but couldn't revive him. day four of the prosecution's case, and continued attempts, by the defense, to suggest that floyd was a potential threat. ready to spring back up, somehow, and do harm. the latest, tonight, from cnn's omar jimenez, in minneapolis. >> reporter: the moments, when paramedics arrived and george floyd appeared unresponsive in may, 2020, are coming into clear focus. an audio played in court. derek chauvin is heard on the phone describing what had just happened. >> had to hold the guy down. he was -- was going crazy. wouldn't -- wouldn't go in the back of the squad. >> reporter: he was talking to the supervising-police sergeant on duty, at the time, david pluger. >> do you have an opinion, as to when the restraint of mr. floyd should have ended, in this encounter? >> yes. >> what is it? >> when mr. floyd was no longer offering up any resistance to the officers, they could have ended their restraint. >> and that was after he was handcuffed and on the ground, and no longer resistant? >> correct. >> reporter: paramedic and derrick smith responded to the scene and arrived to an unresponsive floyd. smith, seen here checking floyd for vitals. >> did not detect a pulse. >> and what did his condition appear to be, to you, overall? >> in lay terms, i thought he was dead. >> reporter: the checking began while now-former officer, derek chauvin, still had his knee on floyd's neck. before bravender stepped in. >> what were you attempting to do, at that point in time? >> just tell the officer to move. >> and why did you need the officer to move? >> so we could move the patient because he -- he was, i guess, limp would be the best description. >> he testified a cardiac monitor showed floyd's heart had flatlined. >> wasn't really doing anything, at that moment. >> reporter: during cross examination, the defense asked about whether overdose patients can regain consciouseness and b aggressive. >> have you personally seen that happen? >> yes. >> reporter: but testimony thursday also touched on who george floyd was, before may, 2020. >> he loved playing sports with, like, neighborhood kids. >> reporter: courtney ross, george floyd's girlfriend of three years, took the stand. the first testimony heard from someone who knew floyd. >> we went out to eat, a lot. >> why? >> because floyd loved to eat a lot. he's a big man and, you know, it took a lot of energy to keep him going, and he loved food, and so did i. it was -- it was fun. it was an adventure, always, with him. >> reporter: but while emotional, throughout, she testified their relationship, also, included addiction to opioids. >> the classic story of how many people get addicted to opioids. >> did he have sports injuries that he complained of? >> yes. his neck and it -- it -- down from his neck to shoulder blade and down to his lower back. >> reporter: the defense for derek chauvin is trying to make the case, it was drugs in george floyd's system that killed him, not chauvin's knee to the neck. so, when it was their turn to question ross, they asked about an emergency trip to the hospital, floyd had, just two months before his death. >> did you later learn that, that was due to an overdose? >> yes. >> and did you learn what that -- what caused that overdose? >> no. >> at that time fframe, did you learn that mr. floyd was taking anything, other than opioids? >> no. >> you did not know that he had taken heroin, at that time? >> no. >> reporter: she testified, days before he died, floyd was using again but never complained of shortness of breath or difficulty breathing. >> had mr. floyd been an active person, physically? >> yes. he's very active. >> omar jimenez joins us now and, omar, quite a day in that courtroom. what can we expect when the trial gets under way, again, tomorrow? >> well, for starters, we are going to have a brand new witness, starting tomorrow. but the court has been withholding the identities of these witnesses, for security purposes. at some point in the future, though, it is expected that current-minneapolis police chief, the medical examiner, and even members of floyd family, are expected to testify. and really, over the course of this week, what we've seen with this testimony are puzzle pieces that have come together, to paint a clear picture of what happened on may 25th, 2020. you take yesterday, for example. we got a clear picture of what happened when the ambulance left. and what happened before police were initially called. today, it centered on context around any-prior george floyd drug use. also, that when medical personnel got there, they believed, for all intents and purposes, that george floyd was dead. and then, the supervisory sergeant, at the time, for derek chauvin, saying definitively when he was pressed by prosecutors, that he believes derek chauvin used excessive force on george floyd. >> yeah. that moment, notable, no question. omar jimenez, thanks very much. let us a bring in our legal and law enforcement