will you take care of them for me? we'll do the blizzard thing, all right? >> alisyn is here with me. i guess to be fair, not a whole lot of dairy queens in new york probably. but if you've ever done a road trip, as i have, across the country, including through the midwest, you cannot not know what a blizzard is. am i right? >> what the hell is a blizzard? it's delicious. that's what a blizzard is. that's all you need to know. it's delicious. but there are a ton in new jersey. i'm surprised that he's not up on his blizzard knowledge. >> yeah. trump -- he literally knows the mcdonald's menu like the back of his hand. but i guess, you know, ice cream is not really his thing. he's more of like a burger and fries kind of guy. >> this is dairy queen. maybe he's just that committed to mcdonald's. >> yeah, i think so. i also think it's funny -- so two things. some reporters need to check back to see if blizzards were actually purchased for people in

the restaurant this time. second of all, this is not as gross as that time that he offered a piece of half-eaten pizza to someone at a pizza shop in florida. i think that he might get a pass for this one. >> no, i saw that. even his ardent supporters were like, no, thank you with the pizza. abby, have a great weekend. great to see you and good evening. thank you. good evening, everyone. i'm alisyn camerota. welcome to "cnn tonight." we have a fantastic show for you this evening. it's been quite a week of developments in the special counsel's investigations into donald trump. so what is jack smith's next move? well, tonight we're going to break down who he's talking to and what evidence he has so far. plus, a disturbing new study finds that nearly half the tap water in the united states is contaminated with so-called forever chemicals. these are dangerous synthetic compounds that are linked to cancer and other diseases. erin brockovich is here tonight

to sound the alarm. and the race for 2024, president biden getting support in his re-election bid today from a top progressive while former president trump and ron desantis are going after each other. and former trump national security adviser john bolton has a warning tonight. >> the indictments don't have any impact. he's been indicted twice. it hasn't had any impact. if he gets indicted two or three more times, who cares? i think the real question on what the election may turn on is whether the special counsel can get a trial date and hold it before the republican primary process begins. if he can't get it and this trial is delayed until after the election, i very much worry about what the outcome would be. >> okay. so let's begin with what we know tonight about jack smith's investigation. joining me now, we have cnn political correspondent sara murray, former fbi director andrew mccabe, and former watergate prosecutor nick

akerman. great to see you guys. okay, sara. you've been reporting on all of jack smith's moves. do you get a sense that the urgency or the timing has ramped up lately? >> look, it's always hard to predict exact timing when it comes to the special counsel. i do think what we have seen in this investigation are a lot of activities you would expect to take place near the end of it. we've been talking a lot about this december meeting with donald trump and a number of his advisers that really went off the rails. that's something that investigators had previously asked about, and now they're sort of circling back to. they're checking on it again with other witnesses. that's the kind of thing you would expect to see at the end of an investigation. we know they brought rudy giuliani in. they talked to him in a voluntary interview for two days. he's sort of a late in the game witness, another box for them to check late here. we know that they have negotiated some sort of limited immunity deals with folks. again, something you would expect to see later in the investigation. we also know, though, that there

are a few witnesses out there that they haven't talked to yet. are there boxes out there they want to check or essentially could they be reaching the end stages, the final stages of this investigation before they announce, you know, whatever indictments they may announce? >> nick, we learned this week that jack smith, special counsel, is focusing on this very heated oval office meeting that happened after donald trump had lost the white house. so when you look -- i don't know if you can see this tuly, nick. i hope you can. all of the different players. >> i can. >> oy. goo good. all the players at that meeting, erybody from rudy giuliani as well as white house counsel, who do you think prosecutors are most interested in? >> in terms of all those people? i mean in terms of the person who can put it all together, i believe is mark meadows. he was the chief of staff. he was really the in-between person between the willard hotel

