wright. >> and remember yelling, taser, taser, taser and nothing happened. and then he told me i shot him. >> will her tears impact the jury? hello. welcome to "the lead." i'm jake tapper. we begin with breaking news this hour. in fact, we're breaking it for you right now. we are learning more about that text message that former president trump's then chief of staff mark meadows, one that outlined a way to deliver the election to trump before the votes had even finished being counted. three sources tell me and my colleague jamie gangel that members of the bipartisan house select committee investigating the january 6th insurrection believe that former energy secretary and texas governor republican rick perry texted mark meadows november 4th. that's the day after the election. now multiple sources who have perry's phone number and separately databases of phone numbers confirm that the number from which that text was sent, which cnn obtained from a source, that number belongs to rick perry. that unsettling text message sent while votes were still being counted in several states. it said, quote, here's an aggressive strategy. why can't georgia, north carolina, pennsylvania and other republican-controlled state houses declare this is bs, where conflicts in election not called that night and just send their own electors to vote and have it go to scotus, the supreme court of the united states. now a spokesman for rick perry tells us the former governor denies having sent that text. when asked how he explained the fact that the text came from rick perry's phone number, which we confirmed through multiple ways, the spokesman had no explanation. the text message was among more than 6,000 documents that mark meadows turned over to the committee. it was made public on tuesday when democratic congressman and january 6th committee member jamie raskin of maryland read the text on the house floor during debate on whether to hold mark meadows in criminal contempt of congress. raskin cited the text as evidence demonstrating why the committee needed to interview meadows about the events leading up to and on january 6th. >> how did this text influence the planning of mark meadows and donald trump to try to destroy the lawful electoral college majority that had been established by the people of the united states and the states for joe biden? >> we should note raskin mistakenly said on the house floor that it was a house lawmaker who sent the text. they do not believe that it was. they believe it was rick perry, the committee. after cnn reached out for comment, a source close to raskin told us the congressman confirmed he had actually made a mistake and he has now written a letter to correct the congressional record. let's talk more about this with cnn's special correspondent jamie gangel. my partner in this story as always. pleasure working with you. so what do you think is the significance of this text which was sent the day after election day, before many states had even called who won. >> my understanding is this is -- look, there are a lot of important texts the committee has. this is a very important one because it is november 4th. and aggressive, to use the word in the text, to say the least. imagine the election has not been called. the votes have not been counted. and this text message comes to mark meadows basically laying the groundwork to overturn the election. it is hard to imagine how this comes from rick perry is the longest serving governor of texas, three times. he served for two years as energy secretary in trump's cabinet. how this impacted what happened between november 4th and january 6th is going to be key to the committee's work. >> and it's interesting also because we should note the three states he was calling for, it appeared that he picked them, among other reasons, that they had republican legislatures. and one of them, trump went on to win, north carolina. he cites georgia, north carolina, pennsylvania, north carolina trump won. >> but no one was waiting. >> right. >> for the voters to vote. they were ready to go in, send your own electors. ignore the voters. >> and we only have had eyes into a handful of these texts when mark meadows turned over 6,000 documents. >> i think this is a very key point, jake. we know -- you and i have both heard that in other instances where we're seeing text messages, it's not just one text message. we don't know yet, but were there multiple text messages from this phone, how did mark meadows respond to that? and remember again, mark meadows voluntarily handed this over without any claim of privilege to the committee. it's one of the first texts the committee has released. they clearly see it as important. and despite the fact that perry says he didn't author it, we do know it came from his phone, and i'm told that eventually all of these texts will be identified. >> it's easy to deny something through a spokesperson. it's less easy to do so when you're under oath. we should note about governor perry, and this is somebody who in 2015, when he ran for president, he has run for president twice. in 2015, running against trump, he referred to trumpism as a cancer of conservativism and said that that cancer would ultimately corrupt conservative principles and, you know, i mean, the evidence is right there. >> i spoke to some longtime republicans, people who know rick perry very well about this. they could not understand why he would do this, but it does speak to something we've seen over and