Both address ed to joe biden, another one sent to the production offices of Robert De Niro here in new york city and another sent to Maxine Waters in los angeles among many others. We still have to idea who did this and the fbi wrapped up a joint press conference in new york a short time ago. Warning that more devices could still be out there. Remain vigilant as it does remain possible further packages have been or could be mailed. Do not move, do not handle any suspicious or unknown package. Leave it to the Law Enforcement professionals. Nbc chief Investigative ReporterJonathan Dietz is reporting that authorities believe some of the packages were mailed from florida. Investigators want to know if theres a potential connection to prior threats made directly to florida congressman Debbie Wasserman schultzs office. Some were poorly made. Investigators are trying to determine whether or not that means this was a hoax or the work of an unsophisticate bomb maker. Also theres been speculation that some of the devices including the ones sent to george soros home were hand delivered because they lacked postmarks. But they did go through the mail. The soft packaging couldnt go through the machines and those postmarks didnt et show up. In addition to the investigation, we are following a dramatic series of Political Developments tied to the story as the president and allies point fingers at democrats and the media for the current toxic political environment while deflecting any comments directed at them. The president claim ed that the anger in this country is because the Mainstream Media purposely reports false news. He said the media needs to, quote, clean up its act fast, but he only targeted Mainstream Media and not his echo chamber. And Sarah Sanders told reporters that the press has a role to play in this issue. But she seemed to bristle at the idea that the president does too. 90 of the Media Attention around this president is negative despite historic job creation, despite the fact that our economy is booming. You guys continue to focus only on the negative. That is a role to play. Does he acknowledge he has a direct role to play . Theres a big difference between comments made and actions taken. The president is not responsible for sending suspicion packages to someone no more than Bernie Sanders was responsible for a supporter of his shooting up a baseball field practice. This is at the hands of the president is ridiculous. Were going to dive into the political fallout in a moment. Were going to give with the the latest on the investigation. Pete williams is our justice correspondent here at nbc news. Jim kavanaugh is an msnbc contributor. And Clint Van Zandt is a former fbi agent and profiler. You were so helpful yesterday in understanding this. We brought you back today for more of your insight, more of your help and helping viewers understand this. Pete, let me start with the investigation itself. We heard that press conference. Do they really have no idea who it is or theres a group of people that they suspect but they are not ready to talk about it publicly . I think its more the former than the latter. They dont have a suspect at this point, but there are some helpful signs. Theres some indication base on analysis of the packages that at least some of them were postm k postmarked. Youre right about the soft packaging and the odd size of the packages with the bombs stuffed into the envelopes so they didnt go through automatic canceling machines. So some of them that went to cnn were not cancelled or otherwise stamped. But some were, according to people who have seen images of all the bombs and that has in part led them to the possibility that at least some of these devices may have been mailed from florida. So they are pursuing that. But they want to try to find out is whats the last post office that handled them and then try to work back to figure out where did they originate, whats the closest post office to the point of origin and get Surveillance Video in trying to figure out whether anybody saw them and look at witnesses and that kind of thing. Thats a hopeful sign. In a bombing investigation, usually investigators are crawling around picking up little pieces. Here you have nine fully intact devices. Thats an unbelievable evidence wind falls that they will try to exploit from all the pieces, all the components that went into the bombs and also trying to find any evidence that was inadvertently left in the packaging. So they have a lot to work with here. Has a single envelope been opened . Was it opened or has every one of these i us ask because is there an obvious trigger . How is this bomb supposed to fwo off . None of them went off. How is this t supposed to go off . Thats a good question. What were told is often times package bombs are designed to go off when they are opened. For example, that was the mo of the unibomber. Those were rigged to go off and those were largely boxes and envet low. S. They havent seen any wires coming out of the devices attached to the envelope that would be a make or break circuit to set the bomb off. So one question is what was supposed to set the bomb off. We think the gadgets taped to the side of them, the electric circuits you have seen, that thing in the fore ground there is some kind of timer. But for what . A timer to set it off at some time . How do you do that with a package bomb . You dont know when its going to be delivered. Was it to keep it from going off until a certain point. So thats good question and i dont think we know the answer to that. It feels if were talking about a timer was this an inexperienced bomb maker or somebody overly sophisticated maybe on technology, but under sfophisticated on explosives. I will tell you that they dont know the answer to that. They dont know who made them. Its hard to know what the et design philosophy was. I will say that they believe that some of these devices after analyzing them initially would not have gone off. Because there are flaws in the way they were made. But is that intention al to be scary hoax device or because they simply didnt et know what they were doing. And i hope you pursue that question with Jim Kavanaugh because we have