>> there's probably no better place to enjoy and see american culture from a german perspective. what do you think? >> same. i like it. i want to see people eating hot dogs. >> that's what we are here for. >> are you bummed joey chestnut is not here? >> it's a pleasure to see anyone. it's amazing. i wouldn't be able to do it. i would have two, that's about it. >> reporter: two is my maximum. i don't know how anyone can consume 51. i will leave it to the pros. i had a hot dog this morning and that was too much. very excited to be here. a lot of folks eager to ring in the independence day celebrations. happy independence day. >> two hot dogs, it's low. i will take it. thank you so much for that report. i'm yamiche alcindor. enjoy your july 4th.

good afternoon. happy independence day to you. today marks exactly one week since the first 2024 presidential debate. oh, how things have changed. the new comments from joe biden in the last few hours about what he calls a, quote, bad night and what comes next. millions of americans celebrating today are under scorching heat alerts, including in california as a heatwave there forces thousands to evacuate from wildfires. we will go live from one city threatened by the flames. this hour, an island with historic secrets in san francisco bay. we will reveal those secrets what it tells us about how america has thought about immigrants. we begin with president joe biden and not backing down, insisting he is remaining in the race for president, despite his rough debate performance. we are learning that president

biden was checked briefly by a doctor a few days after the debate as he defends himself in a new radio interview. take a listen. >> nbc is reporting that in private conversations with aides and family members, the president is torn between defiance and acceptance as two house democrats now call for him to drop out. in some discussions, he has acknowledged the debate aftermath may grow too large to overcome. in others, he is completely dismissive of the idea of dropping out according to four people familiar with the matter. the president will campaign in battleground wisconsin tomorrow. abc news will air biden's first televised primetime sit-down interview in total tomorrow night. this with a new washington

-- "wall street journal" poll show showing biden behind trump. >> he just quit. he is quitting. i got him out. that means we have kamala. i think she's going fwoe better. she's so bad. she's so pathetic. she's a [ bleep ]. >> joining us now gabe gutierrez, akayla gardner, donna edwards, and jennifer horn. good day to all four of you. gabe, starting with you, the white house now clarifying details about president biden's medical care. what do we know? >> reporter: yes. there were confusing statements

earlier from white house about whether president biden had undergone a medical exam this week. the president had not undergone a medical exam since february. last night, during a meeting with democratic governors, according to two governors president biden said he was checked out by a doctor. the white house confirmed the president has been seen by a doctor for regular check-ins since the debate. the president does travel with his personal physician. it's not uncommon for that physician to be on hand in case there's a need. that's typical of any administration. the white house confirming this morning that he has been checked by a doctor since the debate and that he is recovering well. you mentioned the interviews. he did two interviews taped yesterday. they are airing this morning. president biden is now making the case that he can do the job.

>> reporter: in that interview, the president trying to pivot from the message of having to defend his age and mental acuity, trying to pivot to the message, that election message taking on former president trump. >> as we were mentioning, the pressure cooker continues. what are the plans in the coming days to push off some of the criticism and right the boat, if you will? >> reporter: well, the campaign really believes that president biden is the best messenger for that, the best person to defend himself. that's why they are trying to get him in front of as many eyeballs as possible. his critics wonders why he hadn't done that sooner. some democrats on the hill wanted him out there sooner. as you said, tomorrow he heads to wisconsin. he is sitting down with that interview with abc news that

will air tomorrow night in primetime. then over the weekend on sunday, he heads to pennsylvania. then next week, the nato summit here in d.c., the white house says he will participate in a press conference. a lot of people will be watching him over the next coming days as pressure mounts on him to step aside. >> you will be watching along with akayla. how has the crisis management gone as we were mentioned a week post the debate? who is in this crisis management team? are they doing a good job? how do they feel? what are you hearing? >> the campaign has tried to get out ahead of polling that we are seeing that does show that biden looks to be under pressure and is performing worse than he was before. that's something that they tried to downplay and say the race hadn't really shaken up. that's proving to not be the case. that's exactly what is concerning lawmakers. i'm hearing the consensus is, they want to beat donald trump. they are questioning whether biden is the person to do that. we are seeing multiple house

democrats and former officials calling for biden to step aside or to float whether there could be other options. the key remark was from jim clyburn who said he would be open to a mini-primary. i thought that was a very interesting comment, particularly because he is an ally of biden and someone very close to him. >> donna, where are we in this? we have had polls that came out earlier this week showing a larger gap. we are talking about low single digits in terms of a pre and post-debate difference here. where are they? what's your perspective? >> i think certainly the president has a lot of ground to make up. he did that in some part with the governors that he met with just yesterday.