team. cnn legal analyst. laura coates. he is a criminal defense attorney. she is a former prosecutor. also, charles ramsey, former top cop in d.c. and philadelphia. welcome to all of you. laura, i do want to begin with the testimony from derek chauvin's supervisor, his sergeant. him saying -- i mean, he said, in no uncertain terms, that the force applied by chauvin, the knee in the neck, should have stopped when floyd was no longer resisting. this contradicts the defense, to this point, saying that he was just following training. how critical was that testimony? >> this was extraordinarily critical, to have somebody who is in law enforcement. his supervisor, to really debunk this myth that he was perpetuating, so far. which is that you are able to use force, even after any force is being used against you. remember, this is about the idea of whether an officer can use a reasonable amount of force to stop whatever perceived threat is against them. once that perceived threat is essentially neutralized, then you have to reassess and act differently. and so, the idea of, not only the use of force, which may have been justified, initially, you have to go all the way down the timeline. and figure out does it become assault? does it become excessive once the threat has been neutralized? does this, then, become unreasonable to continue and sustain this force? this was extraordinary testimony here, today. and really, it shouldn't come as a surprise because, remember, chauvin was fired, very quickly after they realized this because it was conduct really unbecoming of a police officer in minneapolis or anywhere. >> mark, you have defended folks, in court. what -- what's the defense's possible response to that? that this is chauvin's police sergeant, saying it should've stopped. there's nothing, in the training, that justified keeping his knee on floyd's neck. well, what's the defense's potential response to that? >> well,l, what they have to dos try and focus on the stress of the moment. that, even though chauvin, looking at him, in the cold light of day afterwards, may not have done the right thing. they have to focus on the fact of what he was perceiving, at the time that he was doing what he did. we can, very easily, look at it and say there is no way that's justified. and what i think is very compelling, as laura just said, is when you have an on-the-ground officer. the -- the supervising officer, come down and say, i look at that and i say, no good. that's very compelling to a jury because now they have another officer saying it. there is going to be a fight, back and forth, of the use-of-force experts that i presume are going to be called. but when you have the very supervisor saying it shouldn't happen. and here is something else, i thought, jim, was very important. the way chauvin said and he explained his behavior by saying he was acting crazy. it seems, as though, that's now his perception he is trying to give to a supervising officer. when everyone who saw that tape knows that for at-least-six minutes, if not more, he wasn't acting crazy. and that's exactly what the problem with the continued use of force is it's got to drop back down, as the threat does. >> that was notable. and chief ramsey, the other thing, notable, about chauvin's communications to his supervisor, immediately after the incident. chauvin, notably, did not mention that he had placed his knee on floyd's neck to restrain him, for minutes. as the tape shows and as the eyewitnesses. is that a piece of information that you, for instance, would expect a police officer, serving under you, to share with you, in the aftermath? >> well, i would. but he is trying to cover himself, at this point in time, clearly, when he is talking to his sergeant. the reality of what just took place may not have really hit him, yet. because this -- this stuff's on video. it's on audiotape. and so, you know, it doesn't make any sense to try to alter the story, when it's right there. and so, at that moment, it seems, to me, like, when he is speaking with the sergeant, he is trying to justify use of force that's simply unjustifiable. >> laura coates, the other, big piece of the testimony, today, was really multiple accounts and questions about george floyd's drug use, up to this. even the prosecution, right, discussing with his -- his girlfriend, that they were both opioid addicts. she said it very openly. something he and she struggled with and, also, establishing that he had other problems with drugs, including just two months before, an emergency trip to the hospital for an overdose from -- from heroin. i wonder. from the defensive -- defense's perspective here, is that primarily about an attempt at character assassination, right? calling into question, questions about the victim here. or is there something else going on here, about raising questions about what could have caused his death, right? or at least, a reasonable doubt about what could have