people, steve bannon, rudy giuliani, roger stone, general flynn, and donald trump. as we know from cassidy hutchinson's testimony, he was going to go to a meeting on january 5th at the willard hotel. but due to her kind of warning, he did it over the phone. but he knew what was going on. he was carrying the messages between all the key players and donald trump. so if i had to pick one person on there that i think is the most important, he's the man. and from what we know, he's already testified in the grand jury. >> mm-hmm. >> now, i wouldn't believe that he'd be testifying in the grand jury unless he had worked out some kind of a deal, and he's basically coming clean on everything that he knows. >> andy, i want to ask you also about thisw york times" reporting tonight. and that iat trump's former chief staff, john kelly, said in a sworn statement that the

former presidented about having the i and other agencies investigate those two fbi officials who were involved in the russia investigation, peter strzok and lisa page, in other words, using the irs to basically punish them. and i was thinking this might ring a bell for you. your reaction? >> it does ring a bell unfortunately. so this is really interesting, alisyn, and it's consistent with statements that john kelly made to "the new york times" directly a few months ago about this same topic. the interesting development here, though, of course, is that he's made these same statements now under oath, under penalty of perjury, and apparently they're backed up by notes that he took in these meetings where trump made these requests about irs investigations of pete strzok and lisa page. so that's a substantiated, you know, essentially a piece of evidence, if you will, in that argument. of course it rings a bell for me

because i was the subject of a very rare and invasive irs audit as was jim comey. you know, the likelihood of us being subjected to the same sort of allegedly random audit is infinitesimally small although the postal service ig looked at this and didn't find any, i guess, particular suspicious things about it. i feel very differently about that conclusion, but i don't think it's surprising to anyone that donald trump was trying to use his access to the levers of power in washington to exact retribution against his perceived enemies. and whether that's through the department of justice, through baseless criminal investigations like the one that was focused on me for two years, or through the irs, this is what he does, and i think it's probably what the american people can expect if he's ever returned to the white house. >> nick, if prosecutors can prove that, that president trump

was trying to exact revenge on his perceived enemies, is that a crime? >> that's a crime. in fact, it's the exact same crime i investigated during the watergate scandal. richard nixon did the exact same thing. he had the head of the democratic party audited just because he wanted to create havoc for his enemies. he had an enemies list. he went to the head of the irs and asked that certain people be audited. so basically what donald trump is doing is taking the richard nixon playbook here and doing the exact same thing, probably without even realizing it. >> sara, tell us about rudy giuliani. so he may lose his law license? >> yeah. i mean we know obviously rudy giuliani has been facing some issues, and among them are questions about the future of his ability to practice law. and what we saw is an attorney disciplinary committee recommended that he should be disbarred here in washington,

d.c. it was a unanimous decision that they wrote. there are still steps that need to take place in order for this to happen. this isn't the final word. but he's also facing an ethics review in new york. again, this is because of these kind of claims that rudy giuliani was peddling in the wake of the 2020 election when he was one of trump's most vociferous supporters at the time and spreading these election lies. take a listen to just some of the things rudy giuliani said about the election. >> joe biden is in the lead because of the fraudulent ballots, the illegal ballots that were produced and that were allowed to be used. we use largely a venezuelan voting machine in essence to count our vote. we let this happen, we're going to become venezuela. we cannot let this happen to us. they look like they're passing out dope, not just ballots. it is quite clear they're stealing votes. this was the worst election in

american history. this election was stolen in seven states. let's have trial by combat! >> now, this disciplinary committee basically said, look, you are a sworn officer of the court. you can't be putting claims like this into litigation that are totally not based in fact, where you have no evidence to prove this kind of fraud. of course his allies are calling this a great injustice. but, again, the clips you're seeing there are from a time when rudy giuliani was much closer to the former president, and we're now sort of seeing the aftermath of that in giuliani's life. he's not one of these people that we've seen around donald trump who's getting his legal fees paid by one of the donald trump pacs. he's not as close to donald trump as he used to be. again, as i said earlier, he also recently spoke to federal investigators for two days. >> it's hard to imagine a legitimate lawyer wanting trial by combat. that's sort of the opposite of what the legal system does.

