he's got the dave matthews band. he will be in california through election night. all right. >> dave matthews. all right. chris jansing, always great to see you. have a great weekend. thanks for watching this hour of msnbc live. i'll see you back here at 1:00 eastern. peter alexander picking up our coverage right now. right now on "msnbc live" dueling attack. donald trump taking aim at hillary clinton in california, responding to her blistering speech where she said he is unfit to lead. outside trump protesters became the targets, met with flying food and flying fists. tragedy in texas today. five soldiers confirmed dead at ft. hood after being swept away in flash floods. we're live on the scene as officials ramp up their search for four others still missing. and officials now confirming that prince died of an opioid

overdose. at this hour still lingering questions about how the pop star obtained the powerful drug that ultimately cost him his life. good morning to you, i'm peter alexander, in today for my friend, tamron hall. we're going to begin with the gloves coming off between donald trump and hillary clinton, trading some of their harshest attacks yet. of course it came as new violence erupts outside a trump rally in san jose, california. these are some of the latest pictures. it happened last night. anti-trump protesters clashing with trump supporters. one woman, a trump supporter you see here, was pelted with food and was hit in the face with an egg. protesters were also seen burning an american flag. this is from video posted by buzzfeed on twitter. the protesters also grabbed "make america great" hats, setting one on fire. one officer was assaulted and a few arrests were made.

meantime inside the venue, trump fired back at clinton hours after she delivered that blistering 35-minute speech arguing that electing trump would be a, quote, historic mistake. >> donald trump's ideas aren't just different, they are dangerously incoherent. they're not even really ideas. just a series of bizarre rants, personal fueds and outright lies. he is not just unprepared, he is temperamentally unfit. this is not someone who should ever have the nuclear codes because it's not hard to imagine donald trump leading us into a war just because somebody got under his very thin skin. >> you know, she's up there and supposed to be a foreign policy speech. it was a political speech. had nothing to do with foreign policy.

now she's saying donald trump, do you trust him with the nukes? let me tell you, my temperament is so much tougher and so much better than her temperament. and by the way, we need a tough temperament. >> nbc's hallie jackson is covering the trump campaign for us. she is joining us now from san jose, california. hallie, trump responded this morning to the violence outside his rally last night. there's really been bipartisan condemnation of the assaults that we saw taking place on camera. >> reporter: yeah, so let's talk about trump first, peter, and then we'll get into what we're hearing from some democrats. trump responding in the format that he likes on twitter, tweeting this morning the rally last night in san jose was great. tremendous love and enthusiasm in the hall. big crowd. outside, small group of thugs burned american flag. i think you showed some of that video from buzzfeed a couple of minutes ago. trump is right in that there was a lot of enthusiasm inside the

room when he was delivering that speech, forcefully condemning hillary clinton and condemning her foreign policy speech yesterday. even outside as you look at some of that video, we saw trump supporters being attacked by some of these protesters in a demonstration that lasted for hours. it lasted until 10:30, 11:00 here local time. what we're hearing, for example, from the san jose mayor this morning, a spokesperson saying the mayor, while he believes donald trump is helping to antagonize some of these protesters says there's simply no place for violence with people who are trying to exercise their political participation right. you also heard from, for example, jon podesta who also said there is no place for violence against supporters of either candidate. trump inside, while going after hillary clinton, really hit her hard on the e-mails. one thing we didn't hear him talk about is the speaker ryan endorsement. he did hit hillary clinton again and again saying very forcefully

that she needs to go to jail. expect to hear that much more from donald trump over the coming months as that general election fight heats up. >> and trump does have a rally several hours from now taking place in redding, california. that's further up in northern california, a small, more conservative part of the state. it's supposed to take place in an airport hangar. what more do we know about police preparations there given what we've seen across the state already? >> reporter: listen, we've reached out for the redding police department, peter, for more on that. presumably they are aware of the protests that have happened at donald trump rallies. as you very smartly point out, yeah, it's a more conservative part of the state. it's a small town. it's a hangar, which means donald trump will be flying in and flying out. it's not like downtown san jose or albuquerque or anaheim where you've got easy access on foot for people getting transportation, for people coming in. so the other part of it too, the timing, it's happening at 1:00 local, 4:00 eastern.

