this mask? "it feels like going back in time," this woman told us, adding "it's like living on the stage. it's marvelous." their stage on this sunny sunday last february was saint mark square. they told us dressing up made them feel 100% venetian. it's a traditional historic venetian mask, this man told us. and hers, for example, he added, is the more etta. if you long at lon gi's paintings, you'll see these masks. indeed, pietro lon gi's work reveals how face coverings were a focal point of venetian life in the 1700s, not so different from davide bell oh anyway's years in the 1980s. >> my childhood memories are full of masks for sure. >> full of masks. belloni's parents were mask

makers and now through their family company, he's carrying on this craft. >> here in venice, it was a tradition, common costume of wearing masks not only during carnival but for at least six months a year. ant id not to be recognized. so people used to go around the city to public places, cafe, market squares, and so on wearing masks. >> what time period are we talking about? >> we are talking about for sure about the 1600s and 1700s, but we have some documtst aut masksm the middle age. >> reporter: masks allowed the mixing of classes, removing divisions in the strict hierarchy of venetian society. >> wearing a mask was a social equalizer in a sense. >> a social equalizer? >> yeah, a social equalizer. >> this is which one? >> this is the boata. >> reporter: in their shop, he showed us the boato costume of which the volto mask places a

>> and so for 200 years basically, this tradition was almost forgotten. >> reporter: until the 1970s when artisans including carlos braseco got to work. masks accompanied venetian culture practically from its origin, bra sesco told us, and we are trying to recover some of this tradition. we met as he was transporting a giant bulb and pigs to be used in a carnival parade, noting -- [ speaking non-english ] "in venice, everything is more difficult." the animals represent a carnival time gift the venetian republic demanded from a defeated army hundreds of years ago. bra sesco is keeping alive both the story and tradition. each year, the parade floats down the grand canal. the only mask mandate here is

tonight, cbs news goes in depth in part two of our series on americans being exposed to chemicals in our food and what's being done about it. plus, how former president jimmy carter's hometown of plains, georgia, celebrates his life every day of the year. but first, president biden, in a remarkable speech, promising the united states' unwavering support for ukraine in a message to the world from the royal castle gardens in warsaw, poland. the president marked one year since russia's invasion with a clear message to vladimir putin, saying nato has never been more united, democracies around the world are stronger than ever, and vowing that russia will never win in ukraine. in his state of the nation address, putin falsely tried to blame the west for the war. it was a 100-minute speech, and he also suspended moscow's participation in the last remaining nuclear arms treaty with the united states. cbs's ed o'keefe is traveling

with the president and will start us off tonight from warsaw. good evening, ed. >> reporter: good evening, norah. white house officials insist the president's speech wasn't designed to be a response to vladimir putin because it had been in the works for several weeks. but the dueling appearances led to a global tit for tat. the russian leader accused western nations of wanting to strike his country. the american president denied that and defended ukraine's right to exist. president biden in warsaw, president putin in moscow with dueling messages on the eve of the first year of war in ukraine. mr. biden recalled his high-stakes trip to its capital. >> one year ago, the world was bracing for the fall of kyiv. well, i've just come from a visit to kyiv, and i can report kyiv stands strong. [ cheers and applause ] kyiv stands proud. it stands tall. and most important, it stands free. >> reporter: and he sought to shame putin, accusing him and the russian military of

committing atrocities. >> they've committed depravities, crimes against humanity, without shame or compunction. they've targeted civilians with death and destruction, used rape as a weapon of war. >> reporter: thousands of polish citizens, ukrainian refugees, and american diplomats and aid workers gathered to see the president, the centerpiece of a stage featuring smoke machines and resembling a rock concert. hours earlier, putin's national address was delivered to a roomful of loyalists. he claimed russia isn't fighting the ukrainian people but that they've become hostage to western masters and said the west is responsible for fueling the ukrainian conflict. putin also announced he's suspending participation in the last remaining nuclear arms reduction treaty with the u.s. national security spokesman john kirby called that announcement unfortunate and irresponsible. >> at a time like this, you want to make sure that you can at least have some arms control in place. >> reporter: since president biden took office, the u.s. has

committed more than $30 billion in military assistance to ukraine, including grenade launchers and small arms, anti-tank weapons, shoulder-fired missiles, armed drones, body armor, and helmets. there's also been $1.4 billion in humanitarian assistance. but on the streets of warsaw today, the president saw signs reminding him many ukrainians want much more. president biden has so far rejected calls to send military jets to ukraine fearing it could spark a third world war. tomorrow he meets with leaders of eastern european countries that border russia to reiterate u.s. support for nato's eastern flank. norah. >> ed o'keefe in warsaw, poland, thank you. tonight the environmental protection agency has taken charge of the cleanup from the east palestine, ohio, train derailment site and ordered norfolk southern railway to pay for it. epa administrator michael regan returned there today, visiting several homes and meeting with residents. cbs's roxana saberi is there.

