♪♪ >> brennan: good morning. welcome to "face the nation." we have been told repeatedly that the next few weeks in ukraine will be crucial, so the urgency for more support for the country is no surprise. but the official announcement of a top-secret trip on part of the biden administration officials as we go on the air has not been confirmed by the u.s. but word is out. cbs news foreign correspondent charlie d'agata is in ukraine. >> reporter: good morning, margaret. it came as a surprise, to say the least, when president zelenskyy said that the u.s. secretary of defense would be arriving here today. saying it is no big secret. what tops the agenda: more weapons and fast.

in a marathon press conference held deep underground in a subway station, pausing at times for passing trains, zelenskyy struck a defiant yet thankful tone.[speaking forn language] >> reporter: let me stress, he said, all of the signals, steps, terms and amounts regarding u.s. weapons, all of this has improved, and for that i am grateful. it may be too late to save mariupol. ukrainian officials say russian launched airstrikes today on the besieged steel mill, sheltering soldiers and civilians. this video of families who have been hunkering down in bunkers for months was reportedly taken three days ago and released by the azoff battalion. it cannot be independently verified. president zelenskyy warned russia against the slaughter of remaining resistance fighters. if our men are killed in mariupol, he said, ukraine

will withdraw from any negotiation process. to the west, at least six cruise missiles landed in the black seaport sea of odessa. a strike on an apartment building killed eight people, including a mother and her 3 month old baby. missiles destroyed a facility holding weapons supplied by the u.s. and europe. they opened fire in the donbas region in eastern ukraine. despite these forces making some territorial gains along the 300-mile front line, ukrainian troops had the worst of it at a significant cost to the kremlin, according to british military intelligence. russian television broadcast live pictures of president putin attending an easter orthodox midnight mass. with the war he started raging on and the deaths of innocent civilians rising by the hour.

president zelenskyy said he is open to a direct meeting with president putin in order to end the war. in his easter address, he said, our souls are filled with fierce hatred for the invaders and all they've done. don't let that rage destroy us from within. margaret? >> brennan: thank you, charlie. we turn now to cbs news national security correspondent david martin. good morning. good to have you here, david. president zelenskyy in that press conference said weapons transfers have picked up in their pace from the united states, but he expects secretaries austin and blinken to arrive with something more for him. do you know what that is? >> well, weapons are going into ukraine today. i asked and was told there are no weapons on the particular train taking austin and blinken into ukraine. but there is clearly this race on to arm the ukrainians in time for

this coming battle. and the u.s. is shipping 90 of these 155-millimeter hhowitzers into ukraine. the u.s. is asking all sorts of countries who have that smaller caliber to provide it to the ukrainians. but these countries are not like the u.s., with these vast arsenals. when you ask them to give up their artillery, that is a big ask. >> brennan: uh-huh. >> reporter: but the race to arm the ukrainians with heavy artillery is probably going to decide the outcome of this coming battle in the east. and, of course, it looks like the coming battle in the east is going to decide the outcome of the war. so high stakes. >> brennan: and time seems to be of the essence

there. when it comes to what the united states has admitted it is transferring to the ukrainians, the types of weapons continue to change. are they still parsing what will provoke putin? are they still sort of saying there are things we cannot do? >> reporter: they certainly give every weapons system a clear scrub for will this cross his red line? the problem is nobody knows what his red line is. >> brennan: what that is. >> reporter: the russians sent this diplomatic note warning: don't send sensitive weapons because they will produce unpredictable consequences. who knows what they consider a sensitive weapon. probably not an artillery piece. but on that list of weapons provided last week, there was something called the phoenix ghost, tactical unmanned aerial systems. and i'm reading it off a list here because last week was the first time i

had ever heard of this thing. it is a classified program. we can't show a picture of it because there is no picture. but this is a comcasi drone, which finds one, and dives on the target to kill it. the u.s. has already given ukrainians about 700 smaller switch blade com comkazzi drones. will these be the weapons that cross putin's red line? who knows, but there is a dangerous dynamic going on here. the worst putin does, the more dangerous he gets. >> brennan: if he gets backed into a corner, as you have said, the question is: what does he then do? the u.k. has said the russians haven't really fully reorganized and resupplied. do the ukrainians have an advantage at this moment?