talked about this and he had some views on that. But they just dont know what the deal is. And they have to be very careful to say two things. One, they havent analyzed all these in detail yet. Its a slow, painstaking process because they are trying to disaemable and preserve every piece of evidence they can get. Any fingerprints along the way so its a very slow process. But secondly, they want people to know that these are potentially dangerous. Just because none have gone off so far doesnt mean if you find another one it might not be the one that works and you should treat it carefully. Is it precaution they warn there might be. More or is this an assumption or do they have evidence . No evidence that there are anymore. The Postal Service person at the News Conference said they know of none in the system. The secret service has said they dont et know of any against their protectees. The one that was for dinero was sitting in the office for two days before they realized they had it. But they dont know of any that are out there. They have to assume there could be, but they dont know. Pete williams, i will let you go. You have a lot of work to do. So thank you. Pete, you did tee up Jim Kavanaugh. When i us moderate debates, i go to the next person name checked. I guess this is a bit of a mystery. We cant figure you how these bombs are supposed to go off. What does that say to you . It says one thing. This bomber was not the valedictorian of the bomb making which is a. They may be. Just poorly made and designed desivices. I can tell by looking at it there are a lot of flaws, which i wont talk about on the news because we dont want to educate the guy. But theres certainly some flaw this is there. So they could have been made heres the key. Dont confuse, us collectively in the audience who is in this with us, dont confuse intent with ability. Or in other words, dont confuse devariesire with skill. Their intent and desire may be to kill all these people, but they dont have the skill and ability. They are not criminally sophisticated and not really practiced in bomb make iing. Look at the physical evidence. We talked about the shrapnel inside the bomb. If you were not wanting the bomb to go off, why not tape a bunch of nails to the outside. And why send two bombs to Maxine Waters and two to joe biden . One bomb will scare you. It doesnt scare you twice as much to get two. That shows me real ire, real hatred, real intent to get congresswoman waters. Clint can talk about that as well. Im going to get to the profile in a second. But jim, if. You had a chance to look at these devices, could you probably put them in the order they were made . Oh, yeah. They are going to be able to get that pretty quick. Maybe you could tell the bomber gets better at it type of thing. Youre going to be able to put the roll of tape together. The lab puts the whole roll of tape together. They are making all these together. Dont assume its one person. I think in this particular case, especially when i looked at that memes on the bomb, i have done that to clint before. I think thats an important factor. Ill let clint elaborate. All these things go into the investigators, the commanders trying to get ahead of the bomber. Chime in here. Im particularly the isis meme, how much would you be zeroing in on that as a profiler . Number one, i can tell you jim cav nag and i would rather be work the case than talking about it. But once you take senior status, thats what you do. Four quick things here. Let me take the other investigative track. Lets talk about the potential that suggested this is either a bad bomb maker or its intentional hoax devices. Number one in at least one or more of the devices, were not teaching a bomb making school. But i know theres one key component missing. That intentional, if its intention intentional, if its not, were going to see a new and improved version. Number two, we have this isis sticker thats stuck inside. Its like a high five type of thing the guy is doing. Its like his own inside joke or something. I think it was the cnn bomb. What are the two things that scare us . Bombs and anthrax. Why not do both at one time. If i can scare them once, ill scare them twice. Because if i have ten packages and they all have a florida return address, i dont want to go to delaware and drop them in the mail and have somebody look up and say how come you drove all the way from florida to mail these things. So thats potentially our epicenter. Its like you threw a rock in the pond and the ripples start to go out. Right now, florida may be the epicenter and the investigative waves are moving out from that point. Lets talk about how youd be profiling. And im curious the decision, this idea that he sent two. Jim referenced this may 2 to 1 person. This would indicate more rage. Any other things that could indicate . I think it could indicate more rage. But if its a hoax device, is it a double hoax . Is this someone that was irritated . And realize this guy or guys right now, they have had a bomb making factory. They have had an Assembly Line on their Kitchen Table or in their garage or basement where they built all these things. If they built them all and made this one mistaken flaw, im afraid were going to see more. But if what they intended to do was just put a shot across our attention and they want to follow it up with a message, i think jim said yesterday or the day before you could follow up with a letter right now saying, hey, i sent those. I can make 100 more. Listen to what i have to say. Were waiting for that message right now. What are the chances this is more than one person in your mind . This could easily be accomplished by one person. Now again. If we looked at the unibomber was one guy, the Oklahoma City bomber we had two guys doing it. One person could accomplish this. And the idea is how do you keep the secret . You do it yourself and tell no one. Thank you both. Much appreciated. Im guessing you feel the saim way. You wish you were working the case. Those guys will do it. They are good. Is thank you, guys. Ahead the politics of it l all. President trump knows who he thinks is to blame for the countrys toxic political environment. Stick around.