middle of the day. oftentimes again, we see these rallies escalate once night falls. so potentially it appears as though there's going to be less potential for clashes like what we've been seeing. >> collectively we hold our breaths again. hallie jackson, california, thank you very much. now to hillary clinton, who is holding her next campaign event just a couple of hours from now in culver city, california, next to l.a. she's holding several events in the state and her husband is also campaigning there. kristen welker is in los angeles today covering the clinton campaign. kristen, good to talk to you. give me a sense, what is the clinton campaign saying today after that speech? obviously internally there were a lot of good feelings that they finally, as you described it earlier, may have cracked the trump code. >> that's right. you and i have been talking about that, peter. good to see you as well. the clinton campaign feeling good today about what happened yesterday. i think you can expect to hear some of secretary clinton's greatest hits on the campaign trail today.

she has four stops. wants to win here in california. but she is going to again take aim at donald trump. yesterday she delivered that 35-minute blistering attack which you described and what was effective about it, particularly from the point of most democrats, this was the speech that they had been waiting to hear from her. she took on donald trump's foreign policy proposals point by point. the fact that he hasn't enumerated how he's going to take on isis, the fact that he said it would be okay to for south korea and japan to get nuclear weapons, his proposed muslim ban. if you talk to analysts, they said what was effective was she found a way to mock him, while at the same time taking the prospect of a trump presidency very seriously. so this is the blueprint for what we are going to see in the days and weeks ahead. now, you'll note that some of trump's gop rivals took a similar tactic during the primary, but the thinking is some of those attacks came too late. so is secretary clinton getting ahead of the curve here? we'll have to wait and see. that's the big question mark.

again, peter, one of her biggest challenges, she is still very much mired in this primary battle trying to clinch her own party's nomination and that's why she is so aggressively campaigning here in california as is senator bernie sanders. he hasn't left the state for days. he's going to be here through primary day. she could win the nomination without winning california, but if she wins this state, peter, the most populous state, it makes it a whole lot more difficult for him to stay in the race through the convention. >> definitely right, and campaigning with celebrity women today, senator? >> that's right. look, this is something that you'reoing to see from secretary clinton movin forward. she thinks that rallying her base, women in hollywood, women in all different sectors, is a way to rally this critical voting block that clearly prefers her by more than 20 points over donald trump. so this is a big part of her election strategy as well. >> kristen, thank you very much. now to that big trump

endorsement, it turns out just a single tweet ultimately ended what was an unprecedented standoff. after repeated refusals to endorse donald trump, house speaker paul ryan has finally had a change of heart. he says he is now confident that trump would help turn the republicans conservative agenda into laws. >> reporter: donald trump making no mention of the latest convert but earlier tweeting so great to have the endorsement and support of paul ryan. that endorsement less an embrace of trump than a rejection of his opponent. >> it's very clear to me that hillary clinton is in no way going to advance our principles and policies. >> reporter: the highest elected republican shifting from reluctance to acceptance, over 29 days after the outsider became the gop's presumptive nominee. >> donald trump is somebody i know that's comfortable with these principles and these general policies. >> reporter: but a "washington

post" editorial calling it a fantasy that mr. trump would advance a gop agenda, saying ryan capitulated to ugliness. the men have differences, competing views on immigration, trade and a muslim ban. just this march ryan called out trump for failing to condemn david duke. >> if a person wants to be the nominee of the republican party, there can be no evasion and no games. they must reject any group or cause that is built on bigotry. >> reporter: the endorsement concludes an unusual courtship. >> paul ryan, i don't know him well, but i'm sure i'm going to get along great with him if i don't, he's going to have to pay a big price, okay? >> reporter: the pair have spoken on the phone several times but ryan profiled for father's day refused to answer the magazine's questions about trump. >> one of the most important stats right now is that 86% of republicans now support donald trump. of course there are still