but, nick, would the special counsel ever want to cut a deal with rudy giuliani, or is he too flawed as a witness? >> oh, i think they would cut a deal with him in a nanosecond if he were to come totally clean, for sure. i mean he may have to plead guilty to something to do that. but, yes, i mean he was involved in every aspect of this. he can recount exactly how they created the big lie about this false election and fraud in the election. he was involved in talking to legislators trying to get states, the battleground states to change their votes. he was deeply involved with the phony electors. he was involved with john eastman, who came up with this crazy scheme to get mike pence to basically not qualify joe biden as the winner of the election. so, yeah, he was involved in every aspect of this, including, as i said before, being at the willard hotel where all of the

basic no good niks were kind of sitting around. all of those people there had either been pardoned by donald trump or had asked for pardons by donald trump. so, yes, he could be a key witness here. he also would have to deal, though, with what's going on in georgia because i think he's a target of that investigation as well. >> yeah. >> so if he's to cut a deal, he's got to do it in both places. >> it's complicated. andy, we're also learning the justice department has spent re than $9.2 million on jack smith's investigation of donald trump since jack smith was appointed in november, and that number, it's interesting wn you look at how it breaks down more than $2 million in salaes for all the people who are part of this investigation. $80,000 in relation costs to get people to, you know, where they need to be for interviews, et cetera. is that standard for investigations of this magnitude? >> well, nothing about these special counsel investigations are standard. but if you put it -- if you

compare the costs associated with robert mueller's special counsel investigation or john durham's special counsel investigation, it's -- i think it's appropriately in that same ballpark. i can't tell you exactly to the penny. >> well, john durham's was much less expensive. his was $1 million, i believe. >> you know, my recollectis a bit more than that. >> oh. >> if you lo at what jack smith has be tasked with doing and the amount that -- the amount of investigativtivity he has executed in the last few months on two entirely distinct and very complicated investigations involving numerous prosecutors and agents and hundreds probably of subpoenas, hundreds of interviews, an enormous amount of time in front of grand juries in d.c. and florida, you know, these are the sorts of bills that you can expect to see from this sort of activity. so i'm not shocked by it, and they certainly have a long way to go.

obviously you've got one indictment that will be going likely to trial at some point in the next few months to a year. and we can expect maybe another massive complicated indictment on the january 6th activity sometime in the next few months potentially. >> andy, i stand corrected. you were right. that john durham was $7 million, not $1 million. obviously i'm no mathematician. thank you very much for explaining how expensive and complicated these things are. great to see all of you. really appreciate it. so what does this mean for the republican primary? trump and desantis taking pot shots at each other today on the campaign trail. meanwhile, president biden picking up support from a top progressive. my panel has thoughts. oh, yes, they do, bakari. you're getting ready.

ron desantis accusing donald

trump of spending more time and money attacking him than supporting republicans. >> we have a lot more to do. i've also been attacked more than anybody as you know, will. you know, donald trump has spent over $20 million attacking me. that's more than he spent supporting republican candidates in last year's midterm elections. at the end of the day, people do want to win, though. you can't win with just republican voters. i think we showed in florida, you know, if you want a big victory, you got to win independent voters. you got to win people who haven't voted for our party in the last several cycles. i've shown i can do that, and i think we can do it nationally. >> okay. here to discuss the latest gop feuds and what's happening on the democratic side, we have jessica washington of the root, and our political commentators bakari sellers and scott jennings. scott, here's an interesting paradox about ron desantis. his poll numbers have been flat, basically haven't budged for several weeks. and yet his fund-raising, he raised $20 million in the three

weeks since he's announced. so is there enthusiasm for him or not? >> well, there is enthusiasm for him, and he is in a different class than the rest of the people running. the problem is trump's core hasn't moved. let's just rough it out. half the party wants to do trump, and half wants to do something else. the half that wants to do something else, he's got the biggest chunk, but he hasn't been able to dispatch the other people in the race. having a war chest which includes a bunch of money in a super pac and money they brought in from florida, that should help him move some of these people along in theory. but in my opinion, until he gets rid of some of them, it's just going to be hard to grow market share while you've got a bunch of people taking out 1% to 8% each. >> jessica, one of the things that ron desantis was saying is a problem for donald trump is you can't win with just republican voters, he was saying. but he's tacking to the right of donald trump. you know, as you know, his campaign, his pac put out that anti-lgbtq ad.

