Be still my soul reporter as las vegas continues to heal, the motive behind this senseless tragedy is still unclear. And the city is trying to get back to normal, matt, but there is a feeling that everything has changed here. We will will send it back to you for now. Thank you, savannah. For more on the investigation, we go to nbc justice correspondent pete williams. Pete, savannah said that the motive is still unknown, and is this investigation now going in any specific direction and are they focusing on anything in particular . Yes, the direction is mostly backwards, and what they are trying to figure out is backwards from the moment of the shooting and they have found some disturbing things. They told us that the weekend of the shooting paddock had rented room s rooms in this highrise in a condo building that overlooked the big as light music festival, and wondered if that is a dry run. And then looking at the time line of buying shotguns and handguns in utah, texas and california and atf says he bought most of them within the last year. They are looking hard at the finances, the gambling, and the spending and the money he wired overseas, and they want to know if he was in some kind of financial trouble. And when you go back to the kocondominium that he rented, i there any surveillance showing that he brought the same suitcase s suitcases to the location, and might have had weapons with him at this time . That is something they want to pursue. They have a ton of Surveillance Video to go through, and it is a long complicated process, and they dont have the answer to that question, matt. And searches of the location, and they have searched a couple of home, and the hotel room, and where does that stand, is that over . The hotel room is not over, and they say it is going to be taking several days, but the search of the homes and the cars and the storage unit is done as well, and they have not found any answer to why. No manifesto or video statement or anything to explain what he did. But in some ways the most important searches are still going on now sh, the Electronic Devices that he had, the phones, and the tablet and the computers, and they hope to find some answers there. And anything, before i let you go, anything more on the explosive compounds found in particular in that automobile . Well, that is a real poser, because one of the cars did have Ammonium Nitrate in the trunk which is a fertilizer, but we looked at the aerial pictures of the houses in nevada, and neither of them has a lawn. And Ammonium Nitrate can be used to make explosives, and that is Something Else that law enfor enforcement is looking for and they are hoping for the the girlfriend to answer some of the questions. And they are questioning her now. Thank you, pete williams. Back out to savannah. All right. Matt, as we mentioned at the top, the president is traveling here to las vegas today on the heels of his visit from another place dealing with a horrific situation, puerto rico. And Kristen Welker has traveled her. Yes, all eyes are going to be on President Trumps visit today in the hours after the shooting, and the president referred to it as an act of pure evil, now he will have the chance to witness the aftermath firsthand. He is is going the be meeting with the survivors in hospitas s as well as First Responders. It is a major test for the president who is now dealing with two major disasters at the same time. Reporter President Trump speaking out this morning before leaving for las vegas. We are going to the pay our respects and to see the police who have done really a fantastic job in a short time. It is a very, very sad day for me personally. Reporter aiming to provide comfort to a community ripped by grief after sundays mass shooting. We will be paying our personal respects and 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. On air force one overnight, President Trump insisting that he heard no criticism while on the ground. We totally heard thank yous from the people of puerto rico. But the mayor saw it differently. He was insulting. The mayor and he have been quarrelling on the federal response. But when they shook hands, it seemed a temporary truce. It is not about politics, but about saving lives. Reporter and then he made no mention of the governor. This governor did not play politics at all. He was saying it like it was and giving us the highest rating. Reporter and he joked about how the disaster costs. And i hate to tell you, puerto rico, but you are throw ing the budget out of whack. Reporter and he claimed that there was a much lower death toll as that in katrina. If you are look at a death toll of katrina and the hundreds of people who died and 16 people versus in the thousands, you can be very proud. Reporter the mayor of san juan lashing out. He has a communication issue, and he is sort of 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 it all capped a day of president ial outreach, and President Trump meeting families struggling to rebuild and tossing out pay p paper towels basketballs. And he insisted that he is going to be talking about the victims and not gun control. We will talk about gun laws as time goes by. Reporter we want to point out that the death toll in Puerto Rico Rose to 34 overnight, and more than twice the number cited by President Trump yesterday. The president is tweeting about the visit this morning saying that a great day in