i thought that was a really important meeting, those governors came out expressing full support for the president after having spent a good deal of time with him. i think there's more support on capitol hill than is being reported. i'm talking to lawmakers who really are squarely behind joe biden. i think the president has the ability, especially over these next five days before congress comes back into session and lawmakers are in town to make up a lot of ground doing public events, staying in front of the public. the best way that he can refute the concerns that people have expressed is to be out there and to be engaging and to be unscripted. i think these next several days and certainly next week with the nato summit provide a real opportunity for the president to tamp this conversation down. >> we have seen -- we played a little bit earlier, jennifer,

the republican nominee really beating his chest based on the polls and post-debate evaluation of their performances. what is the best way for the republican nominee to take advantage of today's situation based on the president being on his heels, joe biden, the candidate joe biden being on his heels right now? >> i don't want to give advice to the republican nominee on how to do better on anything. trump's response has been very much what you expect. it has been dishonest. it has been -- he is telling lies. it has been distasteful in a way that he has expressed himself. i think if we're going to have an honest conversation about what happened at the debate and how president biden goes forward from here, then we have to have an honest conversation about donald trump as well. i think it's a big mistake to treat trump like he is just any other candidate running against a sitting president.

he is a convicted felon. he has been very clear -- people should re-read the "time" article, the imperial president, in his own words, about how dangerous another trump presidency will be. when the democrats and other voters are looking at what joe biden should do moving forward, they should be thinking very seriously about what it's going to look like if donald trump wins this race and who is going to be best positioned. it's naive to believe that you can just switch candidates midstream and everything will be right again. i'm strongly a believer that it is -- they need to give joe biden this next week to show what he can do, to show where he is, to show that he can correct, and then start looking at polls. then start making your public comments. >> gabe, back to you.

these polls that we are talking about, has the white house responded to the negative turn that has happened in two or three of the polls for the president as a candidate? >> reporter: look, the white house directly is very careful to comment on polling, because that has to do with the election. they bring up hatch act violations. the campaign has really tried to get out in front of these polls. yes, "the new york times" poll that came out yesterday as well as "the wall street journal" poll that you referenced. what the campaign has been trying to do is to try and blunt that criticism by saying, internal polling shows a tight race. there hasn't been that much movement post-debate according to that internal polling. they are trying to not just send that message to voters, to congressional democrats, but also to their own staff. they really tried to hit that message hard. a campaign call yesterday biden and harris had.

nothing to see here yet. it's soon after his debate. we really don't know. all this criticism is baked in. voters knew that joe biden was 81 years owed. they argue that the debate really hasn't changed the minds of many voters. they are downplaying the polls. we will have to see in the coming weeks how much the polls shift after these public appearances over the next few days. >> akayla, to you, you heard one week from jennifer. is your sense from the white house, from the campaign that they also feel that it's one week? >> i think they know the next couple days are crucial. i think the fallout in general from this debate has really highlighted that the enthusiasm for biden was not there. we talk a lot about doubles here. the enthusiasm for bide season deeper and more acute. he really still has problems with a lot of constituency groups, black voters, young voters, people concerned about the war in gaza. they are going to have to make up for that.

this debate revealed they have people who are not confident in the president and who are always concerned about the president's age. he will not get younger. he will be 86 at a second term. voters are thinking about that more as they head to the ballot box in november. >> gabe, akayla, donna, jennifer, thank you. hurricane beryl showing no signs of stopping as it churns through the caribbean. it could have its sights set on texas. more than 100 million people at risk of dangerous heat and severe storms today. we will talk to our meteorologist about what you need to know. new reporting about what the department of justice might have up its sleeve if the election interference case against donald trump gets delayed past the election. we are back in 90 seconds.

turning to the extreme weather we are seeing unfold this holiday weekend in the united states. heat alerts are in place for more than 100 million americans. several wildfires are already breaking out in the west. heading toward north america, hurricane beryl steaming towards the cayman islands. it bound it pounded jamaica. at least nine people have been killed. sam brock has more from jamaica. >> reporter: good afternoon. i'm reporting right now from

halfway between kingston and treasure beach where we hear some of the worst damage from beryl was inflicted. you have all of the trees in the roadway. this is all we have been seeing for 30 or 40 minutes driving west. it's jackknifing cars trying to get around traffic. we have seen power lines that are down. many vehicles really coming very, very close to these power lines. you can understand why the prime minister is urging people, please don't go near them. keep your distance. we do have updated information to get to as well from authorities. jamaica's police force has confirmed there have been two deaths related to this storm. one of them, a 26-year-old man playing soccer with friends as the storm was coming through. unfortunately, a ball left their stadium. he went to retrieve it in the water. he was swept out by the floods and has died. their thoughts with his family. there was a 26-year-old girl in the northwestern part of the island where she had a tree fall on her while she was in the