several significant holdouts. among them paul ryan's former running mate, mitt romney, both former presidents bush as well as new mexico governor susana martinez. on martinez, trump is now changing his tone and in fact his tune just days after publicly attacking her. trump told martinez' hometown newspaper in santa fe, quote, i respect her. i've always liked her. now let's go to capitol hill and nbc's luke russert. luke, let's get the reaction more broadly to paul ryan's endorsement and whether or not we're going to see paul ryan actively campaign with donald trump at any point or was in in effect just something he had to do? >> reporter: well, they're leaving the door open to that, peter, but i think if anyone has any expectations that paul ryan is going to get up on stage in wisconsin and raise the arm up like this with donald trump, that's not going to happen any time soon. it's unclear whether or not paul ryan will even get a formal speaking role at the republican

convention in july. of course he's the chairman of that convention by nature of being the speaker of the house. i'm told that ryan came to this decision, it was a difficult decision for him because he does have a lot of differences that he pointed out in that great piece with donald trump. but it's this idea of, look, he was on an island. every other congressional republican leader said, hey, we have to go in with donald trump, as has both the campaign arms of the senate and the house. but it was also this idea that after long conversations between trump's staff and ryan's staff, ryan's team felt that trump would enact parts of their house gop agenda that's coming out today called a better way. it's republican ideas on how to deal with poverty, national security, taxes and whatnot. >> luke, isn't that just striking that it's called a better way. so even a day after he said i'm all behind donald trump, he came out less than 24 hours later with what is in effect his response. >> reporter: and ryan has always said he's going to run a parallel campaign to the

presidential one. he wants to be the part of the republican party that talks about ideas. he's going to lay out his ideas on paper over the next six weeks while congress is still in session before the recess. it remains to be seen whether or not donald trump will run on that policy. ryan made the determination that in the first 100 days of a trump administration, there's a lot more he can get done with trump than he could get done with president clinton. he called hillary clinton in that op-ed in the newspaper a liberal cronyism, four more years of that, so he's positioning himself there. but let's not -- let's not just throw this to the wayside. there are real differences. the muslim ban deeply upset paul ryan. not being quick to disavow the association with the kkk deeply upset paul ryan. i can tell you personally from conversations i've had with paul ryan's team, some of the things trump has said about women has not settled real well. so they are not friends and i think it remains to be seen just

how far ryan will go. but look, donald trump i'm told by a lot of people here on capitol hill, there is not a lot of domestic policy there. if he is president, he will supply that domestic policy and paul ryan wants to spearhead that and so that's the idea. but it is a far stretch from the 29 days ago of taking this principled stand where i'm not there yet. apparently he is now. >> and 23 days ago when they had that private powwow, the two of them yet to be seen officially together. luke, thanks so much. a quick programming note right here at the top of the hour, andrea mitchell will be joined by senate majority leader mitch mcconnell for reaction on ryan's endorsement. that's at noon eastern right here on "msnbc live." in trump's own words hillary clinton issues new attacks by pulling unedited quotes from the gop nominee. is this her strategy moving forward? also trump's ramped-up

attacks on that federal judge overseeing the case against trump university, claiming race is playing a role. plus, tragedy in texas. the search for survivors even as we speak. four soldiers unaccounted for right now after being swept away by flash floods. we're getting some new information and we are live in ft. hood ahead. innovative sonicare technology with up to 27% more brush movements versus oral b. get healthier gums in 2 weeks guaranteed. innovation and you. philips sonicare. save when you buy the most loved rechargeable toothbrush brand in america.

clinton quoted trump's past statements almost word for word while making her case that he's temperamentally unfit to be commander in chief. here's a listen. >> he says he doesn't have to listen to our generals or admirals, our ambassadors and other high officials because he has, quote, a very good brain. he also said i know more about isis than the generals do. believe me. >> i know more about isis than the generals do, believe me. >> who are you consulting with consistently so that you're ready on day one? >> i'm speaking with myself, number one, because i have a very good brain and i've said a lot of things. >> this is a man who said that more countries should have nuclear weapons, including saudi arabia. >> we're better off, frankly, if south korea is going to start to protect itself. >> saudi arabia nuclear weapons? >> saudi arabia, absolutely. >> this is someone who has threatened to abandon our allies