Those engaged in the political arena must stop treating political opponents as being morally defective. Welcome back. That was President Trump last night after the discovery of a number of bombs targeting high profile trump critics. Before he blamed the media for the anger in this country, lets dig into the political fallout. You heard that version of President Trump last night. But i want to play another bite from that same rally that did a nod to the current political environment. Take a listen. These radical is tammie baldwin. Im trying to say that nicely. Normally i would scream. Im trying to be nice. Is that the best youre going to get . It looks like it. You know what im struck by with trump. Obama started it. I wrote speeches for ronald reagan. He did not use the words republican and democrat. He would prefrefer to those guy the other guys, the other men. So did bill clinton. It was a trope of president s. Since they were the president of all the people and not simply the president of their party, they did not refer to party. So actually barack obama started by name. Trump has taken this to another level in his attacks on democrats. It reminds you of how far we have traveled for the president to be this direct in political partisan combat tans. Simply going at somebody for being a democrat when hes the one person in the country who has been elected by everybody. You could say that mocked him. We also say he says the quiet part out loud. Thats him saying the quiet part out loud. Im playing it as a guy that im behaving. If youre like Sarah Sanders, you do that moment. Hes the victim in all of this. Hes the bride at every wedding and the baby being christened. He was teddy. The other problem we have here is we have seen Political Violence throughout history. We have never seen it actually incited by the president. All of this is is a moral equivalence where Maxine Waters does this stuff. Its not the same thing. When you have a president who has this kind of a platform and uses it as amply as he does to praise a congressman who beat up a journalist. To talk about supporters about hitting protesters. He has to play a role. Its actually in the job description. Hes not doing his job. Its interesting. John kasich, who might run against him in the primaries, said that today. Hes not doing his most important job, which is protecting the country and that involves uniting the country when its having a problem. I think its helpful to johns point to sort of go back to what would be normal with any president. If this happened on their watch, what would they have done. First, they would have called the people who were targeted. Do we have any evidence. I keep coming up with the minimum bars. Making the call to the former president , nope. Canceling the rally last night, minimum bar, or not mocking his own. Small things. They complain about media coverage. I think in this case media is dieing to say thank you. Act like a president. But i think what we all need to think about is how do we handle this moving forward. By. Us, i mean everybody. I think we want to draw a bright line between harsh political rhetoric and incitement and teach the American People what the word collusion means. What is incitement to violence. Every time he starts to cross that line, everybody has to come down on him. Thats a slippery slope because of the word radical. We could sit here and make a case. Is it an incitement term meant to demean. Its a tough call. That was a price line. There are certain things he does in recent days by encouraging people to body slam reporters. That wasnt even the story of the day. It was a huge story when he crosses that incitement line. When they start saying lock her up, no, come on. Move on. Particularly now that we know he seems to be using his cell phone that is far riskier Hillary Clinton did with her et emails. Its not a big call. Im struck by once again what a cat skills comedian, that schich with am i being nice. They told me i had to be nice. Hes a c