over again with trump loyalists and that is this text is going around the american people. end of story. >> thank you so much. pleasure working with you on this. i'm sure we'll have more stories on this subject in the future. let's discuss with our panel. s.e. cupp, let me start with you because before the show, you heard me rehearsing. we have three individuals on background and a fourth off the record confirming rick perry's phone number for us. the number that we got from a source familiar with where this text came from. and then why don't you tell people about the conversation you and i just had. >> well, i said, you know, if you want to share the number, i have it as well. i have the number because he emailed me his number to talk about something unrelated. actually about mental health. we had a really interesting, good, nice conversation about mental health just a few months ago. and i corroborated that was the number that he personally gave me. >> yeah. >> so, look, i like rick perry personally, but i think the question of whether it's his number is probably the wrong one. whether somebody got a hold of his phone, i guess is a possibility, but that is rick perry's phone number, the one he gives out. >> what's odd about that also is, obviously, they won't offer an explanation. they just deny it. i didn't write that. >> well, it came from your phone. we've now confirmed the phone number on two different databases and from five people who know you. daniela, we just talked about this with jamie, but this is the same rick perry who said this six years ago. >> let no one be mistaken, donald trump's candidacy is a cancer on conservatism and it must be clearly diagnosed, excised and discarded. it cannot be pacified or ignored. for it will destroy a set of principles. >> it will destroy a set of principles. that's interesting. >> yeah, who knew rick perry was going to end up being quite the soothesayer. it just shows again how deep the rot of trumpism has gone within the party. look, i don't agree with rick perry on probably pretty much anything, but given like what he said during the 2015 election, i never would have guessed he would have become a person who would text mark meadows the day after the election before votes were counted trying to subvert the will of the american people. it's really, really disturbing and it just goes to, again, how important it is to get mark meadows under oath and talk about what happened after he received those text messages. >> s.e., this is a former governor and cabinet secretary generally well regarded. and this week we learned sitting lawmakers, justice department officials, former defense department officials, so many of them in on this attempt to undo the will of the american people. we can't just dismiss this as fringe. just some hair brain scheme among a couple bad apples. how is your own thinking shifted this week from what we've learned? >> well, it was a massive attempt at scamming, rigging, meddling in an election. all the things donald trump has accused other people of doing. all these people were interested in doing. look, democracy was at work while they were suggesting this. democracy was doing its job. the wheels of democracy were turning because the democracy is the counting part. the counting part of the votes, right? you count the votes. that's how you know how -- who won and who voted for whom. before the votes were counted, while democracy was working, all of these people were suggesting a scam, a way to scam and thwart democracy. that is perpetrating a massive fraud on the american people. and i just can't imagine anyone defending this. and i am not surprised rick perry if he authored that, we don't know. if he authored that, i'm not surprised he's denying it. i'd like to hear him denounce it. >> roger stone was deposed today by the january 6th committee. he was planning to invoke the fifth amendment for much of his deposition. we'll find out more about whether or not he did that. it does pose the question. why wouldn't other witnesses such as mark meadows or steve bannon who both just refused to show up to testify, why not just show up and plead the fifth? >> right. that may be what they end up doing because they know perhaps that if they -- they don't want to perjure themselves under oath, right? that's what they are trying to do. they want to avoid having to lie or having to admit that they had a hand in trying to overthrow democracy and had a hand in allowing what happened on january 6th to happen. so we'll see what happened with roger stone. we'll see what happens with mark meadows. but these people really love this country, if they were true patriots, if they believed in all the conservative values they've been espousing for years, they would just go and tell the truth about what happened. >> s.e. >> daniela, thank you. it's starting to look a lot like a christmas of cancellations everywhere you go. and we've not even hit the so-called viral blizzard. plus, why a tiktok threat forced hundreds of schools to cancel class today. stay with us. ot. so take care of that heart with lipton. because sippin' on unsweetened lipton can help support a healthy heart. lipton. stop chuggin'. start sippin'. before discovering nexium 24hr to treat her frequent heartburn... claire could only imagine enjoying chocolate cake. now, she can have her cake and eat it too. nexium 24hr stops acid before it starts for all-day, all-night protection. can you imagine 24 hours without heartburn?