caused his death? >> it, likely, is more of the latter because, of course, the way people think about opioid abuse and addiction is a different time that we are in now, in 2021. the idea of being an addict is not the vilifying factor that, perhaps, it may have been in character assassination years ago for a defend or a victim in a crime. and so, they have already talked about the characterization of that. and remember, it was the prosecution who fronted this because they want to be able to take the wind out of the sails of any defense argument to say, ah-ha, this is what they don't want you to know. why didn't they tell you this? if they didn't tell you that, what other things aren't they telling you? but ultimately, this is going to come down to two questions. number one, whether the use of force sustained over a period of time was reasonable. and number two, whether kneeling on the neck was a substantial-causal factor in his death. remember, in minnesota, jim, it need not be the sole factor in the death but has to be a substantial-causal factor. so probably, try and set the groundwork that says, hey, we know the knee was on the neck. but he had drugs in his system. that was the one that was the substantial-causal factor, not the knee to the neck. they are trying to lay the groundwork, now. so far, unsuccessfully. >> mark, these are human stories, right? juries are made up of -- they are a jury of our peers. fellow human beings with sympat witnesses, right? and -- and -- and you saw the accounts there, sometimes tearful, from george floyd's girlfriend describing him as a man with a lot of interests, and as a loving partner, and so on. i just wonder. you have been in the courtroom, right? you know, as -- as a defense attorney. as you watched that today, did you see that as -- as powerful, for the prosecution? >> i thought it's very, very powerful. i think, everything that the prosecution has done, so far, has been by plan and has been effective. again, this -- this is their best day, right? these last four days. and the future couple because it's their presentation. but i thought the idea of the way they presented it. first, with people who sort of knew george floyd, a little bit. then, gave the scene. and now, from the girlfriend. i think, it was very, very powerful because exactly what they want to do is to personalize that victim. and i do think that the defense has to be more careful. i think, the idea of sort of going after these witnesses with almost-a-shotgun approach, they need to be more focused on what their defense really is, if they are going to attack cause of death. do it, but leave the witnesses, like even the girlfriend, out of the crosshairs. >> yeah. i -- i -- i get that point because you don't want to antagonize. chief ramsey, from your perspective, do you believe that derek chauvin owes it not just to floyd's family, citizens of minnesota, but also, to the law-enforcement community? to take the stand, at some point, in this trial and testify? do you believe -- do you believe that? >> i don't know. i think it will go based on whatever his attorney tells him to do. so, whether he testifies, or not, i really don't know. i'd, personally, be surprised if he did, under the circumstances. but if i could mention just one thing that i thought was curious, and that's when the defense brought up the issue of the critical decision-making model that's used in police training regarding use of force. it really is replacing the old use-of-force continuum that we used to use. and the use of force -- rather, the critical-decision-making model is one that really forces officers to constantly reassess their actions, based on the changed behavior of the suspect. which can either escalate or deescalate, obviously. but you have to constantly reassess, reassess, reassess. just because force was justified, at one point, doesn't mean it's justified later because you have to reassess. what's he doing? what's the threat? and if the threat's not there, stop. >> yeah. it's a great point and that goes back to where we started, right? the sergeant, chauvin's sergeant, saying it should have stopped because floyd was no longer resisting. listen. charles ramsey, mark, laura coates, good having you on again tonight. coming up. the congresswoman hoping to reform policing and redeem justice in the wake of this tragedy. sheila jackson lee, she is going to join us. later, as if the sex-trafficking allegations and blackmail claims were not enough, there is, yet, more breaking news. shocking developments in the congressman matt gaetz' story. this is gary, i invested in invesco qqq. a fund that invests in the innovations of the nasdaq-100. like this artificially intelligent home system. become an agent of innovation with invesco qqq. ♪ not everybody wants the same thing. become an agent of innovation with invesco qqq. that's why i go with liberty mutual — they customize my car insurance so i only pay for what i need.

