emphasize that no final decision on deployment has been made. we should be clear these are not u.s. forces going to ukraine to fight russia, but to bolster existing deployments among nato allies. white house deputy national security adviser jonathan finder told cnn last hour that all systems are go. >> the alliance will make decisions about force posture adjustments, but they're ready to go at a moment's notice when the alliance decides. and, you know, the important thing to point out, this is not an aggressive step by nato, this is a defensive step. >> the question is how will russia view this step? the latest step to reinforce security on nato's eastern flank comes after president biden held a video call with european leaders on monday. the president stressing there was unanimous resolve among allies on that call. on the ground in ukraine, cnn has learned that the u.s. marine corps has bolstered security at the u.s. embassy in kyiv. the move comes days after the state department ordered family members of embassy to leave the country. it also comes as the defense department warns that russia continues to add battalion tactical groups to the border with ukraine and neighboring belarus. we are covering all of the latest developments this morning, and we begin at the pentagon with cnn's barbara starr. barbara, as we said, at least 8500 u.s. troops now on heightened alert, in final decision as to when to deploy and if, but what type of forces are we talking about exactly? >> well, we're talking about the kinds of forces that are equipped and ready to move very quickly. the military has a number of units that specialize in that very issue, moving to contingencies overseas on just potentially hours' notice, if it comes to that. so what are we looking at? we're looking at potentially ground combat brigades, aviation, intelligence surveillance and reconnaissance, logistics, medical capability, support capability, the kinds of things that these countries on nato's eastern flank will be so interested in having the u.s. provide along with nato, to bolster them. and you're exactly right, of course. this is not about ukraine actually. it is about the defense of eastern europe, think the baltics, poland, romania. we don't know what countries yet. most of the u.s. troops are earmarked, we're told, for that nato response force, if the alliance makes the decision to activate that force. but there is actually still the possibility that some u.s. forces could go essentially unilaterally, bilaterally to other countries, who agree to accept that defensive help. the u.s. very much emphasizing this is a defensive measure, but also saying that the u.s. troops would be ready for any contingency. >> and important to note as barbara noted, these are not u.s. combat forces going to ukraine to fight russia, but to bolster existing deployments among nato allies. clarissa ward is in kyiv. ukrainian officials have not been shy about expressing dissatisfaction with some u.s. moves, they have not been happy as of yet with sanctions or when sanctions might be imposed on russia. what did the foreign minister tell you this morning? >> so we sat down with dmitry and he said he feels it is very important to project strength when you're dealing with president putin, that president putin really only responds to and respects strength and that's why ukraine really welcomes this decision to put these 8500 troops on heightened alert to potentially be deployed in eastern europe. he did say that there are areas where there are clear differences with the u.s. we mentioned the embassy personnel, the decision to withdraw their families, he said he thought that was premature, he admitted to being annoyed by it. there is was one interesting conversation we had in particular on the diplomatic process. we asked about what will happen if concessions are given by the u.s. to russia in order to try to facilitate some kind of diplomatic compromise that will ultimately impact ukraine, because ukraine does not have a seat at this negotiating table. take a listen to what he told me. >> if anyone makes a concession on ukraine, behind ukraine's back, first we will not accept that. we will not be in a position of a a country that says here is the instruction of the big power, and follow it. no. we paid a lot, including 15,000 lives of our citizens to secure the right to decide our own future, our own destiny and we will not allow anyone to impose any concessions on us. >> reporter: he went on to say that the u.s. has already made concessions in its dealings with russia in previous diplomatic negotiations and he said if anyone comes to ukraine demanding that ukraine make further concessions, he will literally in his words instruct the protocol guide to escort or accompany him back to the airport. the ukrainians not mincing words here, jim, being very clear about their intention to take a position of strength here, even though they're not at that negotiating table, they're also not going to be pushed around and told what concessions they will have to make. >> really defiant message there from the foreign minister and you're right to note the president asked repeatedly for a three-way meeting with president biden and president putin and that did not happen. let's turn to the white house. jeremy diamond is there. jeremy, the biden administration will hold, we hear, two classified briefings today for could congressional staff on this ukraine crisis. what more do we know about the information that would be presented? >> reporter: that's right, bianna, these briefings are going to be for the staff the house and senate leadership and committees, and they're going to be classified briefings and it comes at a critical time, not only as the u.s. has put on alert the 8500 troops, but as they're also putting the finishing touches on these sanctions that russia that would be imposed on russia should russia move to invade