Stuck in the mud. Some 70,000 people stranded at burning man. Heavy rain stranding them in nevadas desert while roads are expected to be reopened today. Were following the latest. Plus President Biden sticking with a familiar playbook, talking up the state of the u. S. Economy and shoring up union support. But is it working . New polling showing the economy could be the biggest threat to his reelection. And a leadership shakeup. Ukrainian president zelenskyy dismisses his Defense Minister and says its time for new approaches in the war with russia. What that could mean for the counteroffensive. Were following these major developing stories and many more all coming in right here to cnn news central. Soon a mass exodus out of the mud. Organizers of The Burning Man Festival in nevada say they hope that in just a couple of hours tens of thousands of people whove been stranded in the desert can begin to drive out. For days now festivalgoers have been trapped in treacherous ankledeep mud advised to shelter in place and to conserve food, water and fuel. The area was slammed with two to three months worth of rain in just the span of 24 hours. Officials say about 72,000 people are still stranded. Some of them choosing to risk it, hike for miles in the mud to leave. One of them being the popular musician diplo. He actually posted this video after he trekked through the mud, hitching on the back of a pickup truck alongside comedian chris rock. We should anticipate hearing some jokes about that pretty soon. Cnn National Correspondent nick watt is covering all of this for us. So nick, what are officials saying are the next steps in trying to get folks out of there . Reporter well, boris, the latest we have heard is they say in a couple of hours from now, thats noon local, 3 00 eastern, they will open the roads. Right now they say, quote, that road, its not really a road, its mud, is still too wet and muddy for most vehicles. But we have seen some people trying to get out this morning and succeeding in those vehicles. The issue is the more vehicles that are on that mud before its really dry could cause problems later in the day. The sun is the savior here. Listen, the rain, that makes that clay very quickly unpassable but the sun also dries it pretty fast too. I mentioned some people have already made it out. Cnn spoke to one of them. Take a listen. We planned on leaving right after the burn, which is saturday night. And then it started raining on us. Like that night. And we were like oh, its fine, its okay. Everybody was still partying, having fun. Everybody took their shoes off, started dancing in the mud. It was great. And then the reality sunk in that we couldnt leave. Like we were stuck, basically. Reporter yeah. And i mean, the only kind of fairly unpleasant exit was, as you mentioned, boris, to walk. Chris rock apparently wearing his New York Knicks jacket walked out with diplo. Cindy crawford and a few others, they walked for three hours in the mud. And then some kid passing in a pickup truck recognized diplo and gave them a ride, and they eventually made it to reno. But quite a lot of people decided to stay. You know, there is a real kind of ethos of selfreliance around this festival. And some people said listen, i could have walked out but then i leave my rv and all my stuff. What do i do . And nothing really bad happened. One person did die, but were told that was not connected to the weather. And they say people mucked in, people helped and tonight they will finally burn the man and pray for no more rain. Boris . Yeah, a lot of folks not wanting to leave until that effigy that the festival is named after was burned. Nick watt, thank you so much for that. Lets go to cnns chad myers, whos at the Weather Center for us. Chad, how did this get so bad so quickly . Training rain. One storm moved over the area and then another one right behind it moved right over the festival again. This is in a rain shadow. This is in a place that doesnt rain much ever. This white area right through there. Theres lake tahoe. Theres reno. Well zoom in for you. You can actually see if you want to go to google earth you can actually see the city itself, kind of a ring here. A little bit faint but you can really see whats going on right here in the burning man, there in the middle. And there are no roads. No paved roads here whatsoever. This is just that silt. The clay that got wet. Its like walking into a lake and expecting not to sink down a little bit when you walk in off the shore. All of that was just completely saturated. There was no place for that rain to go. And so the people just got stranded there. That clay gets very, very slippery. Heres the rainfall. Just one area after another. Thats the area right there. Watch that little white spot right there. Thats where the Training Rain just came over and over and over for hours and hours and hours. Theres just no way to predict this. This is kind of monsoonal moisture. It comes down in the Desert Southwest every single winter season, spring season. You get the moisture coming up. Especially in the summer. The humidity is involved. And it just pops a thunderstorm or it pops the rain. And even talk about phoenix. You can get two inches of Rain In Scottsdale and it doesnt rain at all in awatuki which is just a few miles away. Thats kind of what we had here. Just rained in the wrong places. No more rainfall. Thats the good news. This now just has to have the sun to dry it up. People ironing out some of these roads or at least trying to get through some of these roads here. Likely a maintainer, one of those big scrapers would have helped a little bit, try to get some of that mud away. But here you go. This is what it looks like. Thats what turns silt and clay into rain and mud. So how it happened is because this rain has no real place to go. Its not going to soak into the ground like if you had loam, which is peat moss, or the dirt, the regular dirt below it. This is a dry lakebed thats been dry for a very long time. Silt has blown in. Clay is everywhere there. And when it rains on top of the clay it just sits there and becomes a soup. It doesnt soak into the ground. Thats what theyre driving on right now. Theyre drive out on mud soup. Lets Hope Everybody gets out of there today. Probably theres an awful lot of trailers that are going to go very, very slowly to get out of there. Well see if we can get everybody out today. Boris. Yeah, a most unpleasant soup. Chad myers in the cnn Weather Center. Thank you so much. Omar . Yeah, im going to pass on that soup for lunch this time around. But look, this is a serious situation for a lot of people. I want to talk more with someone whos been experiencing all this at burning man. Angela peacock joins me now. Angela, good to see you. I know you were worried about signal. So im glad to see youre actually beamed in here. But for starters tell me what is the situation right now . It definitely looks dryer than what it was i can imagine over the past few days. Camp just had a meeting and they said theres a really, really long line trying to get out. Some people are leaving. I think mostly the fourwheel drives, the super vehicles, not the Passenger Cars yet. There are a if you have