covid protocols. this is all in response to deaths, increasing in nearly half of u.s. states, up sharply in seven. that's an increase of 8% from just last week. >> i think we're really just about to experience a viral blizzard. if you look at what happened in south africa, in europe, in the next 3 to 8 weeks, we're going to see millions of americans will be infected with this virus. >> we are looking at a winter of severe illness and death for the unvaccinated. >> reporter: as with previous surges, the unvaccinated are filling hospitals as weary doctors warn they are exhausted and losing staff. >> the reality is you can't -- you can't just create humans in order to provide that care and staffing is a challenge everywhere. >> now the nfl announced three games this weekend would be

all of them are going to be postponed a few days because of the number of players being put on the covid-19 reserve list. >> i can wait a couple more days for the eagles. kyung lah, appreciate it. joining us to discuss, chief medical correspondent dr. sanjay gupta. sanjay, this is a damning new report from the committee revealing how the trump white house deliberately undermined the covid response because the administration put trump's re-election ahead of america's health and safety. that's their take. you have spoken to former trump health officials throughout this pandemic. when you hear this, when you see two years later cases still spiking, lines still forming, just to get tests, what stands out to you? >> well, you know, what stands out to me, reporting on this consistently and talking to these officials in the beginning there was a desire to downplay this, to say hey, maybe this isn't going to be as serious as we think, which i think a lot of people realize that was happening and there was a lot of wishful thinking. what is striking from this report and also some of the interviews i've done is that became increasingly strategic. the idea of saying, hey, people who have -- who don't have symptoms don't need to be tested despite the fact we knew much of if not most of the spread was coming from asymptomatic people. and then also just really curtailing the amount of time officials could speak about this. they were -- had to get permission. oftentimes couldn't got those permissions. it was really challenging. i asked dr. deborah birx about this for this documentary. take a look. >> were you being censored? >> clearly someone was blocking me from doing it. my understanding is i could not be national because the president might see it. >> that's sort of an example of what it translated to for people like dr. birx. but even dr. fauci who said they were ready to present a new plan in terms of how to progress with the pandemic. and around the same time, tweets were going out saying liberate michigan, liberate virginia. very much at odds with what the scientists were saying. >> president biden has offered a clear warning. if you're unvaccinated, you're looking at a winter of severe illness, maybe even death. what is this winter going to look like for those of white house are va-- of us who are vaccinated, even with the booster. >> you should feel pretty good if you are vaccinated. as you know, i think the hospitalizations end up being the truest metric of things. it's so tangible. are hospitals becoming overwhelmed or not? the vast majority, unvaccinated patients with covid in the hospital compared to the green line. what happens, jake, if these hospitals do start to get full, the tangible impact on people in society is that the hospitals may go in diversion. they may not have enough beds. harder to take care of trauma patients, harder to do elective operations. so that impacts everybody. so that's, even if you're vaccinated, that could have an impact on you. and also just look at omicron versus delta for a second. everyone says this is more contagious but i want to show you what that means based on some of the data out of the uk. what they found was that to get to 5,000 omicron cases, it took 20 days. for delta, which was super contagious, it took closer to 70 days. 75 days to get to that same number. so, you know, you get an idea of just how much more contagious. people are going to get exposed. people are going to test positive as a result of those exposures. even the vaccinated. that's going to interfere with -- there will be quarantines and all sorts of things that result from that. >> the cdc updated its guidance to allow kids exposed to covid to test rather than forcing them to stay home for a ten-day quarantine. do you agree with that? >> well, you know, at first i thought this was going to be tough to actually implement. are you sort of saying will testing in this sort of situation be effective enough? let me show you what they found. they looked at 31 school districts. 90 different schools. and they basically implemented this policy. and out of those students, i think they had 16 people who tested positive out of -- there you go, 1,035. they found out they saved over 8,000 sort of days of school as a result of this sort of plan. so it looks like it's working based on a couple of these studies coming out. so the cdc is showing enthuse for this. we'll see if it's something that's adopted more widely. >> you're back this weekend with the sixth installment of your series on medical marijuana called "weed." you investigated cannabis and autism. why that subject, and what did you find? >> well, there was a couple of reasons. we've been reporting on this for some time. we were reporting on the use of cannabis for refractory epilepsy, seizure disorders. researchers kept telling us in addition to the seizures children sometimes had these symptoms of autism which did sometimes also improve as a result of being treated with cannabis. 14 states now permit the use of cannabis for severe autism. we wanted to really look at where the data is on this. the trials that are happening in the united states, but also even earlier than the united states in israel. but also introduce you to families who have been dealing with this, jake. the thing that always strikes me about the cannabis as a medicine sort of story is that oftentimes it's the evolution of things. these kids have tried so many different therapies, including powerful psychotropic drugs that don't work for them and they evolve to can base. and sometimes, not always, but sometimes they get some really remarkable results. >> dr. sanjay gupta, thank you. you can watch "weed 6" marijuana and autism at 8:00 p.m. on sunday. >> progressives were promised it would get done if they just said yes to the bipartisan infrastructure deal but president biden just admitted it's not going to happen this year. chair