ukraine in the coming days and weeks. these are not the first briefings that the white house has given to house and senate staff or membership, it is the latest in a series of dozens of engagement the white house says that they have had with congress since december. but, again, the possibility of troops being deployed now to bolster nato allies in eastern europe will hang heavy over this meeting. interestingly we heard the white house deputy national security adviser john finer and he made very clear that the deployment of these 8500 troops would come with the consultation and decision being made by the nato alliance at large, not necessarily a unilateral u.s. troop movement, though, of course, as barbara noted there is still that possibility of additional separate forces being sent unilaterally by the united states to bolster the defenses. we know the president himself has also had engagements including with the heads of the foreign relations committees. he has spoken with them himself. as for the president himself, we're not expected to see him today. yesterday, questions were posed to him on this question of ukraine and russia, but he is staying tight-lipidped now at ts moment of tension and uncertainty. >> thanks so much to all of you. for more on this, let's speak to cnn military analyst retired general wesley clark, the former nato supreme allied commander. general clark, good to have you on again this morning. >> thank you, jim. >> to date, u.s. nato moves have been if moves, in other words, preparations to further deploy these troops, preparations for economic sanctions. they're not preemptive. you've heard criticism from ukrainian officials saying sanction now, make the moves now to deter. and i wonder in your view, is it a mistake to wait, does it give putin the initiative, right, by waiting for further action before the u.s. and nato respond? >> well, i think it is important to push for more active deterrence. but the governing principle is alliance unity is the most important thing of all. there is a lot of work going on behind the scenes, jim, to bring -- online, germany and france are meeting today to talk about the situation. look, we're not going to intervene militarily in ukraine. the president has said that. our allies know that. but what really will deter putin is nato resolve. this means we're all in this together. we have to bring consensus among our nato partners and go step by step into this. when i was a commander in 1999, we had the same problem, moving against milosevic, it took step by step work to bring the europeans on board, we knew ethnic cleansing was happening then in kosovo, but you couldn't simply snap your fingers. if you want an alliance, an alliance of democracies, you to respect the processes in each of these countries. >> so, general, to that point, we are expecting to see a written response from both the united states and nato, to russia's demands about the future of both ukraine and nato expansion. what should those responses look like? >> well, they're going to say, diplomacy is still open. we're happy to talk about things like missile positioning. we want to talk about strategic nuclear in a u.s./russia bilateral, perhaps, but we're not going to say that nato won't admit new members. we're not going to say that nato will roll back its task forces that are deployed into the former countries of the warsaw pact or the baltic states. and so it is going to be a mixed message back to moscow. this is all part of the game that mr. putin's playing. we don't know whether he's going to actually launch his military or not. if he can get what he wants, without putting a military in, that's what he wants. and so he ratchets up the pressure, he goes behind the scenes to different countries to see is there any daylight there, can i shake up a government? he's going to run demonstrations in ukraine against mr. zelensky, he's going to try to create civil disturbances there. it is all part of the game. it is no different than in football when you're the quarterback, might give a hut two and try to draw the other team offsides before the play starts, mr. putin wants to draw us offsides, he wants to shatter nato or shatter ukraine before he ever moves. and then maybe he gets his own government in ukraine, he thinks. maybe he can control it that way with just putting a few -- in. but he's building up the force, and there is a number of us who feel that actually what he probably wants to do is use that force, show it off, ukraine is the punching bag to intimidate the west. he's got the military. it is going to be tough. >> general clark, a lot of the focus has been on a clear cut ground invasion, that is rolling tanks like those pictures we just played on the air across the border. but there are a whole host of options short of that or prior to that, right, massive cyberattack, they used that playbook before against estonia, air strikes, further reinforcing the forces they already support in eastern ukraine, the so-called separatists there. do you believe it is a mistake to imagine the only outcome is a full scale invasion? are there options short of that that putin might use and consider in advance? >> well, he could use options short of that, but you don't know that he won't then make that just phase one and move to a phase two. so when this unfolds, you don't know what the end result might be. he's continuing to reinforce forces into belarus, so if you were in the baltic states, you would be looking at these forces coming in. if you were in lithuania, let's say, or poland, and you would be saying this is a concern. so you don't know what he's going to do and this is part of putin's strategy. he's a wiley strategist. so you have to keep in mind that as he builds up the forces with the overpowering air capabilities, his air defense and long range missile capacity, he does have the capacity to knock out ukraine's, most of ukraine's