so who does he think that he will be appealing to if he's moving to the right of donald trump? >> it's really hard to get in his head because you're right. i mean he's saying, you know, i am more anti-lgbtq+ than donald trump, and then he's also saying, you can't just win with the base. it almost seems like a tactic for him because he has to say that. he doesn't have the base that trump has. so it's almost he has to say, well, trump has just slim margins and he's never going to be able to make it because he only has republicans. but if you look at desantis' base, it's inarguable that he doesn't have this moderate swell that he would need. >> well, in florida, he absolutely had moderates, and he had independents, and he had a bunch of democrats, and he did turn a lot of blue areas red. his argument is that he has turned a big purple state red, and i know you like to denigrate your own people that he ran against down there, but -- >> first of all, charlie crist is not my people. but go ahead. >> but it is inarguable that desantis had massive electoral

success among constituencies that republicans absolutely have to win and that trump has never gotten more votes than a democrat in his life. so his argument is intellectually correct. >> will that translate nationally? >> no. and the reason it won't is because ron desantis is the tim pawlentys of scott walkers. that is exactly what he is. i think in two, three, four months, we're going to not even be discussing ron desantis anymore. the problem is the more you get an opportunity to meet ron desantis, the less voters like him. in florida, he was able to run on policy recently. he was able to do an air drop campaign. it's a huge state. florida is like three states in one. he was a great statewide candidate. however, now you have to go and do kind of retail politics in iowa, retail politics in new hampshire, retail politics in south carolina. what they're realizing is ron desantis is about 5'8". they're realizing they don't really care for him that much,

his interpersonal skills and they're realizing he's not a true fighter against donald trump. in order for someone to win this primary, they have to be big on the future of this country, i.e. tim scott, and they have to be somewhat of a bully, i.e., chris christie. and there's no combination of both. >> that was profound. >> i took a moment to marinate there. >> is your best argument against a candidate for president his height? >> no. ron desantis is very, very short to be president of the united states. >> i mean is that an argument about it? >> literally. >> is joe biden -- why are we talking about -- >> how tall is he? >> i'm just asking. we've been on tv all day together and you keep referencing his height. are you worried about his height or joe biden's age? >> that's a tough one. but i will tell you this. i mean when the field shakes out, i believe firmly that we'll have two individuals that are close to 80 years old running for president of the united states. and i think that donald trump is

going to bully ron desantis out of the nomination. >> let's talk about what's happening on the democratic side. congresswoman alexandria ocasio-cortez was on pod save america, the podcast today, and she said biden has her 2024 support. so here it is. >> i think -- i think he's done quite well given the limitations that we have. i do think that there are ebbs and flows. >> will you be supporting joe biden for re-election? >> i believe given that field, yes. >> so what was interesting, jessica, is in february she wouldn't say that. she would not say yes. she said, i'm going to see how the primary process plays out. so what's changed? >> i think there's obviously no one stepping up to the plate to challenge joe biden. and i think aoc is more of a pragmatist than she's often given credit for. i think she has shown she wants to work with the party. she wants a democrat to be president. she realizes the existential threat of trump. so i think she's saying, okay, obviously biden is going to be

the nominee. there is no one else. so she's lining up behind him. i'm not that surprised by it. >> rfk jr. has raised a lot of money. you're laughing but he has raised $3 million within a three-day span at the end of the quarter. $6 million between april and june. is it time for democrats to take him seriously, bakari? >> absolutely not. you know how it's just -- robert f. kennedy jr. is the embodiment of everything that's wrong with social media. he is a caricature. he is -- you know, they say the apple doesn't fall far from the tree. i mean he's rolled off the orchard. he's not his uncle. he's not his father. i'm not sure why he's running for president other than just some reason to build up his own self. i don't think that joe biden should pay attention to him. i don't think he should debate him. i think that he's a caricature, and i think he will fade away.