the first who said, send me, was george floyd. >> congresswoman sheila jackson lee joins us, now. congresswoman, thanks so much for taking the time, tonight. >> thank you, jim, for having me, this evening. >> you, of course, authored the george floyd justice in policing act. and i want to talk about that, in -- in a -- in a moment. but, first, your reaction, as you have watched these first few days of the derek-chauvin trial? you know, even, for instance, to see a moment you reference there at his funeral, him calling for his mother, in his final moments. >> well, jim, i think we want what every american should want, as we watch this trial. and as i say that, african-americans, people of good will, that is justice, and a recognition that we are a country of law and order. but as i have heard police officers say, they want to go home to their families. and i've added, and we want to go home to ours. this officer chauvin did not allow george floyd, who was loved by so many, as we have seen in the midst of his death, to go home to his family. whether it was in minneapolis or whether it was in houston, texas, or places beyond. and for that, we believe, that officer chauvin should be held accountable. i think, what we have seen is a block-by-block building of a story, and a physical structure. and i think it's been strong. i believe the prosecutors have carefully laid out, with eyewitness testimony, with video. and then, i'd highlight today. yesterday, a very emotional day. showing that the persons, that were standing around, who came around, they were not intimidating to the police. they were hurt. and they were concerned. i think, the prosecutor has laid this out. and i think it's up to the jury, to see the facts, as clearly as they can. and to match that with the law. >> we'll be watching. so, the bill you named, in memory of george floyd, it passed the house. the history of cases, like this and there is no case exactly like george floyd. but as you know, we have seen what appeared to be excessive force by police, and not issued in a punished in a court because the law is written in such a way that it's hard to do. i wonder, if you could explain what the bill, that -- that you have brought forward does to attempt to change that? >> jim, the power of this bill is the massive support it's gotten in the leadership of the congressional black caucus that worked, extensively, with all of us on this legislation. >> uh-huh. >> and, in this elegislation, w are fair. how are we fair? one, we look at the chokehold, which the emt/ems operators told us when they arrived they thought he was dead. why? because officer chauvin used excessive force. and used, in sessence, a choke-hold form of -- of -- of action against george floyd. and he went beyond, even, the training and actions of minneapolis police. so, we outlaw that, period. we outlaw the no-knock warrant, if you will. that killed breonna taylor. we end racial profiling, that, in essence, put sandra bland in jeopardy. we provide a massive formula for training police officers, and ending excessive force. and we, also, indicate that, if, by chance, you are a victim or your family has lost a loved one, you have an equal chance, in the court of law, just as a police officer. you can be fairly heard, as a victim. just as the officer can be heard. and i think this is very important. >> there was a moment, following the depth of the floyd protests last summer, when there was some bipartisan support for some police reform. the two parties did not come to agreement. do you have republican support? have you -- have you spoken to republicans, as you lobby for this? and, of course, i know the senate is the next step. do you think that's possible, in this moment? >> you know, if anyone is looking at this trial, i hope that their hearts and minds have been as much touched, during the trial, as it was touched, i believe, in the aftermath of the killing of george floyd. the murder of george floyd. and so, we may not have vocal-republican support. there are discussions going on. but i tell you what we do have. we have an executive order that donald trump wrote or his administration wrote. that really had a large part of some of the aspects of the george floyd justice in policing act. i would ask my republican colleagues, who were so enamored with the past president, whether or not, now, they reject those elements, that they were willing to support in an executive order. the legislation, that has been promoted by our friend, senator scott, is not where it needs to be. it's not strong. doesn't have the strength that we need. but the table, the chairs, are still there, jim. and i believe, at this time in history, it will be good for america if we can resolve these issues. and have a coming together. to recognize that this nation is a nation of law and order. but it is, also, a nation of humanity and compassion and justice. and that's what the george floyd justice in policing act represents. >> we'll be watching. representative sheila jackson lee, thanks so much for joining us, tonight. >> thank you, for having me. >> and coming up, next, this hour. a story that still has more remarkable, even alarming, twists to it. new allegations, in the federal investigation involving republican firebrand and congressman matt gaetz. details. there are a lot of them, coming up. cal: we've saved our money, and now we get to spend it our way. val: but we worry if we have enough to last. for retirement planning, investment advice, and more, look for a cfp® professional. cfp® professionals can help you craft a complete financial plan that gives you confidence today and tomorrow. find your cfp® professional at letsmakeaplan.org. cal: our confident forever plan is possible with a cfp® professional. ♪ hi guys! check out this side right here. with a cfp® professional. what'd you do?