high tech defense. he'll have to fight people on the ground, but the ground is frozen there, he can move the tanks through the swamps north of kyiv, he could have forces outside kyiv and if they weren't actively resisted in a day. >> yeah, look, another option for him would be to weaponize energy, which he's done in the past as well. raises a big question as to why nato in european countries there are not more energy independent. this is something you raised in the past as well. we'll have to leave the conversation there. we'll continue to cover it and would love to have you join us again in the future. general wesley clark, thank you. >> thank you very much. well, up next, the partying prime minister, details emerging this morning of yet another party that boris johnson attended while he was enforcing a covid lockdown for the rest of the country. and now police are investigating. >> police investigating. that's quite a development. florida shuts down all of its monoclonal antibody treatment sites in response to new guidance from the fda. florida was leaning on those for some over vaccines. and later, the attorney who helped craft former president trump's boeigus theory to overtn the election may have thousands of emails released to the january 6th committee. details of what could be inside of them. hello, for the last few years, i've been a little obsessed with chasing the big idaho potato truck. but it's not like that's my only interest. i also love cooking with heart-healthy, idaho potatoes. always look for the grown in idaho seal. my plaque psoriasis... ...the itching... the burning. the stinging. my skin was no longer mine. my psoriatic arthritis, made my joints stiff, swollen... painful. emerge tremfyant®. with tremfya®, adults with moderate to severe plaque psoriasis... ...can uncover clearer skin and improve symptoms at 16 weeks. tremfya® is the only medication of its kind also approved for adults with active psoriatic arthritis. serious allergic reactions may occur. tremfya® may increase your risk of infections and lower your ability to fight them. tell your doctor if you have an infection or symptoms or if you had a vaccine or plan to. emerge tremfyant® with tremfya®... ask you doctor about tremfya® today. uk prime minister boris johnson says he welcomes the london metropolitan police's decision to investigate several events that may have violated covid restrictions at number ten downing street. itv is reporting two gathers were held at downing street in june 2020 during lockdown. those gatherings to celebrate boris johnson's birthday. >> and we're learning more this morning that the new police investigation could delay the findings of an internal government probe. cnn international correspondent scott mclean is live in london this morning. scott, i don't know, are we at number seven or eight? how many parties have we uncovered at this point? and what is the prime minister saying now? >> reporter: so it is just the drip, drip, drip of one allegation after another, things are certainly getting complicated, the civil service report was expected to be released this week into the investigation into all of these parties, but now things have gotten a lot more complicated since things have been turned over to the london metropolitan police. and for weeks they have insisted that it is their policy not to go back and retroactively investigate, but now it seems abundantly clear that there san exception to be made in the name of public interest. and what is really telling here is the criteria that the chief of police used to justify this investigation. two of them include clearly being no reasonable defense, and evidence that people knew that what they were doing was against the law. hard to claim ignorance when you're the ones making the laws. the prime minister is trying to shrug this all off, change the channel, kick the can down the road, whatever you want to say, but headlines like this certainly do not help. this is one of the tabloids, the mirror, there were severe restrictions on social gatherings including a ban on gatherings indoors. and this one, you can't have your birthday cake and eat it too. they have gotten creative in how to defend themselves. they tried to explain all of this away this morning. listen. >> he didn't organize a party. someone presented a cake to him. >> and singing. >> happy birthday, mr. prime minister, happy birthday, to you. >> it was his birthday. these are people he worked with all the time. as i said, i don't seek to defend it. this is for sue gray to decide whether this is appropriate. >> sue gray is leading the investigation. it is important to keep in mind that legal jeopardy is not boris johnson's big problem right now. if this police investigation were to find that he broke the law, chances are the punishment would be a fine, perhaps a series of fines. the bigger problem for the prime minister right now is the fact that it would say unequivocally that the prime minister did break his own laws at the time, which were taken very seriously by the authorities and that might prompt a lot of his own mps to vote for a confidence challenge to his own leadership and soon we may have a new prime minister. jim, bianna? >> yeah to have a police investigating truly remarkable the prime minister's own party. scott mclean, thanks so much. new this morning on covid, pfizer and byiontech announced n omicron-specific vaccine. >> this could be a major development. elizabeth cohen joins us now. several cities have already passed the omicron peak. so as welcome as this news may be, will it make a significant difference at this point? >> you know, it is interesting, it is unclear what kind of difference an omicron specific vaccine would make, as you said, by the time this comes out, many of the country will have passed the omicron wave because the waves come and go, they're very intense, but they come and go very quickly. so