>> quickly, scott. >> coddled by, created by, brought to you by the american left. rfk jr. is fully a product of the democratic party and the american left. >> that's not true. >> it's not? >> joe rogan and him are not the american left. >> it wasn't the republican party that brought this guy along for the last two, three decades. >> we don't want him. you can have him. >> on that note -- >> you can't give him away that easy. he's too tall for us, bakari. >> you can tell it's a friday night. thank you on that note. this next story is quite serious. it impacts millions of us. nearly half of the tap water in the u.s. is contaminated with, quote, forever chemicals. this is according to an alarming new study. and erin brockovich is here next.

we moved out of the city so our little sophie could appreciate nature. but then he got us t-mobile home internet. i was just trying to improve our signal, so some of the trees had to go. i might've taken it a step too far. (chainsaw revs) (tree crashes) (chainsaw continues) (daughter screams) let's pretend for a second that you didn't let down your entire family. what would that reality look like? well i guess i would've gotten us xfinity... and we'd have a better view. do you need mulch? what, we have a ton of mulch.

an alarming new study estimates that 47% of our tap water in the united states is contaminated with so-called forever chemicals. the u.s. geological survey tested 700 locations across the country and found out how

widespread these chemicals are. the epa believes these chemicals are more hazardous than previously thought. joining me now to discuss is consumer advocate erin brockovich, who has sounded the alarm on this for years. erin, thank you so much for being here. such an important story. what are forever chemicals? >> well, so they're chemicals that you would find, you know, pfoi, pfos, you would know as teflon. you would know it as a plastic coating, as firefighting foam, flame retardant that we use on our furniture and children's nightwear, uniforms, firemen and their gear. that is specifically what pfas and the chemicals are. >> what do they do to humans now we know? >> oh, my gosh. well, they create a lot of problems. they can cause pre-eclampsia in

pregnancy. they can cause testicular cancer. they can cause thyroid cancer. it can lead to liver problems. it can lead to higher cholesterol, higher blood pressure. itan lead to a plethora of diseases and cancers, and it's alarming because it took too long for us to study this chemical. it got into the marketplace decades ago. this isn't something that just showed up and happened yesterday. the companies have known. they have warned, and there's been a lot of agency failures and a quick response to corral this chemical before it became widespread throughout our water system across the country. >> here's the map of the hot spots where scientists found the highest concentration of these chemicals. so it looks like the northeast corridor from washington, philadelphia, new york, also cape cod as you can see there are particularly bad. but it is scattered throughout the country. do we know why it's concentrated

in those areas? >> well, a lot of where industry went and where they were using it. so we've been up in maine a lot. most people don't know this. almost the entire state of maine and its water has been contaminated with this chemical. it was found in the dairy milk. the usda delayed about 18 months reporting that to the state. the farmers have had to go in and kill all their cattle. you cannot use it in milk. it's gotten in the food chain there. it's gotten into the eggs. part of the thing with pfas and it's a family of chemicals of about 11,000 different chemicals, these are just four of them that we know of. but it follows proteins. so it gets into the food supply, which would be milk, cattle, beef, eggs, and leafy greens. so this chemical follows protein, and we uptake it. so we have a huge issue here with such a large groundwater

contamination because it's also entered our food chain. >> so, erin, what do we all do? how do we protect ourselves? >> well, you know, this is a good start. you know, a lot of people don't know about it because we don't talk about it, and it isn't until it's something national that it will really come to people's attention. but at a local level they're doing a lot of things in maine and in michigan. they're working with senators. they're getting statute of limitations extended because all of these farmers are looking for some type of recourse. the municipalities have been heavily impacted. the biden administration does have about a trillion dollar fund. it's called biden bucks is how we refer to it where these municipalities can go because they're going to have to put on very expensive filtration systems to keep this one chemical out of the water supply. people need to know about their

well water. they this have their well water tests. some states will come out and do well systems for them. so it's a matter of asking information or asking questions, getting a water report, working with your community, especially in the farming community, and start knowing if, in fact, you do have pfas in your water because you'll need the appropriate filtration to keep it out of your water. >> yeah. >> and this is a situation, alisyn, that's really just begun even though it's been in the system for decades because we haven't even begun to look at the sludge or wastewater. and we take a lot of that and apply it to farmlands, which is adding to the food contamination. >> well, it's really alarming, and you say that most filters only remove taste and smell. they don't remove these forever chemicals. but reverse osmosis, if you can afford it, it is the way to go. everybody needs to just be aware of it and begin thinking of how