>> exactly. cnn has learned they are two entirely-separate cases. we have obtained documents that if you are to corroborate that someone with seemingly no-direct connection to the sex-trafficking case offered to make the lawmaker's legal troubles go away, in exchange for money. we have also obtained e-mails that confirm gaetz's father is cooperating with the government to investigate that effort. but it's important to note, as you pointed out, gaetz was a staunch supporter of former-president trump. but this sex-trafficking investigation began in the final months of the trump administration. and with his political future on the line, he -- gaetz is trying to conflate the two cases. reframing himself as the victim. and distancing himself from the seriousness of the allegations he faces. >> and -- and under bill barr and bill barr got briefed on this investigation. pa paula reid, thanks so much for your reporting. well, a great many, late-breaking developments. perspective now from the former u.s. attorney for the southern district of new york and cnn senior-legal analyst. it's great to have you on. i was trying to keep a running tab of all the the alleged wrongdoing here, because there is the idea of a sexual relationship with an underaged girl. trafficking. misuse of campaign funds in -- in some sort of involvement with these young women. fake i.d.s. a fake-i.d. scheme. allegations of prostitution. allegations of use of drugs. i mean, that is a long list. can -- can you help us prioritize those? or is any one more serious, than the other? >> they are all pretty serious and i think you have a good tab on it, jim. i think, what will really matter is which things can be proved. i mean, at this point, you have a lot of reporting. some of it seems to be credible reporting. i think, one of the biggest problems matt gaetz faces, as was alluded to in the report. there is a person who is already under indictment for sex trafficking and other charges, joel greenberg. and i haven't seen any reporting to this effect. but you have to, you know, wonder, whether or not this person, who is facing lengthy-prison time, potentially, if convicted, has flipped. has become a cooperating witness, against congressman matt gaetz. that means, then, that if he -- if he takes that position and becomes a cooperating witness, that he is in a position to give very powerful evidence to the government. to bring charges against matt gaetz, relating to the stuff that he is involved in. so, i think, when you -- when you try to think of where there's most jeopardy, i don't necessarily look at, you know, which potential crime carries the longest prison sentence. which particular crime carries the most potential evidence in the form of cooperating witness testimony or other things? >> understood. and listen. as you know, a prosecutor, they look for cooperators. it helps them build their case. help me understand, the seriousness of an investigation like this. and we should note, it's an investigation. nothing has been charged, yet. perhaps, you don't find su sufficient evidence. but it's been going on for a number of months. and by the way, it started under bill barr, in the trump administration, despite the fact that gaetz, a trump ally, and barr was briefed on it. given that and given that the investigation to cnn's reporting continues, how serious does it make that investigation? >> i think it's quite serious. it's interesting to -- to note that all this information is coming to right now. i'm not sure why there are leaks going on. there was the case my own office oversaw a few years ago that had far-reaching implications, in another regard. but the case against congressman anthony wiener was a serious one with respect to a minor. these are cases both because it involves minors, and also, because the targets of the investigation, are people who have sworn an oath to uphold the constitution and -- and -- and -- and -- and are supposed to be beyond reproach. so, i think, they take it seriously. i think, they, also, want to make sure that they get everything right. you don't accuse a sitting member of congress, unless you have all your ts crossed and your is dotted and that's what they are going to be doing here. and a few months is not a long time, in connection with this kind of thing. it may be the case, as you point out with your long litany of potential investigations, they want to square away lots of different thins before they decide what to do with respect to charging. >> understood. this claim by congressman gaetz that his family was the victim of an extortion attempt. and again, not in relation to the target of this investigation, itself, but it seems, the information that it exists. what -- what do you make of that? i mean, clearly, that is being investigated. that's cnn's reporting. surprising to you? bizarre to you? >> yes, it's all bizarre. i mean, i tweeted the other night, when matt gaetz made his statements and this is