the question is are we fearing omicron for next year, the year after? is that what it is for, and how us useful would it be in that situation? pfizer says they're already making the vaccine and they're testing it in a clinical trial. let's take a look at what they're doing in this clinical trial. they say they're going to have up to 1420 participants and they'll divide them up into groups. so group one has already had two doses of pfizer. just in their regular life, not as part of the trial. and then pfizer in the trial will add one or two omicron doses to see what happens. a second group, they already had three doses. so two doses, plus the booster. and the trial, they'll give them one more regular dose or an omicron dose, and then group three is a group that is completely unvaccinated, never got vaccinated during the pandemic and they'll be given three regular omicron doses and then they will see how these folks do, do they get sick with omicron. there is a lot of different groups here, a lot to keep track of, it will be interesting to see what is most effective and then if you put this in terms of the real world, is it even necessary? how useful would this be? >> yeah, because booster folks of the current vaccines have done really well against omicron. i want to talk to you about something else. one way that the vaccine hesitant have gotten around this is talk of monoclonal antibody treatments. heard politicians back that up, including florida, the governor saying we're going to have a lot of that if you don't want the vaccine. notable the state of florida shutting down its antibody treatment centers. why? and how significant? >> you know, it is interesting because the state of florida put out this press release, but they missed the most important thing, they didn't put in there what monoclonal treatments were being used in these clinics. there is some treatments that are worth not using, because they don't work particularly well against omicron. and then there are others that actually are useful during the omicron wave. so let's take a look at sort of what the deal is right now with monoclonal antibodies and omicron. so, if we take a look at ones that are not recommended against omicron, those are ones made by regeneron and eli lilly. they worked well during delta, but didn't work well against omicron. the nih said basically don't use them. so if florida is getting rid of those two, that actually makes sense because florida, like most of the country, is 99% omicron. so why use those two? however, there are two that are useful. and one of them is called sitrovamab, that has been useful, the ever one is evusheld, it is intended for people who are immunocompromised for many people in that group, the vaccines haven't worked very well. florida made this big fanfare about, oh, the federal -- because of what the federal government has done, we're going to shut down these clinics. that's probably smart that you shut down the clinics. what about the two that do work, what are you doing about those? florida has doses of those, what are they doing with them? >> if there are enough supply of just those two treatments right at this point to be effective. >> right. there aren't. >> exactly. >> elizabeth cohen, thank you. thank you as always. state supreme court judge has struck down new york's state wide mask mandate. the judge ruling the order is unenforceable because the governor did not have the authority to issue it in the first place. >> most people still wear the masks. jean casarez joins us from new york. jean, notable comments from the judge here. what were the key issues? >> this came down late yesterday. it was a bombshell last night. the judge is ruling on a procedural level, not on the merits of the case. and he's saying that it is unenforceable because when it was made by the governor that all of the citizens of the state of new york must wear a mask in the prevention of covid-19, new york was not under the state of emergency. and because of that, the proper way to do it would have been to go to the legislature, elected by the people, and they would make the decision, and because that wasn't done, it can't be enforced. it is true that it was in november that the new york state health commissioner actually created the regulation that everyone had to wear these masks. the judge said, the new york supreme court in nassau county, he says, to be clear in his ruling, the court does not intend this decision in any way to question or others with opine on the efficacy, need or requirement of masks as a means or tool in dealing with the covid-19 virus. the court decides only the issues of whether the subject rule was properly enacted, and if so, whether the same can be enforced. now, we did learn that the new york state department of education says they're aware of this, that they understand that the department of health is going to go to court immediately today to appeal this ruling, and therefore to get conceivably a stay so that everything will stay status quo. but in the meantime, we're hearing that at least six districts, parents have been told that masks are optional today for their children. but that it most likely will be changed if this stay is put into place. but obviously it sets a precedent and it is the governmental balance of powers and will be very interesting to see how this turns out in an appellate court. >> created quite a frenzy. jean casarez, thank you. still ahead, the new york city mayor responds to criticism of his blueprint to combat gun violence. why he says the plain clothes police unit will be different than before. and we're moments away from the opening bell on wall street. u.s. futures are down to start the day after a wild start to the week monday, where markets saw a huge sell-off and epic reversal before the closing bell. the problem, well, ukraine tensions, disappointing corporate earnings, and persistent inflation concerns. and fighting inflation means a new era of higher interest rates. we'll talk more about that market anxiety later this hour. power e*trade gives you an award-winning mobile app with powerful, easy-to-use tools, and interactive charts to give you an edge, 24/7 support when you need it the most. plus, zero-dollar commissions for online u.s. listed stocks.