at nato. >> we don't need nato? >> no. we don't really need nato in its current form. >> he has said that he would order our military to carry out torture and the murder of civilians who are related to suspected terrorists, even though those are war crimes. >> with the terrorists, you have to take out their families. when you get these terrorists, you have to take out their families. >> and don't tell me it doesn't work. torture works, okay, folks? torture works, believe me. >> what would you do as commander in chief if the u.s. military refused to carry out those orders? >> they won't refuse. they're not going to refuse me, believe me. >> that montage first put together by the team at the rachel maddow show. joining me now is joy reid and republican strategist susan del percio. joy and susan, detly number of the ask you, susan, we'll start with you, trump says that clinton is making things up,

that she's not honest. but we just played the tape. clinton deliberately used his own words against him yesterday. how does trump push back against all these comments that he's made publicly on national television. >> what's amazing is that he didn't seem prepared for all of these comments to be made. we alrdy saw that one of hillary clinton's super pac used his own words when it came to women. he said he got an advanced copy of the speech. he should have known where hillary clinton was going. trump should have had his surrogates ready to attack. they seem to be caught completely flat-footed. and him demeaning her by saying she doesn't look presidential is not good enough. he was really ill prepared to respond to this speech. >> joy, i think a lot of people have different opinions about this, but the sort of side-by-side of donald trump in san jose to hillary clinton earlier in the day, i think in the eyes of a lot of analysts made her in effect seem big and trump seem smaller in his attacks because she, and this is something she struggled with

before, she seemed to have a sort of broader, more presidential vision, it would almost seem, whereas donald trump was attacking her for things like e-mails, but not directly directly combatting the topic of the day. >> yeah, and i think what what hillary clinton did so effectively in that speech yesterday was to diminish donald trump. to diminish him in several ways. one of them small and subtle. there is this conceit that has taken hold of calling donald trump mr. trump but calling hillary clinton, hillary or bernie sanders bernie. throughout that speech she just called him donald. she didn't give him that honorific that everyone applies only to him, she reduced him back down to just donald and then she essentially ridiculed the thing he said by just repeating them and invoking laughter from the crowd. when you repeat a phrase and it's laughter, he's instantly diminished. i think what we're seeing is a

preview of the way that hillary clinton will debate donald trump on stage. if they are standing side by side and she repeats back his statements that show his complete ignorance of foreign policy or statements that can be deemed dangerous and he responds by trying to use one of his trumpisms, right, making fun of her or belittling her, he's going to look even smaller. >> the sassiness was kind of striking. one thing to stuck to me is when she said, you know, he likes to tweet. i'm sure he's tweeting about this speech right now. of course he was. susan, here's what former george w. bush chief of staff andy card had to say about donald trump last night. this was also striking. take a listen. >> i'll be honest with you, i can't imagine donald trump being the president of the united states the way he's been acting. so, no, i think a real president has to do a very different job than the one that donald trump is demonstrating that he thinks he could do as president.

>> we've talked about the holdouts that still exist, including both former presidents bush, including one of the bushes for whom andy card worked for in the past. the question is do you think that maybe clinton's speech reaches or perhaps was intended for the ears not just of her supporters but of those republicans who have been nursing those doubts about trump as their nominee. >> that was a startling difference in yesterday between the two campaigns. you had hillary clinton who was at least trying to broaden her support. whereas donald trump in his response was only going to the core of the republican support. he's not looking at this point to expand that. and to mr. card's point, the other thing is, is that right now donald trump is looking for donors. he needs to get -- raise a billion dollars. donors are not going to be responsive to these small, trite responses. he needs to step up his game and show that he can be presidential. >> joy, i want to ask you if i can before we go about those ugly scenes we saw last night in san jose. donald trump condemning them.