>> reporter: well, they certainly have a fighting chance. just the battlefield rule of thumb is the attacker needs a three to one advantage over the defender, and russia tries for a seven to one advantage, and they just don't have those kinds of numbers. beyond that, we have been talking for weeks about all of the shortcomings of the russian military: poor morale, poor command and control, poor logistics. those are not the kind of problems you solve in a few weeks. an american defense secretary once said: you go to war with the army you have. and the war that russia is going to go with in eastern ukraine is essentially the army that went to war in northern ukraine, and which failed to take kyiv. just to give you one example, they're trying to encircle the ukrainian army. >> brennan: right. >> reporter: to do that, some units have to travel 100 miles in order to get

in the rear of the ukrainian army. >> brennan: wow. >> reporter: in the offensive against kyiv, they overran their supply lines at 60 miles. >> brennan: david martin, great analysis. thank you. president biden met with ukraine's prime minister, denys shmyhal, here in washington. we sat down with the prime minister just before he returned to ukraine and began our conversation with the situation in mariupol. >> mariupol is now surrounded by russian army. some thousands of our soldiers, some thousands of civilians, together with them, it is mostly women and children, are hiding in the basements of this enterprise. soldiers are protecting the civilians, but russian soldiers is many times more than eye soldier our soldi.

now we have heard that russians began bombarding this enterprise, these sheshelters where our soldiers and civilians are saving from the bombs. it is terrible war crimes on the mariupol territory. >> brennan: there have been satellite images of mass graves around the city. your government has said mariupol might be a red line. and because of the atrocities, diplomacy may not be possible. are we at that point? has that line been crossed? >> mariupol is like symbol of brave ukrainian soldiers and civilians who for two months protect their city from russian invasion, from russian atrocities. so this is like the symbol for the world. they think it will be the red line for all civilized world, not only for ukrainian people. so we will protect our

country. we will protect our cities. and mariupol will stay to the end because of our soldiers, who say we will stay here and protect our city until then. >> brennan: i heard you say that it might be the worst catastrophe of the century. so do you believe, after doing something like that, that russia can negotiate in good faith? >> russia done many atrocities and many war crimes in ukraine. but we understand that this terrible war could be finished only on the table of negotiations. with presence of our partners of world leaders, of stabilized countries, but we should sign some papers about finishing this war. >> brennan: president biden says he will go to congress next week and ask for more money to provide weapons to ukraine. the last time that

happened, it took three weeks for congress to sign off on funds. do you have three weeks to wait? >> we count every minute, every hour, not every week or month because every minute and every hour soldiers, civilians, children, women are dying. because of this, we need faster decisions. but united states, europe union, civilized world make many faster decisions, and we so much grateful for this. we need more support. >> brennan: what specifically is it, is it medical supplies you need most? is it heavy weapons? is it just cash? >> we need weapons and medical support. but many countries support us because they take our injured soldiers. the cash in the sense of our budget is very important for social and humanitarian responsibilities of our

state to our people. >> brennan: and that's $4 billion to $5 billion a month ukraine needs? >> yes. >> brennan: did you get pledges for that here in washington? >> yes. we had many negotiations with g-20 countries, with i.m.f., world bank, so all of them approved this amount. but now, after liberation of some territories of ukraine, we need also support for finances and technologies for activities because more than 120,000 square miles are under under mining and bombs. some of the families going back to their house, opening their washing machines and refrigerators, is mining by russians. >> brennan: the u.n. secretary-general says he

is flying to moscow next week to meet with vladimir putin. do you think this is any kind of diplomatic breakthrough? >> i'm not sure. so many leaders of countries of civilized world, international organizations, tried to have this negotiation, but i think the russian federation and putin are not interested in these negotiations. intted in homicide ukrainians. they're interested in the migration crisis in the world. they are interested in the food crisis and energy crisis. i'm not sure they are capable to hold these negotiations in the proper way. >> brennan: here in washington, did you receive promises of more military training for ukrainian soldiers? >> we have support from our partners for military training right now. so we are training.