they can keep themselves safe. erin, we could talk about it for hours. i'm sorry that we're out of time, but we'll have you back, and i really appreciate you sounding the alarm on this for us. >> thank you for having me. i hate to be a downer on this, but, listen, this is a big issue that's not only going to affect all of america but globally as well, and i can't think of anything more important than the protection and the safety of our drinking water. >> agreed. thank you for being here. really appreciate it. more climate and earth news. the earth has broken global temperature records virtually every day this week. our next guest has studied climate change for years and has two important suggestions for what we can do now. splash into savings

global temperature recor were shattered this week. one scientist tells cnn that this week's temperatures are probably the warmest in, quote, at least 100,000 years. monday's global temperature average beat the last high from 2016. then tuesdd top of that. anthursday's temperatures marked the hottest in recorded history. scientists say temperatures are in overdrive this month thanks to a combination of the natural climate phenomenon called el nino and human-caused global warming. joining me is monica medina. thanks so much for being here. it's hard not to feel powerless as wwatch the earth burn around us. on june 6th, new york city, as you know, was among the top places for the worst, most

dangerous air quality on earth because of wildfires in canada. so do we need to be prepared for more days like that ahead? >> we absolutely do. thank you so much for having me on tonight, alisyn, and thanks for these back-to-back segments on environmental issues. there's so important to our health and to our future. yes, we absolutely need to be prepared for more of the same. in fact, we've had five of the last eight years have been the hottest on record. so it's not just the last four days. it's years of increasing heat, and we know that heat is deadly. it is something that we need to take seriously just like those bad air day last week and the weeks before that in new york city and all over the east coast, and as far west as chicago and as far east from us as europe. so we know that this is what we're facing, and we have to

adapt. and we can adapt. >> let's talk about that because i do -- monica, sorry to interrupt, but i think sometimes people turn away from these segments and this topic because it feels so overwhelming, and we feel so powerless. so i was heartened to read that, you know, you have suggestions. we can still do things. it's not too late. so what do we do to adapt now? >> i think it is definitely not too late. we cannot give up. we don't have any choice but to adapt, and we've always understood that change happens, but so do progress happen. that's why we need to keep going with our energy transition. we need to wean ourselves off fossil fuels. but the other big thing that we can do, and this is what we are really working on at the wildlife conservation society, is to conserve nature all over the world. the most effective carbon sinks we have right now are trees. our nature and wild places, intact forests in places like

the amazon and the congo, places where we work today to conserve nature and biodiversity as those natural barriers and defenses to what we see as this incredible warming, whether it's trees in cities and planting trees in cities like we're doing here in the u.s. with some of the new climate legislation that was passed by congress, or whether it's preserving intact forests. there's a lot we can do with what we have today. and then if we lean into technology, things like clean energy, new ways of transporting ourselves. just this week, the international maritime organization has improved shipping -- has set goals to improve shipping emissions. so we know that we can do this. we just have to keep trying. >> and we only have about 30 seconds left, monica. what can individuals do today? >> what individuals can do today

is mobilize for political action, i think, to continue to lean in to these new efficient cars, new and more efficient energy technologies, supporting wind, solar, all of the transitions, and supporting conserving nature and biodiversity everywhere that we can around the world. >> yeah. great advice. monica medina, thank you very much. it's really nice not to feel hopeless about it as we watch everything that's certainly been happening this week. thanks for coming on. >> thank you. there's been a slew of shark bites off the coast of new york, and it has officials trying something new this weekend. so next i'll speak to an expert who gets up close and personal with sharks. this is him, about how we stop this. angry rhino. baby i hear one every night... every night. okay... i'll work on that. the queen sleep number 360 c2 smart bed is now only $899.