puerto rico yesterday, and while most of the news is fake, it was warmth and friendship. So in all, we expect him to be on the ground for four hours today, and it is going to be an emotional day. Yes, a lot of people hurting here today, kristen. Thank you very much. Matt, we will share some of the dramatic stories of heroism and survival here. But for now, we send it back to you. A lot more the get to, including a situation in the white house of what appears to be a deepening riff between the president and the secretary of state Rex Tillerson. Andrea mitchell is here with latest on that. Good morning to you. Indeed, matt. And the u. S. Officials are denying a split between the president and the top diplomat over north korea after the president e president s tweets undercut the secretarys outreach to north korea a day earlier, and according to the nbc news, this incident is capping months of friction of the president and tillerson which almost led to the top diplomat resigning in ju july. This morning, more signs that the troubled relationship between President Trump and the secretary of state is reaching a boiling point. A growing course of headlines calling for Rex Tillerson to quit after the president attacked his outreach for north korea. Save your energy, rex. We will do what has to be done. I told Rex Tillerson our secretary of state that he is e sting his time to negoatti with little rocket man. That that bombshell coming just seven hours after tillersons arrival home from china. And he said, we do talk to them through our back channels. Tillersons diplomacy is pleasing to china, but not boss back home. And multiple white house officials tell us that tillerson was already on the outs for the president for refusing to tear up the iran nuclear deal, and pointedly disagreeing with President Trumps controversial comments about the deadly unrest in charlottesville. The president speaks for himself. For his part, tillerson was frustrate frustrated when the president sided with saudi arabia against a key u. S. A ally qatar, and Officials Say that the final blow for the secretary of state a former leader of the boy scouts came in july when the president gave a widely political speech to the scouts. We would go to wisconsin and we had tremendous crowds. Current and former officials tell care ra lee that tillerson tried to quit but talked out of bit allies including the secreta secretary of state general mattis and Vice President mike pence who had to give tillerson what is described as a pep talk to tell him to get on board with the president. The secretary mattis is trying to play down the riff between the president and tillerson, and top tillerson aide denies that the secretary was going to try to quit or offended by the president s speech to the boy scouts. A top aide said that he will stay in the cabinet for as long as the president wants him to serve, but many say that nikki haley is campaigning for it. And this not a squabble between the boss and the employee, but it is the president of the United States and the secretary of the state given all that is going on in the world right now, can Rex Tillerson carry on diplomacy while he is being undercut in this manner . Well, that is the big question, because the stakes are enormous, and look at north korea, taand the fact that kim jongun and the leaders of president xi in china are confuse who is in charge, and they know that it is the president , and tillerson does not speak for him, and that is dangerous around the world. And to give an idea, carol of 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. Okay. I will set the scene for you, at a meeting with the pentagon and the president s National Security team and cabinet officials, the white house officials, and the president attended and left and the group was gathering and a number of people around and the secretary called the president a moron. In front of all of those people. And he said it loudly enough for a number of people to say, yes. Is the president of the United States aware that happened or was he aware prior to right now . A good question. It is unclear if he was aware, but sources tell us that no family members were around, so it is unlike ly that anybody tod him. And andrea, why is tillerson still there and given all of this, why has he not handed in the resignation . He is a proud man and he wants to accomplish something, and downsizing the state department and eliminating waste and he wants to wait for the management review, but the frustrations are mounting, and if he feels that he cannot accomplish anything especially since he has lost the confidence of the department with his budget cuts and the lost the confidence of capitol hill, he could leave at any time. Andrea mitchell and carol lee, appreciate it. New developments this morning in a mystery fueling are renewed tension between the United States and cuba. The u. S. State department is now expelling 15 cuban diplomats from the country. This is coming in response to the mysterious sonic attacks that sickened american officials at the u. S. Embassy in havana. The unexplained attacks dating back to late last year led to 22 american diplomats and family memb members with symptoms of headaches, memory loss, and secretary tillerson says that we continue to maintain diplomatic relations with cuba and we will will continue to cooperate with cuba as we pursue the investigation into the attacks.