jon podesta one of the top aides to hillary clinton condemning them as well. if we were hoping for a unifying campaign, this certainly is not it. is there any chance going forward that either one of these candidates when elected president will be able to do anything that changes the sort of divisions that we already witnessed not just in washington but across this country? >> no. i think the divisions are built in. and if hillary clinton becomes president, those angry supporters of donald trump, the core of his supporters who, quite frankly, have at times been violent at his rallies with him egging them on, they're going to be even angrier if a woman named clinton is the president of the united states. that rage will only increase. and if donald trump were to win, it would embolden his supporters and it would embolden his detractors, embolden the people who feel like they have to bodily resist what he is and what he represents in terms of this ethno nationalist candidate. either way we're headed for

rough waters next year. >> joy and susan, both of you, i appreciate it. thank you. >> thank you. still to come right here, trump versus the trump university lawsuit judge. but next the latest from texas in the search for those four missing soldiers. they were swept away in flash floods. we're live in ft. hood next with the latest on that effort. >> important message for women and men ages 50 to 85. please write down this toll-free number now. right now, in areas like yours, people are receiving this free information kit for guaranteed acceptance life insurance

search at this point given the massive floodwaters throughout that area. >> reporter: hi there, peter, good morning. yes, the search effort is under way and right now as you mentioned five soldiers have been found dead, three others are hospitalized. in a news conference a short time ago, military officials said that it could be possible that those three that are hospitalized, they're in stable condition but they could be released later today. but that search is ongoing for those four others who are still missing. right now the search operation is undergoing behind me inside ft. hood. this of course is a massive military base. this is what military officials are calling a heartbreaking accident. it happened just before noon yesterday in the northeast portion of the base in a very rugged terrain. so that is the challenge right now. they have units, they have boats right now as well as helicopters searching that area. and earlier today military commander spoke about what this has done to this community.

it's really shaken this community. here's what they had to say. >> our priority has been, since the first report of this incident and continues to be the search for our four missing teammates. i'd also like to thank had community for their outpouring of support, their thoughts and prayers. they will be needed in the tough days ahead. >> reporter: now, this unit had just returned from a deployment in south korea just a few months ago. the names of the soldiers impacted by this have not yet been released. they're going to have to wait until next of kin is notified and wait at least another 24 hours. some new information that we found out this morning is that this really -- this whole scenario really shows the power of these floodwaters in texas. local authorities were in the process of closing down some of these roads. some of this base is accessible by public roads. they were in the process of closing down those roads.

before they could do that, that's when this tactical vehicle was overtaken by this fl floodwater. again, the search is ongoing for those four missing soldiers. >> we're just seeing some of the pictures from the floodwaters there in texas. gabe, we appreciate that report. that's an awful story. next up, back to politics. a deeper look at trump's legal battles. the presumptive republican nominee renewing attacks on the federal judge overseeing the class action suits against trump university, now claiming race is playing a role. >> the judge, who happens to be, we believe, mexican, which is great. what judge curiel is doing is a total disgrace. after a long day,

dave stops working, but his aleve doesn't. because aleve can last 4 hours longer than tylenol 8 hour. what will you do with your aleve hours? right. in. your. stomach! watch this!... >>yikes, that ice cream was messing with you, wasn't it? try lactaid, it's real ice cream, without that annoying lactose. lactaid. it's the milk that doesn't mess with you.

donald trump is escalating his attacks on the federal judge overseeing the fraud lawsuits against trump university. trump telling "the wall street journal" that indiana-born judge

gonzalo curiel's mexican harr heritage presents an absolute conflict. i'm building a wall, it's a conflict of interest. trump has called for the judge to recuse himself and said he may file a complaint. court documents were unsealed after trump called curiel a hater and totally biased. joining me now is the president and ceo of voter latino, maria teresa kumar. nice to see you right now. the clinton campaign responded to trump's latest attack with a statement, we'll put it up on screen, that reads the fact that donald trump doesn't see judge curiel and his family as americans makes him unfit to be president of this great nation, a nation of immigrants. in trump's version of america, this latino family isn't really american. is trump's latest line of attack against this latest judge likely to hit a nerve with many latinos? that's the question many are asking. mitt romney lost latinos 71-27%. the unfavorable rating for

donald trump with latinos is in the 80s, like 84%. is this something donald trump can boston over tsoften over th the summer? >> the difference between donald trump and mitt romney is mitt romney was basically saying we want you to self-deport. we're going to make your community so uncomfortable you'll pack your bags and leave. under the donald trump platform, what he's saying is he's blanketing a whole group of americans and trying to make them the other and really creating an uncomfortable situation. the fact that he's going after a federal judge and not only is trying to undermine him because he's trying to use mexican in this case as a slur and undermine his ability to be a fair and balanced institution as a federal judge, he's also threatening the judge saying if i become president, you had better watch out. i've never seen a presidential candidate go after a federal judge trying to undermine one of our basic institutions when it comes to the justice department. it's pretty serious. >> maria, broadly speaking, the

