of high pressure. You have this sinking air, and as the air sinks, it heats up. We are looking for temperatures to remain at about 15 to 25 degrees above average. Los angeles about 104 degrees. As we go through the middle of the week, well see temperatures drop off a little bit in burbank, but still in las vegas, through yuma, through phoenix, temperatures maybe not breaking records but still up around 115 degrees, which is very dangerous. The good news for firefighters in santa barbara, temperatures should drop to the 80s and we should see an increase on wednesday. Lets turn now to the orlando nightclub massacre. Thousands of people attended a massive vigil one week after the worst mass shooting in u. S. History. Today officials will release new information on what the gunman said to police during the rampage. Gabe gutierrez is in orlando. Gabe, good morning. Reporter good morning. Later today the fbi is expected to release partial. Translator transcripts of the calls he made. All this as the community bounces back, honoring the victims in the largest gathering yet. Late sunday a massive vigil in orlando joined tens of thousands to focus not on the killer, but the victims. I think its brought us together in ways unlike anything before. There is a lot more that puts us together than what divides us. I think you see that. I never imagined. I cant describe that. Reporter oscar was just 26, a mentor to his younger brother. His dad held his funeral on fathers day. I prefer to die first. I prefer to give my life for his life. Reporter this morning federal investigators are Digging Deeper into the orlando gunmans motive. As this newly released propaganda video praises omar mateen for the massacre at the pulse nightclub. It does not indicate he had any prior contact with isis. Where we are in this investigation is talking to everyone who had any kind of contact with this killer. Reporter on meet the press, attorney general Loretta Lynch would not say whether mateens wife might face charges. A senior Law Enforcement official tells nbc news they found so far no manifesto or anything resembling a suicide note. That indicates there is some indication he may have used dating web sites, though they have not found dating apps on his cell phone. Back at sunday nights vigil, amid the sorrow, suddenly, a sign of hope. Its helped galvanized people to realize what is important. The city will not be defeated. Reporter it really was a powerful sight. Since the rampage, more than 7 million in donations have been raised for the victims. She plans to visit tomorrow with investigators. A new political fallout from the orlando shootout as well. Donald trump weighing in once again and also speaking out about some cracks in his support within the Republican Party. Nbc National CorrespondentPeter Alexander is following that story. Peter, good morning. Hi, savannah, theyre actually brewing signs of rebellion against donald trump within the Republican Party as we reveal newly unveiled plans to try to stop his nomination among delegates to next months convention. Its a long shot. The rnc says it will never happen. As far as party unity, he still has a big climb ahead. Donald trump renewing his call for the u. S. To consider profiling muslim to see avoid another terrorist attack. I hate the idea of profiling, but we have to use common sense. Reporter hes facing a wide deficit against hillary clinton, trailing in polls and in money. Still insisting its early with nbcs hallie jackson. Looking to capitalize, clinton and her democratic allies are releasing 23 billion worth of ads in battleground states. Protrump forces havent spent a dime. This weekend he was playing catchup in the fundraising battle, making stops in texas, a red state, but hasnt voted democratic in 40 years. If the gop doesnt want to help pay his way, trump says hell do it himself. Well have to have help. Well have to have help. Otherwise ill keep doing what im doing, ill keep funding my own campaign. Reporter with trumps wounds largely inflicted. Paul ryan is giving republicans the green light to vote how they choose. The last thing i would do is tell somebody to do something against their conscience. It would be nice if the republicans stuck together. I think i win either way. I can win one way or the other. Reporter with Vice President joe biden expected to unload today, its open season on trump for democrats. Every day it becomes clearer that he is a thinskinned, racist bully. And every day it becomes clearer he will never be president of the united states. Reporter still, trump says hes sitting pretty. I feel lukeike a supermodel except times ten. Its true. Reporter a little joyful news this weekend, too. Hell be too young to vote this fall, but the Clinton Family is celebrating a new addition. Chelsea clinton giving birth to a new grandson. His name is aidan. Hillary clinton tweeting, what a joy being with our new grandson, so grateful. Signed, h. Congrats to them, but back to this gun debate. I know there are votes on the hill today, peter . Thats exactly right. This has become a familiar pattern. The last time the senate held votes on gun reform was last september. Proposals then failed. Another four up for a vote today, two