and wildlife biologist forest galante. thanks for being here. there's this website, trackingsharks.com. they say the numbe suspected shark bites this summer has already surpassed last year's total. why are sharks biting us more? >> well, specifically in the northeast, alisyn, what's going on is there have been increased bunker regulations, which is a small species of bait fish. as that fishery has rebounded from near collapse, what's that done is brought in a whole lot more predators. we're seeing more dolphins, more whales, and of course more sharks. with more sharks comes a higher likelihood of an encounter with a shark and occasionally those encounters happen to be negative. >> thank you. that is really helpful in explaining what is going on. do you think that the plan for using drones to spot sharks before they can bite swimmers will work? >> i absolutely do. i mean i think that it would take a lot of drone coverage at

all times, which is something that's very difficult to implement. that being said, you know, my team and i use drones all the time to monitor sharks up and down beaches and especially in shallow areas where you don't necessarily need to know what the species of shark is as long as you can make out the outline. you can use a drone to fly overhead and look for those sharks. but honestly the better methodology is to be a safe beachgoer and a safe swimmer and make smart choices when visiting the beach so that you avoid an encounter in the first place. >> like what? what am i supposed to do when i go to the beach? >> that's a good question. so there's a couple things you can consider. first of all is not swimming where people are cutting up fish or cleaning their catch if they've been fishing, not swimming near river mounts where water is typically dirtier and sharks are hunting. sharks hunt during dusk and dawn, so choosing to avoid swimming during those times is a good idea. then if you do encounter a shark, just stay calm because

that panic, that splashing, that's what leads to the case of mistaken identity in which sharks are biting people. these are not attacks. these are cases of mistaken identity. they see a hand flashing in the murk or a foot in the sand. they think a nice juicy fish, take a bite and go, yuck, that's not a fish, and let people go. >> let's watch what happens when you encounter a shark because you study sharks for a living. we have this clip of you free diving to get up close and personal with, i believe, a bull shark. so let's watch this and listen for a minute. >> this is our best shot. now, if i can just get her to come check me out. probably weighing close to 2,000 pounds, this hungry mama nearly knocks me over. >> that's awesome. should we all do that, just grab

the shark by the snout when it comes up to us? is that what we should do? >> definitely. do everything you see on tv. you know regardless of your experience level -- no, of course not. don't go swimming with giant tiger sharks or pushing any sharks on the nose like i did there. that takes years of training, years of understanding the animals. we were there collecting samples. that shark, as you saw, came to me, and i wasn't going to push her around. don't do that, you know. if you want to get bitten, that's a very good way to do it. so i don't recommend trying to fiddle with sharks. instead, i recommend very responsible and safe visiting of beaches and oceans and the likelihood of a shark encounter is very, very minimal. >> all right, forrest, thank you very much. thanks for the tips. i'll be avoiding the ocean at dusk and dawn. thanks for all of that and thanks for sharing the great video with us. have a great weekend. >> thank you. well, the july 3rd mass

shooting in philadelphia has drawn national attention, but for one anti-violence advocate, it hit very close to home. 2022 cnn hero tyrique glasgow has been working for a decade to make his south philly neighborhood safer, building bridges with the police and providing critical support to hundreds of residents. now the loss of more loved ones has made him even more determined to keep pushing for positive change. >> the reality of, you know, just hearing gunshots is normal in our community. the family members and friends that have lost are countless. i knew two of the victims. my cousin, he always looked out for me growing up. he wasn't a young man out here selling drugs, carrying guns. he was one of the young men who wanted to do right. and to have him taken away senselessly, i was hurt. we need to provide a table of resources instead of having this

table of grief. today we started our summer camp and working with the kids, having a safe place for our children. >> what's your favorite color? >> that's what we try to do every day. our community engagement center helps us really provide those essential quality of life resources. they're small acts that really change a community's trajectory. i believe that's how we grow as a community, lifting each other up. it allows me to keep going forward. >> you can find out more about his work and nominate your own cnn hero at cnnheroes.com. nominations close july 31st. thanks so much for watching "cnn tonight." our coverage continues now. meet the portable blender we can barely keep in stock. blendjet 2 gives you ice-crushing, big blender power on-the-go. so you can blend up a mouthwatering smoothie,