those stuck. So right now our camp is focusing on breaking everything down, packing up, just sort of waiting it out. And probably as you heard, the burning man will burn at like 9 00 p. M. So everybodys kind of just taking their time until then tonight. Yeah. And look, it seems that its become a situation over the past few days where you know, youve really had to work with some of the other people there, that some of the set rules that maybe were in place when you got there all of a sudden you had to improvise a little bit. Have you seen people help each other out, share food and water . What has the dynamic been like over the last few days . I mean, honestly, its brought us closer together. You know, theres principles to burning man. One of them is radical selfreliance, meaning you bring enough to take care of yourself and help others if needed. And you gift things. Like theres no payments. If you need food or you need water or you need something, theres someone here that will give it to you. Theres even a saying we say the playa provides. Like things will be provided. Youll be fine. Honestly, its brought us closer together as a community. Lots of teamwork. Lots of getting to know people on a deeper level because theres not much else to do. So its been fine. Totally fine. Yeah. And radical selfreliance. Im sure people didnt anticipate going as hard into that motto as they have over the past few days. But it does sound like the dynamic has been helping people out. We know and you mentioned a little bit that some people have been trying to get out, decided to walk out or potentially get rides out on some of those fourwheelers that you mentioned. I mean, how difficult is that right now . Well, i mean, most of us are smart and were not even going to try because if you even try to ride your bike or you walk theres lots of dry pockets but then theres puddles still and theres still a lot of very wet stuff. So as you ride why you are bike or as you walk or as you drive youre going to accumulate mud on those tires and those feet. It makes everything harder and you dont want to get stuck in this and then prevent other people from leaving. So everybodys being really cool about it. Were just biding our time. Were finding stuff to do. Its a pain for some people with flights and Travel Schedules and work schedules, but you know, were doing the best we can and everybodys in really good spirits. Yeah. Angela peacock, well, i hope you get out of there soon. But it sounds like you all are handling it as well as you can, especially for how quickly the conditions there changed. Angela peacock, thank you so much. Boris . So President Biden is spending part of his labor day in the Battleground State Of Pennsylvania. He celebrated Union Workers, defended his economic record, and slammed his predecessor. But even with near record low unemployment, a strong stock market and lower inflation the president is having a tough time selling bidenomics. A new Wall Street Journal poll out today shows that just 37 of respondents approve of bidens handling of the economy. Nearly 6 in 10, nearly 60 disapprove. Lets take you to philadelphia now with cnns arlette saenz. So arlette, President Biden has to be feeling some pressure to get that perception shifted, especially because hes facing a reelection. Reporter yeah, boris and President Biden came here to the Battleground State Of Pennsylvania to try to make his economic pitch to voters. The president spoke at a rally for Union Workers as they got ready to go on their Labor Day Parade here in philadelphia. And the president really tried to promote some of the progress that has been made based on the policies from his administration, pointing to job creation. Also a moderation in inflation, though he did note that there is still more work that needs to be done as americans are still suffering from high inflation. But he also used this speech as an opportunity to take a swipe at his predecessor, former president donald trump. He never named him by name, but he was trying to make an economic contrast with him. Take a listen. When the last guy was here, you were Shipping Jobs to china. Now were bringing jobs home from china. [ cheers and applause ] when the last guy was here, your pensions were at risk. We helped Save Millions of pensions with your help. [ cheers and applause ] when the last guy was here, he looked at the world from park avenue. I look at it from scranton, pennsylvania. I look at it from delaware. Reporter now, this all comes as while there are some bright spots in the economy the president still is struggling in some polls when it comes to americans perceptions of how theyre doing economically. As you mentioned, his Approval Rating when it comes to the issue specifically of handling the economy sits at around only 37 . Its a bit lower when you take a look at his handling of inflation. All of this the white house has really over the course of the past few months, really tried to chip away at, trying to show that the policies that he has enacted, things like the Inflation Reduction Accuracy things like the bipartisan infrastructure bill, that those are ultimately paying off for voters. Of course the question will be whether in November 2024 if americans are feeling that the economy is in a good state. Of course the president traveled here to pennsylvania, a Battleground State that he won, it helped him win against donald trump back in 2020, and its a state that he will need once again if hes going to gain reelection in the upcoming election. Boris. Arlette saenz from philadelphia. Thanks so much. Omar .

Morgan Stanley is partnering with the Womens Tennis Association to remove boundaries. because this game is for everyone. Right now donald trump is the clear favorite in the 2024 republican primary, but can he even be on the ballot . Its a big question to ask. Several conservative legal scholars say no, that the Insurrection Provision in the 14th Amendment bars trump from running. One gop candidate, asa hutchinson, tends to agree, and some Battleground States are even looking at the issue. And now a sitting senator has weighed in. The language is specific. If you give aid and comfort to those who engage in an insurrection against the constitution of the United States it doesnt say against the United States. It says against the constitution. In my view the attack on the capitol that day was designed for a particular purpose, at a particular moment, and that was to disrupt the peaceful transfer of power as is laid out in the constitution. So i think theres a powerful argument to be made. My sense is its probably going to get resolved in the courts. A lot to talk about here. Lets discuss with former federal prosecutor renato mariotti. Renato, good to see you, one. Happy labor day. But i want to start with is this 14th Amendment case against donald trump as cut and dried as senator kaine makes it seem . Well, its not because its never a provision that has ever been exercised in a context like this before. And so ultimately i do agree with him this much, that the courts are going to get involved, and without really any precedent in the courts can look at in the past. I think it gives a lot of freedom for the United Sta