trump people, donald trump himself will say the latino community in america is not monolithic and not focused on one topic. the jobs, which he insists is one of the strongest assets, today hitting president obama who what was only a 38,000 number in terms of the new jobs from last month. so is it possible that many latino americans, not necessarily those who are speaking as publicly and showing up at protests like those at san jose yesterday may say, you know what, our priority is jobs and at the end of the day we believe donald trump is the one who can get that done? >> under most circumstances if that was the platform that he was trying to appeal to not just the latino community but the american community, he may have a shot. but let's look at the laundry list of the republicans who are now saying they cannot support him who are hispanic. you have susana martinez, the secretary of treasury. >> of susana martinez, he said i like her. >> it's a little too late.

well, and then you have the press secretary from the rnc that stepped down saying she just was not comfortable. this is not about policy, peter, this is more of people in the latino community feeling now unsafe. they're feeling less than american. you have parents basically contacting voter latino through myspace, twitter, through letters saying my kids are coming home crying because they're saying under a donald trump administration, their classmates are saying we're going to be deported. this is not about policy, it's all about the tone and how people are feeling they are under fire. what i keep telling protesters, protest peacefully but don't take the bait. he wants to peg the latino community as being anti-american and that is not the case. the first person that died in an iraq war is an undocumented latino who sacrificed his life for this country. let's not try to fall into that trap. if anything, it's spewing, it's anti-american. >> let's look down ballot,

obviously, it's not just the presidential race. we've got the supreme court, congress and the white house all up for grabs right now. the impact down ballot come november will be what? >> the fact that he has to win in really tight electoral races where the latino vote can make the difference, and i'm talking about the rust belt, ohio, between the latino vote and the asian-american vote it's 3.5%. obama won ohio by 2.5%. when we're talking about margins and you're going after a community with their back against the wall, they are starting to register in record number and you're seeing the same uptick not only in the latino community but the asian community and muslim community because they realize the best way to flex their muscles is in the polls. you're going to see a lot of republican senators that will try to step back away from donald trump because it's not good for their brand. >> nonetheless, he's divide conventional wisdom throughout the course of this campaign. always nice to speak to you, thank you very much. >> thank you, peter.

the loss of a legend. the medical examiner's report on prince now out shedding new light on what claimed the pop star's life. what happens next in this investigation. we'll take you there live. more on the powerful drug found in prince's system when we come back. to folks out there whose diabetic nerve pain...

shoots and burns its way into your day, i hear you. to everyone with this pain that makes ordinary tasks extraordinarily painful, i hear you. make sure your doctor hears you too! i hear you because i was there when my dad suffered with diabetic nerve pain. if you have diabetes and burning, shooting pain in your feet or hands, don't suffer in silence! step on up and ask your doctor about diabetic nerve pain. tell 'em cedric sent you.

sir, this alien life form at an alarming rate. growing fast, you say? we can't contain it any long... oh! you know, that reminds me of how geico's been the fastest-growing auto insurer

for over 10 years straight. over ten years? mhm, geico's the company your friends and neighbors trust. and deservedly so. indeed. geico. expect great savings and a whole lot more. nearly six weeks after prince's death, finally some answers. the medical examiner's report says the music legend died from an accidental opioid overdose, specifically the pain killer called fentanyl. it's a drug more powerful than street heroin. stephanie gosk is in minnesota today with more. stephanie, what else did we learn from the medical examiner's report? first of all, this is a drug that's far more prevalent than most americans knew. >> reporter: yeah, it is. it may be a strange name to a lot of people, but it's certainly not a strange name to law enforcement. just in march, peter, the dea sent out this nationwide alert about fentanyl, calling on law

enforcement to keep an eye out for illegal sales on the street, that there had been a spike in fatal overdoses. now that drug getting a lot of attention and scrutiny. it falls under this larger umbrella of opioids. typically if it's prescribed legally by doctors, that prescription happens in a hospital and it's often for extreme pain. if you consider cancer patients in the last stages of a terminal disease. it is not prescribed often for people to take out of the hospital and go home with, for instance. however, law enforcement that i spoke to today in minneapolis say they haven't seen a huge uptick in fentanyl on the streets of their city but it's becoming a problem. >> let me ask this investigation more broadly. where does it stand right now? does the potential for criminal charges still exist, going back to how prince would have gotten access to these opioids? >> reporter: the investigation is still active.