we study new technologies for our soldiers and our army. so everything is on its way. >> brennan: everything is on its way? >> absolutely. >> brennan: do you believe the u.s. wants ukraine to fight to a stalemate or to actually defeat vladimir putin, to actually win? >> i personally think that it is impossible to win the war, win the battle, with nuclear state. we may protect democracy in europe, on our continent, in the world, but i think that this war should be finished when we clean our territories from russian occupants. >> brennan: are you saying that a full withdrawal of russian troops is the only way to end the war? >> i think yes. if russians will leave territory of ukraine, if they will have guarantees

of safety for our country from our partners, if we will have possibility to recover our country using russia's frozen assets -- >> brennan: there is a proposal in congress to seize some of those frozen russian accounts and use them to repay damage -- to pay for damage in ukraine. did you get guarantees from the u.s. that they're looking at doing that? >> we have these negotiations with the united states, with all of our partners. this is very important international issue and task and goal, to find solutions how to take these frozen assets and finance the recover of ukraine in this case. and for future, it should be like standard. if some country should make aggression against another democratic country, it should pay for

this. >> brennan: so the $600 billion you said it would take to build ukraine, you think it can come from the yachts of oligarchs and banks -- >> absolutely, for a minimum. for now we count all of these damages and destroying infrastructure, destroying residential buildings, houses of the people, or the energy infrastructure, enterprises infrastructure, loading the g.d.p. for our country for many years because they destroyed part of our economy, so all of this should be paid by russia, absolutely. >> brennan: mr. prime minister, thank you for your time today. >> thank you so much. >> brennan: our full interview can be seen on our website at facethenation.com. we'll be back in one miebt one-minute to talk do dr. scott gottlieb. so stay with us.

digital tools so impressive, you just can't stop. what would you like the power to do? >> brennan: there was a lot of confusion last week

over masks, mandates, and vaccines for the very youngest. our mark strassmann has more from atlanta. >> no longer enforce the federal mandate requiring masks at all u.s. airports. >> reporter: with that mid-flight announcement, the masks came off. even passengers stuck in the middle seats applauded. >> i would say hallelujah. >> reporter: a florida federal judge, appointed by former president t masks unl. t administration appealed. millions of americans willio non >> reporter: bre are, still, and local guidelines prevail. los angeles county and new york city still require masks in airports and for

all mass transit. >> i just wish we got a clear answer on what we're going to do with this whole mask mandate. it just seems confusing. >> reporter: confused and alarm, immunocompromised americans, and the parents surrounded by ever fewer people wearing mavericks. no masks for 18 million american kids under five. they criticized the f.d.a.'s lack of action and urgency on a vaccine for young children that would give parents more peace of mind and help put the pandemic behind us. pfizer is working on a vaccine for young kids, and moderna could seek f..a. authorization in the next week. and for frustrated parents, both options could become available some time this summer. margaret? >> brennan: we go now to former f.d.a. commissioner dr. scott gottlieb who

joins us from westport, connecticut. good morning to you, doctor. >> doctor: good morning. >> brennan: i want to get to kids in a moment. i've got a lot i want to ask you about there, but let's start on the masks. put the legal argument aside, as a medical professional, when you get on a plane, are you still going to put a mask on? >> doctor: i wear a mask when i get on a plane while i'm boarding and while i'm getting off the plane. i think those are the two points where you're in a congregate setting where there is poor air circulation. those are the risky points in you're journey. when you're up in the air, 10,000 feet, there is pretty good air filtration on a plane, so i take my mask off while we're flying. that's been my practice since this mandate got lifted, and that's probably what mask, you mean an'l il n-95? >> doctor: yeah, look, i wear a kn-95 mask.

if you're wearing a poorer quality mask, a cloth mask, you're probably deriving a lot less protection than what you perceive. omicron is preyeding spreading through airborne transmission, so if you want to protect yourself from this pathogen, you need to wear a well-fitted, higher-, higherhigher-quality mask. >> brennan: we're still in a public health emergency. are we yet at an endemic phase of this? >> doctor: no. i think this year is really a transition year. i think this is going to be the year when this becomes more of an endemic illness. it will not be a defined point in time when that happens. but what is going to happen this is going to settle into more of a seasonal pattern. i expect prevalence levels to start to decline. we may be peaking right now, if you look at the waste water data through the summer.

then we're going to see it reim merge in the fall. the question is what reimmergence? is it a new strain of omicron? >> brennan: and fall makes kids' vaccines even more timely. stay with us. we're going to take this break and come back and finish our conversation with dr. scott gottlieb. dude, you should really check in with your team on ringcentral. i was thinking like... oh hi, caesar. we were just talking about you. ha ha ha. yeah, you should probably get out of here. not good. ♪ ♪ ♪ ringcentral ♪ thanks for coming. now when it comes to a financial plan this broker is your man. let's open your binders to page 188... uh carl, are there different planning options in here? options? plans we can build on our own, or with help from a financial consultant? like schwab does. uhhh...