something that used to be my bread and butter. you know, it is in the heartland of what i understand. accusations made by people under investigation. and i said something like i don't even understand what is going on here. it's very bizarre. and you say, i think, correctly, based on what we know. those two things are unrelated. but it's obviously in the interest of somebody, who is being investigated, to connect them to each other. to, as paula reid said, cast themselves as the victim. and he keeps using the phraseology that he and his family are being extorted by a former department of justice official. making it sound like this department -- this person was at the department of justice, you know, just a few weeks ago, and had something to do with the under underlying investigation. that's not true. this person was a former member of the justice department. and has been gone for two decades, is my understanding. so, it can be simultaneously true that matt gaetz is being investigated for serious sex-trafficking conduct. and separate from that, someone is trying to extort him based on the fact that that's happening. it's unusual but it happens. but they're separate. >> uh-huh. and we should note that former-justice department official does deny that allegation. preet bharara, we will continue to dig. >> thanks, jim. as the pace of vaccinations keeps rising around the country, it's great news. one question remains. how long will the vaccines' protection last?

ongoing-phase-three trial of its coronavirus vaccine confirms the vaccine's protection lasts at least, that's key, at least six months after the second dose. this, as dr. anthony fauci not only agreed with that but says tonight, the protection is likely to last longer. all the while, there are worries about the rise in overall-new infections around the nation. joining me now is dr. leana wen. she

that, dr. wen. but first, let's talk about this pfizer data, here. at least six months. should we look at that as a baseline number, though? because the fact is, that's as much data as we have, at this point, because the vaccine's only been around and tested for -- for six months. is that the right way to look at this? >> that's exactly right, jim. so this is the floor, definitely not the ceiling. >> okay. >> most likely, the prosectecti the vaccine will provide will be years, even, we just don't know that. and i think there's a possibility we may need to get a booster shot. maybe, booster shots that target new variants. but i think that is a small price to pay given that we now have the safe and very effective vaccines that are out there. >> which is not unlike other vaccines where you get boosters, after the fact, to continue the -- the protection. okay. as this is happening, and i always like to -- and you and i talk all the time about the pandemic and i like to accentuate the positive because there is a lot of positive news and more people are getting vaccinated and i got vaccinated, and everybody's happy. but infections are rising because people are just, kind of, giving up, right? in a lot of places. tell us how concerned you are about that, and what your advice to people would be. >> i am very worried, that we are on the precipice of a fourth surge, here. and we are seeing virus-hot spots emerging in different parts of the country. we are seeing that the population of people getting sick are, actually, skewing younger. and in a way, that's good. it means that the older people, who have been vaccinated first, that they are well protected. but i am very concerned act this trend that we're seeing, and my advice for people is to hang in there. please, wait at least until you are fully vaccinated, before you're traveling. before you're engaging in high-risk activities. know that, when you become vaccinated, the activities that were, once, higher risk, are now going to be lower risk. and so, just wait until then. >> yeah. don't -- don't be the last person to get infected, right? i mean, it's almost as simple as that. as i mentioned at the top, you were a participant in the johnson & johnson vaccine trial. you actually found out you received a placebo because that's the way these things work. half the people don't actually get the vaccine but you did get the vaccine yesterday morning. for folks at home who haven't been vaccinated yet, how are you feeling? what are the effects? >> i actually feel just fine, jim. i was pretty convinced, actually, that i had gotten the vaccine, before. so i was in the -- i'm -- i'm still in the -- in the trial. but part of the trial that i was in, was the two-dose johnson & johnson trial. to see if two doses of the vaccine will provide better protection, than one dose. and so, i received two doses of, what turned out, to be a placebo. and then, i found out. so having the opportunity to get the johnson & johnson one dose. so i am now in the one-dose part of the trial to compare that to two doses. i have a mildly sore arm. maybe, i was a little more tired last night. i feel fine, and i actually feel just really grateful that i am protected, myself. and also, that this brings us a little bit closer to getting more people protected in the country. >> exact -- and same for me. the pfizer one and i have a little soreness in the arm. but otherwise, feel like my old self. dr. leana wen, thanks very much to you. >> thank you. you, too. coming up next. how florida republicans are