middle of her yard. she passed away. those are the only two confirmed fatalities right now. that's the number expected to potentially rise as you see all the folks trying to get back and forth to wherever their homes might be. communications are compromised. we will get more information we expect about injuries and potentially more fatalities. lastly, there were about 1,000 people that ended up in shelters last night. those are now hopefully retreating back to their homes. very much a situation in flux here as we head out to treasure island which has sustained the worst damage. more reports for you later. sam brock, nbc news. >> thanks. joining us from california, steve patterson. also with us, michelle grossman. steve, let's start with you. a lot of 4th of july celebrations across california. they have been nixed due to the weather. what's the latest on the wildfires? there are dozens throughout the state.

>> reporter: there are. the one here we should say nixed as well. i'm convinced it should have been nixed regardless of the fire just because of how hot it is. of course, the flames still encroaching here. 12,000 structures and homes and neighborhoods. this is one edge of a double-edged sword. the other is a good one. the winds have finally died down in this area. it has given firefighters just enough of a foothold to put some containment on this fire. yesterday was a very good firefighting day. the winds have stagnated, which means they got 7% containment on a 3,500 acre fire, which is quite significant considering what they were dealing with before. 30 mile an hour winds, red flag warnings. that's all died down. the damage has been done. four structures, including the home behind me, destroyed. four people injured. 26,000 people evacuated from their homes. it is ridiculously hot.

it's 9:00 this morning, probably nearing 90, 95 degrees as it is. yesterday it was 108 degrees all day long. today, fire officials are telling us it's going to be hotter than that for longer. imagine trying to battle flames with pounds of gear on in this sort of heat. not only that, but it stagnates the area, including this bone-dry vegetation you have sapping all of the moisture out of the vegetation, making it so much harder to put out the flames. as you mentioned, this just one of several fires burning across the state. burning across the west. nine new ones sprung up on tuesday, including this one. firefighters estimated to be battling 17 to 20 large, active wildfires across the west. thankfully, the one here seems to be more under control. but it's still dangerous with the situation including the incredible temperatures we are experiencing. they are not going anywhere.

>> steve patterson live in oroville. michelle, i was looking at the fire map. it was little bits of wildfires up and down the state just like the weather is in the 100s there. >> that's right. the dangerous heat is adding fuel to the fires. we will see this danger continue through days and days. we are not getting relief at night. that's tough on the body. that's when we rest and recover. we are looking at nighttime lows above normal. we have 130 million americans under heat alerts. two different heat stories. the prolonged heat in the west. we see days and days of above average temperatures. down to the south, it's the heat and humidity that is dangerous. daytime highs higher than normal, also adding in the humidity. it feels a lot hotter. that's dangerous. we have the jet stream to the north onoth sides here. it dips here, that's where it's cooler where you see the blue. look at some of the numbers. 112 in las vegas.

that's seven degrees above what is normal. portland, 91. then we head to the south. we are talking in the 100s. factor in the humidity, it feels like 108 in dallas. that's very tough on the body. when you see these, that's what you want to dress for, prepare for. that's what our body is reacting to. san antonio, feeling like 106. feels like 109 in baton rouge. by tomorrow, in the middle of the country, we see the dip. to the west, to the south, we look at the heat continuing. phoenix, 116, 110 in fresno. keep it hot. this is just so long. that's really tough on the body. san antonio, 100. that's seven degrees above normal. up to new england. we are talking about near 90 in manchester in new england. hot as we go throughout saturday, sunday, monday. this is a big weekend to be outside. you want to take precautions.

stay indoors. hydrate in the south with the humidity. d.c., warm throughout the weekend, into early next week. 93 on saturday. 91 on sunday. we are warm in birmingham, in the 90s there. that's the heat. look at the rest of the country, severe threat throughout the midwest. the warmth, very hot and humid in the south. the chance for some later storms in the mid-atlantic, northeast. keep that in mind. let's turn to hurricane beryl. we are looking at the location. 95 miles west southwest of grand cayman. moving away. winds are at 115 miles per hour. that makes it a major hurricane, category 3. it's moving quickly. that's good news. we want this out of here. it will move across the caribbean. there's the category 3. it's going to encounter wind sheer, that's a battle. we will see it weaken to a category 2 but still strong. as we go throughout time, by