sponsored by democrats, two by republicans. It seems unlikely either of them will pass, either. Simply put you have both competing on measures of background checks and people on a terrorist watch list. Even that with divisions with republicans worried about fringing on someones due process if theyre wrongly on that list. They hammered lawmakers that given this threat of terror that these new efforts are basically useless. What were doing with this debate on the hill right now, its like theyre trying to stop a Freight Train with a piece of kleenex. The bills all need 60 votes to pass. That means for anything to change here in washington, savannah, its going to have to be bipartisan. Donald trump actually did weigh in on this, and it seems like he might be willing to take on the nra and side with this notion of no fly, no buy. I think thats right. This weekend he focused his remarks on how to keep the country safe, but he found himself at odds with the nra. Trump argued that if more people at that orlando nightclub were armed with guns strapped to their waist and if they fired back at the shooter, the carnage would have been much less. But even the nra pushed back against that, insisting it does not believe people should be carrying guns in drinking establishments. Trump has said he would meet with the nra suggesting he was on board with the law to try to keep guns out of the hands of people already banned from flying because theyre suspended or they are known terrorists. Savannah . A lot of moving pieces in politics today. Peter, thank you. Speaking of guns, a connecticut judge will hear arguments on whether a lawsuit can continue against the semiautomatic rifle used in the sandy hook shooting. Families of victims are suing Remington Arms which made the ar15 style rifle used in that attack. The plaintiffs say the company knew the rifle was meant for the military and too dangerous to sell to civilians. Remingtons lawyers argue the lawsuit is barred by federal law that shields gun manufacturers from most lawsuits over criminal use of their products. A funeral will be held tomorrow for the twoyearold boy who was killed by an alligator at disney world. This as more changes with being made at the park with this tragedy. Kerry is following that for us in new york. Kerry, good morning. Reporter savannah, its been almost a week since twoyearold lane graves was killed and attacked by an alligator here at disney world. This morning his parents and fouryearold sister are back in nebraska, preparing to lay him to rest. This morning the beach where lane graves was snatched by an alligator and dragged to his death remains closed. After capturing what may be all the wild alligators that were in the waterways here, disney added these temporary barriers. New signs are up, too, warning guests alligators and snakes can be dangerous. Disney saying its safety team, along with its animal behavior experts, are working on a longterm solution, evaluating what procedures need to change, while recognizing alligators are a fact of life in florida. Last tuesday evening, twoyearold lane graves was playing in Shallow Water in the lagoon with his dad by his side. The alligator attacked just after sundown when gators usually hunt. The medical examiner says the toddler died from drowning and traumatic injuries. Lanes father, releasing this emotional statement. Melissa and i continue to deal with the loss of our beloved boy lane and are overwhelmed with the support and love weve received from family and friends in our community as well as from around the country. We ask for and appreciate the privacy we need to lay our son to rest. At the familys hometown in nebraska, neighbors are showing support. Thank you. God bless you. Reporter collecting donations we ask this for your son holding prayer services, tying blue rib bones outside the graves home. They were just trying to make memories for lane and noah. It just breaks my heart she has to go through this. A wake for lane graves will be held later today. His funeral is scheduled for tomorrow. Lets go back to some sports now. American Dustin Johnson overcame a controversial onestroke pemt penalty to win the u. S. Open sunday. As johnson was beginning to putt, his ball moved just a bit. He told the official his club never touched the ball. Still, later in the round while he was still playing and trying to win the u. S. Open, he was told that he may later be penalized for it. That created a firestorm on social media against the usga who told johnson that. Despite the debate, johnson finished four strokes ahead of the field, so the onestroke penalty in the end proved to be irrelevant. He won the 1. 8 million prize. He is one of those never to win a major and he finally got it yesterday. Was the controversy under a cloud that he had to be potentially distracted by the penalty . At a major on a sunday, you get that in your head that you have to be one stroke better. A fly around his head. Never let em see you sweat, right . He won by four. Lets get to the forecast. Its hot pretty much everywhere around the count, except for the northeast and the northwest where the temperatures will be decent. From the interior northeast to parts of ohio and indiana, too.