actually there is evidence of that today. we have police here at paisley park today, even though most of the memorial has been taken down. you don't see as many visitors here. there are police here. they were searching cars going in. we're not entirely sure what's going on but it remains the big question, and that is will there be criminal charges. where did the fentanyl come from? was it legally prescribed? we've heard mention of two doctors, one doctor out in california, an addiction specialist, dr. howard cornfeld. his attorney says that he was not directly involved in any treatment with prince. there's also a local doctor here, dr. mark schulenberg who was providing treatment to prince but a person who's close to the doctor and is familiar with that treatment said he never prescribed opioids but instead was prescribing things to help with withdrawal from opioids. all of this shining a light on what is an incredible problem in this country, as you know. people getting hooked on pain killers and this sliding progression towards reasonably

risk-free drugs towards those that are very dangerous and fentanyl is really the most dangerous of the group. >> steph, let me circle back to one thing. i hadn't heard that there were police investigators back at the home in paisley park again today. have we seen them in recent days? it's obviously a new situation there. i guess there's probably little information in terms of what they're looking for, but the fact that they're checking vehicles as they go in and out is interesting as well. >> reporter: yeah, it is. we weren't here in the morning yesterday. i'm not sure in the last couple of weeks whether they have been showing up here. we know that there have been searches in the last month or so, repeated searches of the home, and i would stress that we don't know what they're doing here today. just the fact that they are here alone and searching cars is strange. it's just a reminder again that this investigation is active and that everyone wants to know whether there could be criminal charges here. >> no doubt. of course the attorneys for both

of the doctors we were talking about here deny wrongdoing at this time. stephanie gosk in minnesota, stephanie, thank you very much. i want to bring in forensic pathologist cyril wecht, one of the most respected pathologists in the country. i very much appreciate your time. can you give us a sense, we were talking about this, how in simple language can you explain to americans what fentanyl is and how it relates to heroin. someone just said it's like heroin on steroids. >> it's a powerful synthetic opioid that was introduced in the early 1960s. it's about 50 times as strong as morphine, as heroin and 100 times as strong as morphine. it is rarely, rarely prescribed for people outside of hospitals or other medical facilities. it is usually used in conjunction with an anesthetic agent for people in great pain

from a surgical procedure. the drug fentanyl is being found more and more on the street. the great number of drug deaths i do every year, in the hundreds, the increase of fentanyl-related deaths has risen markedly. about four or five years ago, there were about 618 such deaths reported. last year, about 4,500, a 7.5 increase. it is a drug that is acquired illicitly for the most part because of what i've said, doctors are not prescribing it very, very often, in fact rarely. and it is mixed many times with morphine or heroin or other drugs and people may not even be aware of the fact that it's fentanyl. we do not know because we don't have a complete talks logical report or post mortem report what was involved.

i believe the drugs probably were mixed with the fentanyl. and we'll probably not learn anything much more. i don't believe any charges are going to be brought against physicians because, as we have been told, nothing indicates that drug was prescribed for prince. we don't know how much fentanyl was in his system. >> no, when you think of fentanyl, sometimes it has a delay reaction and kicks in later and sometimes it is short

lived and people don't think they get the effect and they take it again. it is a dangerous job and it is predictability of it. >> incidents of over doses were at an alarming rate throughout this country and a lot of americans having their eyes opened up to this epidemic effect. doctor, thank you, we appreciate your time. >> straight ahead, will the parent be charged after their three years old son fell in the gorilla exhibit. the prosecutor expected to announce the decision on monday. what the cincinnati zoo is doing to ensure safety. that's next. id it. when the insurance institute for highway safety tested front crash prevention nobody beat subaru models with eyesight. not toyota. not ford or any other brand.