biden's christmas wish list is now his new year's resolution. acknowledging two major parts of his agenda are stalled in the u.s. senate. today president biden told graduates at south carolina state university, historically black college, that he'll keep up the fight to get voting rights passed. and in a statement yesterday biden said talks on his build back better plan are ongoing, acknowledging he'll miss his self-imposed christmas deadline. let's bring in jeremy diamond live at the white house. president biden did not get into the particulars of why these deals are not yet done but he did name check one of the known holdouts on build back better, democratic senator joe manchin of west virginia. >> that's right, jake. the president in that statement yesterday acknowledging that there will not be a deal on build back better in time for the new year. certainly not by christmas. the president saying that there will be days and weeks of conversations ahead, and in that same statement, he did name check senator joe manchin making clear the conversations with him are still ongoing, but that they have not yet yielded a deal. that was really one way of saying that they are still very, very far apart. that is that the divide between senator joe manchin on the one side and senate democrats and the president on the other side still remains very wide. and it's certainly not going to be bridged by the end of this year. that frustration was apparent among senate democrats this week who begin to talk about the frustration of dealing with senator manchin and the fact in a 50/50 senate, he is one of the main holdouts here on pushing this forward. now the president's concession here that this isn't getting done ultimately running into the reality of the fact that they are not only far apart but also that time was indeed running out. the senate is about to go into recess just hours from now as they are expected to wrap up some nominations here. and then this makes the very difficult task of guesting this done in 2022. it is certainly not a cliff. nothing magical happens. once the clock changes to 2022, but it does become more difficult the longer you go into that midterm year. >> jeremy diamond at the white house, thanks. let's bring in democratic congresswoman pramila jayapal. she chairs the congressional progressive caucus. congresswoman, thanks for joining us. president biden says his conversations with senator manchin are going to continue next week and that, quote, it takes time to finalize these agreements, prepare the legislative changes and finish all the parliamentary and procedural steps needed to enable a senate vote, unquote, but isn't this exactly what you and your fellow progressives feared that biden's infrastructure plan would become law and build back better would ultimately die because of people like senator manchin who has never been enthusiastic about it to begin with. >> yeah, jake, it's great to see you. look, this is what we feared. it's why we tied the two bills together to pass them through the house. and we did take the president's word that he would get 50 votes in the senate and the president called me yesterday. i do believe we will get there. i think he is still just as committed. and i don't think it's out of the question that we'll at least have an agreement by the 25th. part of the reason we didn't want to vote for the bill when it was just a framework is because when a framework gets translated into legislative text, there's a lot of things that happen. and we did add in the house some things that were not in the framework, and i think we did it because we thought they were important but i do think that there's still a negotiation going on about which of those things will survive that are beyond what the framework was that was agreed to. and so that is the conversation that the president is continuing to have with senator manchin and i think that, you know, i said when we passed it out of the house and in the days leading up to it that negotiating is a tricky business. there are a lot of swings. and i think that swings back and forth and we can't hang our everything on, you know, whatever one person happens to say on a particular day. i still think we're going to get it done, and i've been urging the president. i communicated this to him yesterday from the progressive caucus, that we are trusting his word. we does need to deliver on this because it is 85% of his agenda. it's what we're going to do to actually address rising costs across the country by lowering costs of child care, lowering costs of prescription drugs, insulin. paying 35 bucks for your insulin instead of hundreds of dollars. and so i believe we're going to get it done, and i think we should continue to push for an agreement on the legislative text, the changes will still have to be made. that may take longer. but on that legislative text before december 25th, and that's what i told the president. >> but a source told cnn that talks between biden and manchin over the bill are, quote, very far apart. have you seen any