republicans are in the middle of advancing a controversial anti-riot bill. it's a prerogative of governor ron desantis, and it's his party's answer to last year's black lives matter protests spawned of course by the killing of george floyd. critics say it defines riots far too broadly and could end up impacting legitimate protests. randi kaye has the details. >> i definitely think it's unnecessary. i think it's anti-protest. anti-black lives matter, and it's not for the people. >> reporter: genee tinsley is talking about florida's anti-rioting bill, officially known as hb-1. as a peaceful protester here, she's been watching the progress. it passed the house on march 26th after several hours of spirited debate. >> 76 ayes. >> reporter: and soon the senate will take it up. if it passes, florida governor ron desantis is eager to sign it in law. >> if you are involved in a violent or disorderly assembly and you harm somebody, if you throw a brick and hit a police officer, you're going to jail. >> reporter: that tough talk is exactly what has genee has concerned. >> it gives police more power to potentially abuse it. for them to define or decide what is a riot. >> reporter: critics say it broadly defines a riot that even peaceful protestors would get caught up in arrests. state attorney andrew warren argues the bill criminalized peaceful protests. >> the problem is if you have 100 people in a protest and three of them decide to commit a crime, under this bill, the other 97 are guilty of rioting just for being there. >> reporter: the bill's co-sponsor, republican representative anthony sabbatini says that's not the way it's designed. >> you're not going to see people who are not breaking the law dealt with as if they are violent protestors. >> reporter: the bill includes a mandatory six months sentence for those convicted of battery on police. it also bans the practice of blocking roadways during protests and prohibits the demolition of memorials or statues. and for people arrested for riot-related offenses, the bill requires they be held in jail without bail until their first court hearing. >> these are all scraggly looking antifa types. they get their mug shot taken and then they get released. and it's like a carousel. on and on it goes. that's not going happen here in florida. >> reporter: the bill was announced last september. >> black lives matter! >> reporter: following a summer of nationwide protests in response to the death of george floyd. >> it was george floyd's death that spawned those instances of behavior. but it's just a matter of time before another political event spawns the same behavior for a different cause. >> reporter: sabbatini says florida needs more tools to crack down on violent protesters, but state attorney andrew warren disagrees. >> this anti-protest bill is an unconstitutional waste of time. it tears a couple of corners off the constitution by encroaching on free speech and free assembly. it doesn't even help prosecutors. we already have the tools we need to prosecute people who commit rioting. >> reporter: some see racial undertones in the bill too. >> it targets definitely black people, people that want to change. >> reporter: sabbatini, the co-sponsor, says the bill doesn't target any specific group. >> it is a racially and politically neutral bill, and we're going to keep it that way. >> randi kaye joins us now. randi, i want to get to the root cause here because were the protesters, the floyd protesters in florida actually that violent? therefore warranting a new law like this? >> jim, it really depends on who you can. the cosponsors say absolutely, but the state attorney says definitely not. he points to one night in tampa. in hillsborough county, where his office is, he said one night things got out of control there was some rioting and looting. somebody burned down a sports goods store and that person is charging. he is prosecuting that person and he is prosecuting another 120 people in crimes from that night. his point is they don't need any more laws. they have enough tools right now here in place in florida to do their job. we don't have a date when the senate is going to take this up yet, but that is a republican majority in the florida senate here. they do expect it to pass. >> the state legislators have a lot of power. randi kaye, thanks very much. still to come, the very different look and tone to president biden's cabinet. what their first meeting says about this administration and the last one, when we