friday, 6:00, 6:00 a.m., we have alerts there. really mountainous, tough terrain. it will tear apart the storm. we see a tropical storm by saturday. sunday is a tropical storm. this is what we are watching closely. we are looking at a category 1 storm. maybe most likely restrengthening to a category 1. it makes landfall along mexico, maybe southern texas. this is something we will be watching. >> hoping for the best on that. michelle grossman, thank you. new fallout from the supreme court's landmark presidential immunity decision. what could happen to the cases against trump if he wins the election? today marks two years since a mass shooting in highland park, illinois, which took the lives of seven people. we are live with how they are remembering the victims. er is i. but st. jude has gotten us through it. st. jude is hope for every child diagnosed with cancer

there's growing uncertainty today for the future of special counsel jack smith's election interference case against donald trump after the supreme court's immunity ruling last week. "the washington post" reporting, the justice department is prepared to pursue its cases against trump past election day up until the inauguration, even if trump wins. joining us now is vaughn hillyard and joyce vance, former u.s. attorney, professor for the university of alabama school of law and an msnbc legal analyst. good morning -- or good

afternoon to both of you. joyce, i want to start with you. i was reading through your article. you neatly, as best you could, broke this down in terms of what the supreme court's decision meant in three different major ways. you can summarize for us how to look at that. >> this is a heavy lift. the opinion is lengthy and legally dense. i'm going to try to do the one sentence version. forgive me if it takes two. the supreme court says, trump gets immunity for unofficial conduct. he doesn't get immunity for official conduct. then the supreme court does everything it can to define the sphere of official conduct very broadly, far beyond what many of us would expect to be official conduct from a president. for instance, things like tweeting to get people to his speech at the ellipse might qualify as presidential conduct, not the conduct of candidate

trump, which would be unofficial. >> vaughn, as we have been looking at this analysis, how has the trump campaign reacted to it about the immunity ruling so far? >> reporter: i mean, donald trump in his social media account has made it clear. the way he described it was exoneration. of course, we have heard that from donald trump before. that's the way he described the two impeachments and the lack of convictions with them. the reality is that this is in no part exoneration. but i think it matches the temperature in which he and his campaign feel like the impact of the supreme court's decision will have on the legal trials that await him as well as the one in new york that he was about to have a sentencing for this upcoming thursday. because of the supreme court decision, judge merchant granted a request from donald trump's defense attorneys to push back the sentencing, but also hear a

motion and take in briefings that would potentially toss the verdict all together in the hush money scheme and the 34 counts against him, not because of the underlying charges that were presented and to joyce's point the extent to which these were clearly, most likely private acts that he took part in in that payment through michael cone, but it was more so the evidence that was brought in before the jury over the course of the seven weeks. some of the evidence potentially being considered official acts, whether it be speeches or tweets that were used as evidence. for he and his team, they, of course, see potential of having that case tossed. also, the likelihood that these other three pending criminal trials are not going to take place until well into 2025. >> joyce, which case of the four might you suggest is the first one we should take note of that is challenged by this structure you were explaining of

official/unofficial? >> right. i think obviously the biggest impact is on the election interference case in d.c. itself. that will require considerable work by prosecutors to sort out the evidence. one of the problems, richard, with this supreme court opinion is that it leaves so much vague and unseen. the court, of course, suggests it will see these issues again when they come back on appeal after judge chutkan makes a decision about what evidence and what acts can stay in the indictment and what has to come out. that won't happen until after the election is decided. the supreme court has given trump an expansive and broad reading of his immunity, at least for now. how that holds up after the election and given its outcome remains to be seen. >> joyce, who determines the official/unofficial? is that the judge? >> in the first instance, it goes to the trial judge. it's a legal argument. she will likely hear evidence,

hold an evidentiary hearing to make this decision. this is how appeals work in any event. the supreme court goes overboard to make the point that it will come back to them. that they will get to review those decisions. ultimately, they make the call about what conduct former president trump gets immunity for. >> vaughn, how has this given a boost to trump supporters, trump donors? >> reporter: it's going to clear the pathway for the next four months to a little bit less of a headache for trump and his team. of course, that sentencing was supposed to take place on july 11th. now it's pushed back until september 18th, if that sentencing does, in fact, happen at all. there's the potential of having an evidentiary hearing before judge chutkan to determine the extent to which some of the charges from the indictments still apply or what evidence is

