Pete, what is the focus of the investigation right now . They are trying to trace his movements. Working back from the shooting. And they found disturbing things. The weekend before the shooting, paddock rented rooms in a highrise condo in las vegas. That overlooked the life is beautiful festival. They want to know if that was a dry run. And theyre looking at the gun purchases. He bought rifles, shotguns and handguns in utah, nevada and california. They are looking at his gambling. They want to know if he was in financial trouble, matt. Have they completed their searches . Have they finished searching everything or everywhere he was lately . For the most part. It will take a couple of days to finish going meticulously the hotel room. And also a storage unit. They found no manifesto, no video statement, nothing to explain what he did. The important searches is all of the Electronic Devices in the hotel and his houses. They hope they will contain some record of communication that can shed some light on his motive. Weve been hearing about explosives or explosive materials found in his car or in his house. Do you have anything on that . Thats not question they cant answer right now. One of the cars, the one at mandalay bay, has Ammonium Nitrate in the trunk. We looked at his houses. And neither one of those have a lawn. Ammonium nitrate can be used to make explosives. They are hoping his girlfriend can provide answers to many of the mysteries. They will be questioning her closely, matt. All right, pete williams. Thank you very much. Lets go back to savannah.

In just a few hours, President Trump will touch down in las vegas, aiming to provide comfort to a community gripped by grief, after sundays mass shooting. We will be paying our personal respects and condolence to condolences to everybody. What happened is such a tragedy. Reporter it comes on the heels of his tuesday visit to another scene of devastation, puerto rico. An air force one overnight, mr. Trump insisting he heard no criticism while he was on the ground. We only heard thank yous from people of puerto rico. Reporter but the mayor of san juan saw it differently. He was insulting to the people of puerto rico. Reporter the mayor and the president have been feuding for days. On tuesday, when the two shook hands, it seemed there was a temporary truce. Its not about politics. Reporter but moments later, the president praised puerto ricos governor, while making no mention of the mayor. This governor did not play politics. He didnt play it at all. He was saying it like it was. He was giving us the highest grades. Reporter mr. Trump joked about how much the disaster will cost. I hate to tell you, puerto rico, but youve thrown our budget out of whack. Reporter the president congratulating puerto rico for having a lower death toll than hurricane katrina, which claimed 1,800 lives in 2005. You look at a real catastrophe like katrina, and you look at the hundreds and hundreds of people that died. 16 people instead of thousands. You can be proud. He has a communication issue. Hes like miscommunicator in chief. Reporter angry words from washington, too. Mr. President , enough. Stop blaming puerto rico for the storm that devastated their shores. Reporter ill out capped a day of president ial outreach. Mr. Trump, meeting with families struggling to rebuild. At one point, tossing out rolls of paper towels like basketballs. Today, the tone in las vegas is expected to be more somber, with the president signaling he will be talking about strivictims, n gun control. Well talk about gun laws as time goes by. Reporter it is important to point out the death toll in puerto rico overnight has risen to 34, more than twice that number cited by the president yesterday. Mr. Trump is tweeting this morning about all of this. Saying, a great day in puerto rico yesterday. While some of the News Coverage is fake, most showed great warmth and friendship. He will be here on the ground in las vegas for about four hours, savannah. He will meet some people that need comfort and love. We have new stories of survival and heroism that unfolded here. We want to share that with you. For the moment, matt, back to you. All right, savannah. A lot to get to, including a situation facing the white house. What appears to be a deepening rift between the president and his secretary of state Rex Tillerson. Andrea mitchell is here with that. Reporter the state Department Officials denying a split between the president and his top diplomat, over north korea, after the president s tweets undercut the secretary of states outreach to korea just a day earlier. And the latest incident caps months of friction between the president and tillerson, that almost led to the top diplomat resigning in july. Many morning, more signs the troubled relationship between President Trump and his secretary of state is reaching a boiling point. A growing chorus of headlines calling for tillerson to quit, swe tweeting sunday, save your energy, rex, we will do what needs to be done. I told Rex Tillerson, our secretary of state, that he is wasting his time trying to negotiate with little rocket man. That bombshell from the president , coming seven hours after tillersons arrival home from beijing, where he revealed that the u. S. Has a back channel to north korea. Telling reporters in china, we can talk to them, we do talk to them, directly, through our own channels. Tillersons efforts pleasing his hosts in china. But not the boss back home. Multiple white house officials tell nbc news, tillerson was on the outs for the president , for refusing to tear up the Iran Nuclear Deal and disagreeing with mr. Trumps comments about the deadly unrest in charlottesville. I think theres blame on both sides. The president speaks for himself. Reporter tillerson was frustrated when the president sided with saudi arabia, against a key u. S. Military ally, qatar. The final blow for the secretary of state, a former leader for the boy scouts, almost came back in july, when the president gave a widely criticized political speech to the scouts. We go to wisconsin and we had tremendous crowds. Reporter current and former officials tell nbc news carol lee, tillerson was ready to quit. But he was talked out of it by james mattis, john kelly and mike pence, who had to give tillerson what is described as a pep talk, telling him to get onboard with the president. Service secretary mattis is trying to play down the rift. And a top tillerson aide denied the secretary tried to quit or was offended by the president s speech to the boy scout scouts. As for how long he will stay in the cabinet, a top aide said, as long as the president wants him to serve. But nikki haley is widely viewed as auditioning to replace him. All right, andrea. Were joined by political reporter, carol lee. This isnt just a squabble between a boss and an employee. This is the president of the United States and the secretary of state. Given all thats going on in the world, can Rex Tillerson carry on diplomacy while hes being undercut in this manner . Thats the big question. The stakes are enormous. Look at north korea and the fact that kim jongun and president xi in china are confused who is in charge. They know its the president and that tillerson does not speak for him. And that is really dangerous around the world. To give an idea where this has all gone. You have reporting that suggests that Rex Tillerson, following a National Security meeting, used a derogatory term to describe the president. Take me further. Ill set the scene for you. It was at a meeting with the president s National Security team. Cabinet officials, white house officials, the president attended. He left. The group was gathering. There were a number of people around, and the secretary called the president a moron. In front of all those people . He said it loudly enough for a number of people to hear him say that, yes. Is the president of the United States aware that that happened . Or was he aware prior to right now . A good question. Its unclear if he was aware. But sources tell us that no family members were around. So, its unlikely that anybody told him. Andrea, real quickly, why is tillerson still there . Given all this, why hasnt he handed in his regular natisigna . Hes a proud man. Its the eliminating waste as he sees. I think the frustrations are mounting. If he feels that he cannot accomplish anything, especially since hes lost the confidence of the department with his budget cuts, he could leave at any time. Andrea mitchell, carol lee, thank you very much. Theres new developments in a mystery thats fueling renewed tension between the United States and cuba. The u. S. State department is expelling 15 cuban diplomats from the country. This comes in response to the mysterious sonic attacks that sickened officials at the u. S. Embassy in havana. The unexplained attacks led to 22 diplomats and family members with symptoms including headaches, hearing loss and memory loss. Secretary tillerson says we continue to remain diplomatic relations with cuba. We will cooperate with cuba as we continue the investigation into these attacks. Al is here with the weather. Mr. Roker . This is a perfect example of all of the weather affected. The gorgeous weather in the northeast, is affecting whats happening in the southeast. Heavy rain from florida to the bahamas. A big area of high pressure. Its not going anywhere. And its slingshoting all this wind across florida. So, its a strong onshore flow. We have aboveaverage tides.