movement between these two parties in recent months? what makes you believe that they can actually come up with an agreement by christmas or a deal by next year? >> i'm not sure that that's accurate. i was going to say that in listening to the reports because, you know, the president and senator manchin agreed on a framework. it was months of negotiation because we held up the infrastructure bill. we were able to get that agreement moving. we got the framework that, as you remember, jake, was rolled out the day before the president went to -- or the day that the president went to europe for cop26. that is the framework that had the commitment, and i think that, you know, it's not -- i don't think it's accurate to say we're very far apart or that they're very far apart. i think there are some details that need to be worked out. i think there was a commitment that was made by senator manchin to the president about that framework. and i think now the question is, you know, what about making sure that this legislation is what that framework was, plus what of the things that have been agreed to beyond that can be incorporated. so i don't think we're very far apart. i just think this is the back and forth of negotiation. i think we're going to get it drngs and i think we are counting on the president to deliver on this. >> one major sticking point is the child tax credit. the plan now extends the child tax credit for one year. manchin believes the benefit will likely ultimately be extended beyond one year and that cost of that to extend it make it permanent even will hike up the bill's current price tag which manchin wants to keep at $1.75 trillion. i mean, he's not wrong, right? you do want this to be permanent. >> look, he is wrong on this. and even as i was trying to follow your logic, i was getting lost. not if your logic but the logic being made because, look, we score bills based on what the bills are. you can't score a bill based on a fictional cost being added without saying, well, there may be a fictional pay-for added as well. everything in this bill is paid for. the cbo scoring is it's deficit neutral for the first decade and for the second decade it cuts the deficit. we had to make choices to let some programs only go for a shorter period of time which means we'll have to try to extend them if we can. but at that point, we'd also then be able to say, and we have this pay-for. so it makes no sense to score a fictional bill and only increase the cost but not increase the revenue side of it. so the real score is this bill is deficit neutral and it reduces deficits for the second decade. >> democratic congresswoman pramila jayapal, thank you. if i don't see you, merry christmas, happy new year. hope you have a wonderful, wonderful holiday with your family. >> thank you, jake. to you as well. the former police

>> it did, jake. even now it still remains unclear what or who was behind this threat that authorities were able to confirm that was not credible but nonetheless certainly led to concerns from parents and even increased police presence. tiktok has been investigating since these threats began to circulate online. and so far, they posted an update on twitter basically saying what they have and have not been able to find. the platform writing they've exhaustively searched for content that promotes violence at schools today. but have still found nothing. what we find, they write, are videos discussing this rumor and warning others to stay safe. tiktok going on to write, local authorities, the fbi and dhs have confirmed there's no credible threats. we're working to remote alarmist threats that violate our policy. and they lay out that policy there. but in the end this is all coming amid growing calls for social media platforms like tiktok to be more proactive and to be more responsible in the way that it monitors its content to try to keep things like this from happening again. it did lead to some serious concerns for parents and students across the country. >> polo, authorities took this threat seriously. some school districts shut down today. what are officials saying about the reaction to this? >> yeah, if they didn't shut down, and it was one houston area school district i read about that we were able to confirm, they implemented a backpack ban. some increasing their police presence as well just to take no chances at all. what you hear from local law enforcement and just authorities across the country, there's a concern that even all of this noise on social media could provoke at least a lone individual to potentially carry out these kinds of attacks. not to mention the damage done stretching law enforcement out and also those concerns for staff, parents and those kids that were just trying to bring their fall semester to a close. >> polo sandoval, thank you. coming up, cnn goes inside the lab where they're trying to find out just how transmissible the omicron variant is. ♪ this... is the planning effect. this is how it feels to know you have a wealth plan that covers everything that's important to you. this is what it's like to have a dedicated fidelity advisor looking at your full financial picture. making sure you have the right balance of risk and reward. and helping you plan for future generations. this is "the planning effect" from fidelity. new projects means new project managers. you need to hire. i need indeed. indeed you do. when you sponsor a job, you immediately get your shortlist of quality candidates, whose resumes on indeed match your job criteria. visit indeed.com/hire and get started today. as a professional bull-rider i'm used to taking chances. but when it comes to my insurance i don't. i use liberty mutual, they customize your car insurance, so you only pay for what you need. wooo, yeaa, woooooo and, by switching you could even save 665 dollars. hey tex, can someone else get a turn?