admissible. you could potentially see some of the evidence brought forward in a public setting inside of the courtroom or some even potential witnesses coming forward as soon as september or october. there is the potential that that doesn't happen before november 5th either. for donald trump and his team, they feel like they have been able to sidestep any potential major blows. of course, the guilty verdict was not -- did not do their campaign any favors. at the same time, donald trump, while sidestepping some of the facts around the case, is going to be able to over the next four months, as we will likely seen the campaign stage next week when he goes to florida and into pennsylvania, try to use the supreme court case to make the case to the public at large that these charges should have never been brought against him in the first place, which is, of course, only partway true if you look at the supreme court decision. >> joyce, quickly, what does this mean for the new york conviction that vaughn was alluding to? >> right. in new york, the issue is

whether or not evidence was introduced that is public official acts evidence. this isn't about dismissing counts. it's about whether improper evidence was used. one thing the judge will do when he decides this issue is look at the totality of the evidence and decide if the jury could have reached its verdict without considering any evidence that they decide involves official acts. the judge will do that not by the way because he thinks any of that evidence was official acts. he will give the trump people their best reading. he is likely to conclude that even if some of these calls, like trump's conversations with hope hicks are official acts, the jury would have convicted even without that evidence. lawyers call that harmless error. that would mean he could proceed to sentencing. >> joyce vance, vaughn hillyard, thank you both. up next, two years ago, a massacre at a 4th of july parade stunning the nation. we are live with how the city of highland park is honoring the victims. a little known secret about

it's an emotional day in

suburban chicago, where a city whose july 4th parade was marred tragedy two years ago is bringing the event back. in a couple of hours, a crowd of at least 1,000 is expected to gather for highland park's parade along a new route. earlier today, the city held a ceremony remembering the victims of the 2022 mass shooting when investigators say a lone gunman killed seven people and wounded nearly 50. maggie vespa was in highland park covering the shooting two years ago and is back is there for us today. tell us how people there are feeling now two years on and about the security at this year's event. >> reporter: security is obviously a top concern. as far as how people are feeling, you can see some people put our their chairs to reserve their spot like one does for a parade. we have police out walking around. swing over here to the left. showing, we are told highland park police are leading the security, working with federal

authorities and the doj. back over this way, the sign behind me, highland park strong. we see that slogan all over town. we are told the theme for this year's parade is, sweet home highland park. everybody is on edge. some people telling us they will not come out to a parade. one mom of a child wounded, paralyzed in the shooting, saying she doesn't think she can ever go to a parade again. there was a remembrance ceremony earlier for the victims. the mayor spoke just before that and talked about why she even wanted to move forward with this just two years later. take a listen to this. >> i also feel like we have an obligation to this community's children in particular. in the aftermath of july 4th, 2022, one of the third graders who came through city hall asked me, do we ever get to celebrate the 4th of july again? i said, absolutely. so today is that first step. >> reporter: this community

wanting to celebrate the 4th now without fear. we said, city officials expecting a crowd of 1,000. just to get into the ceremony, you had to register online. had you to go through metal detectors. there canines there. bags were checked. that's an indoor ceremony. at the parade, full security is in place. being led by highland park pd. they coordinated with the department of justice just to plan today's event. mixed emotions. some nerves on the ground as expected. they want to move forward. >> i remember i was on air when this particular story broke on july 4th. we were all asking, where is highland park? why this little town? we didn't know much aboutspect. the suspect did reject a plea deal. tell us more about the suspect and what's next for that case for the suspect here. >> reporter: yeah. somebody who grew up in highland park. this is a suburb north of

chicago. he was 21 at the time. lone gunman according to investigators. this happened just last week what you are talking about. a stunning reversal on his part. there was a hearing last week where he was expected to formally accept a plea deal, pleading guilty to the murders of the seven victims in exchange for dropping roughly half, the 117 charges against him. everybody shows up for the hearing, including victims' families. he tells the judge when asked, almost a formality, that instead he is not going to accept. he rejected the plea deal and said he wanted to move forward with a trial. he would have faced life in prison either way. that's the max in this case. a lot of the rationale was to spare the families of the victims the pain of a trial. that move, which infuriated families. they felt like it was a control tactic. his attorney saying he is within his rights. that move set the stage for an

emotionally charged trial that right now is slated to begin february of next year. difficult times ahead for the families. today they just want to move forward and celebrate this holiday. >> maggie, i'm glad highland park is standing strong this july 4th. thank you so much for that story. appreciate it. up next, a special report. how a race-based law passed in the late 1800s led to family secrets held for generations here in america. that includes secrets i discovered in my own family. >> a little surprise here, which are some of the records for your family, richard. these are for your grandfather. >> today is the first time i have seen this picture. have seen this picture y tech and to keep up. thank you, verizon business.