and when eric adams is calling for is for further reforms now where they can give more discretion to judges to keep people who are dangerous behind bars and that is one of the key things in this proposal. yeah, he's also calling to bring back these plain clothes cops, calling them neighborhood safety teams, giving them a new name. they are going to be in plain clothes, but they will have something on them, whether it is a field jacket, some kind of thing that is going to identify them as police officers. a big change certainly from way back when we had the anti-crime units and the street crime units. adams this morning was defending that move, take a listen. >> i know how unfair and abusive that unit was because i testified in federal court. and the judge's ruling acknowledged my testimony, new york city versus floyd, to rule against the behaviors and practices of the police department. using that knowledge, we want to reinstitute an anti-gun unit where police officers will have a modified version of police uniform apparel, they are going to be better trained, we're going to use technologies with cameras to video every interaction and i'm going to make sure the right officers are assigned there. >> and, jim and bianna, the big focus in all of this right now is gun violence. we have seen this surge in gun violence. obviously two officers being brutally attacked with -- by that man with that weapon, that is something that adams is focusing on. he also knows this is something that police officers in the city want to hear. they like these anti-crime units these neighborhood safety teams because it gives them the tools to fight crime. but what adams also realizes is that he needs the district attorneys, he needs legislators to make changes. all of this is something that police officers want to hear, that's why we heard from one of the unions already saying, you any what, this is a step in the right direction, supporting the mayor's move in all of this. and in the end, i think, jim, what is going on here is that adams knows that if he doesn't have the police officers working, if they're not willing to do the work, nothing changes. and in the end, you need the d.a. and the legislators also to support the officers. so there is a lot going on here. let's see how this all unfolds in the weeks and months to come. >> two things you hear from cops a lot, concerns about guns and you hear that oftentimes they'll arrest someone and that person will be back on the streets before they even complete the paper work, and that's the issue it seems adams is trying to begin to address here. >> and, look, he argues he has a mandate to do that. it was interesting to hear him over the weekend tell new york police officers specifically that new yorkers want you here, right, to instill that support that as you said, shimon, they feel they don't necessarily have at this point. shimon, always great to have you on. thank you. here in washington, the january 6th committee could soon learn more about the expansive efforts to overturn the 2020 election on behalf of the former president trump. a federal judge has ordered conservative lawyer john eastman to respond to a subpoena for his emails from his former employer. >> yeah. third party will then sift through as many as 19,000 emails to determine what should stay secret and what should be turned over. cnn's whitney wild joins us from washington. whitney, what are lawmakers hoping to learn from these many thousands of emails potentially? >> well, they're hoping to learn the granular details of what john eastman was doing in the days leading up to january 6th and who he was doing it for. ultimately the question is was he working on his own behalf or was he working on behalf of the former president? and during this hearing, this very critical hearing yesterday, john eastman's lawyers said over and over and over that these efforts that he was making were on behalf of former president donald trump. that is critical because this is information that the house select committee was not able to get out of john eastman when he went in for a deposition and pleaded the fifth to more than 100 questions, so, the hearing yesterday turned up substantive information that the house select committee wants to know and further opened the door to more information that the house select committee thinks is critical to understanding what was going on within the trump camp, the intentions, the specific planning that went in to try to overturn this election. just one example of that was when john eastman met with more than 300 state legislators to try to get them to stop this egregious conduct was the quote from that select committee subpoena to john eastman. there were many instances along the timeline. in which john eastman was trying to, you know, use what he thought at the time were legal avenues to try to overturn the election and house select committee wants to drill down on what the plan was and who directed it. back to you. >> a lot of court losses for the folks trying to not cooperate with the committees. so the judge is ruling in favor. whitney wild, thanks so much. there are only ten days to go until the beijing winter olympics begin. already covid cases popping unside the bubble. how the city is trying to respond coming up. this is the new world of work. each day looks different than the last. but whatever work becomes, the servicenow platform will make it just, flow. whether it's finding new ways to help you serve your customers, orchestrating a safe return to the office... wait. an office?