>> reporter: as medical issues mount in east palestine, so does mistrust. >> the combination of norfolk southern's corporate greed, incompetence, and lack of care for our residents is absolutely unacceptable to me. >> reporter: now the federal government is stepping up pressure on the rail operator. >> if the company fails to complete any action ordered by epa, the agency will immediately step in, conduct the work ourselves, and then force norfolk southern to pay triple in cost. >> reporter: today epa administrator michael regan and ohio governor mike dewine visited residents in their homes, even drinking the tap water. >> we don't mind proving to you that we believe the water is safe. >> reporter: the ohio department of health opened a clinic today to address residents' medical concerns. officials say the clinic here in east palestine was fully booked up today, but several residents told us they won't bother making an appointment because they

don't think they'll receive real help. matthew stokes works near the accident site. >> where is the mobile unit that they said was going to be here? there's no testing. there's not even a doctor on-site. >> reporter: the derailment contaminated at least 15,000 pounds of soil and more than a million gallons of water according to norfolk southern. today the secretary of transportation called on the rail industry to take immediate action to improve safety. >> i'm very frustrated because norfolk southern has been part of a wall of opposition from the railroad industry for years on safety regulation. >> reporter: norfolk southern said today it has been paying for cleanup and that it will stay in east palestine as long as it takes. former president trump is expected to visit the town tomorrow to meet with residents. he won this county in 2020. norah. >> roxana saberi, thank you so much. well, there was another freight train derailment today in central nebraska. more than 30 union pacific cars

♪♪ >> announcer: this is the "cbs overnight news." more than 60 million americans across 23 states are under winter weather alerts tonight with six states under blizzard warnings. the alerts stretch from washington state to maine, but the biggest impact is expected in minneapolis, which is on track for the second biggest snowfall of all time. let's bring in meteorologist mike bettes from our partners at the weather channel. good evening, mike. >> norah, good evening to you. we have a major blockbuster winter storm pushing through the midwest over the next two days. places like minneapolis, we take you there virtually. light snow gives way to heavy snow over the next two days and

very gusty winds in excess of 40 miles per hour. let's break down the forecast. we've had one 15-inch snowstorm already this season. this will make number two. double-digit snows around the twin cities. snow emergencies declared here. very difficult travel conditions, if not impossible across the midwest with winds gusting 40 to 50 miles an hour across i-90, i-80, i-29 and i-35 and a foot of snow or more in some pockets. then there's the ice. really heavy ice anticipated across southern michigan, including detroit. half inch to three quarters of an inch. this will bring traffic to a standstill, norah, not to mention with this kind of ice, we're anticipating widespread power outages. >> mike bettes, thank you. now to a dramatic moment in the double murder trial of alex murdaugh. the once prominent attorney is accused of killing his wife and youngest son at their south carolina home in june of 2021. well, today murdaugh's oldest son took the stand and described his father's behavior the night his mother and brother were killed. cbs's nikki battiste is at the courthouse. >> reporter: on the stand today,

alex murdaugh's surviving son buster spoke publicly for the first time about the night his mother, maggie, and brother, paul, were found dead. he says he rushed to his father's side. >> what was his demeanor? >> his demeanor was -- i mean he was destroyed. he was heartbroken. >> reporter: buster described his family as tight-knit and murdaugh as a devoted father. but prosecutors have painted murdaugh as a manipulative man who conned people out of millions of dollars for years. they claim murdaugh killed his wife and son in aan tempt to distract from a decade of financial crimes before they came to light as part of a separate civil case involving his son, paul, who was charged with boating under the influence in a crash that killed a 19-year-old girl. police body camera from the night of the murder shows murdaugh suggesting the boat crash as the killer's motive. >> my son was in a boat wreck. he's been getting threats. i know that's what it is. >> reporter: before wrapping its case last week, the prosecution showed jurors footage of

investigators questioning murdaugh two months after the murders. >> did you kill maggie? >> no. did i kill my wife? >> yes, sir. >> no, david. >> reporter: prosecutors also played video recorded by paul murdaugh just before his death, showing his father wearing a different outfit from the white t-shirt and shorts he had on when police arrived. cbs news legal analyst rikki klieman. >> so the prosecution may have been very, very effective, but it's getting to that motive that becomes the stretch. >> reporter: the defense team tells me they're considering putting alex murdaugh on the stand to testify. the defense also says they plan to wrap their case on friday, which means the jury would likely begin deliberations next week. norah. >> nikki battiste, thank you so much. tonight we're getting our first look at a new photo of that chinese spy balloon. this photo was taken from a u-2 spy plane earlier this month before a u.s. fighter jet shot it down off the south carolina coast. the pentagon says the navy has recovered all that remains of

that wreckage, and it was sent to an fbi laboratory for analysis. the supreme court heard arguments today in a case that could upend the internet as we know it. the argument is over whether popular tech companies like tiktok and google can be liable for harmful, user-generated content on their sites. cbs's jan crawford spoke with one mother who says the price of internet freedom is too high. >> reporter: 10 years old, always smiling, nyla anderson was a shining star. >> she was my butterfly. she was everything any mother could ask for. >> reporter: nyla died in december 2021 after attempting the so-called blackout challenge which she had seen on tiktok. she's one of at least 15 children aged 12 and under who have died in just 18 months as a result of the challenge. like other social media outlets, tiktok's algorithms recommend videos and other content to users. anderson said that feature led to nyla's death. >> they are actually feeding

into our children. they are sending them videos that they never even searched before. >> reporter: in a statement to cbs, tiktok said dangerous challenges are strictly prohibited on our platform and promptly removed if found. >> that's her twin brother. >> reporter: anderson sued tiktok and has filed papers in the case now before the supreme court that for the first time could hold tech companies accountable for some of the information and videos they are recommending to users. the companies say a 1996 federal law shields them from liability and that the modern internet would not exist if companies couldn't sort and recommend third-party content to users. free speech advocates say social media companies have rights similar to newspapers deciding what articles to publish. >> people criticize social media platforms today, and they have the right to criticize them, but they don't have the right to legally force them to publish certain content, to not recommend other types of content, and so on. >> reporter: but for anderson and other grieving parents, that has to change. >> how many more kids until it comes to an end?

how many more? that's my question to them. how many more children until this stops? >> reporter: a mother continuing to fight for answers. to fight for answers. jan crawford, cbs news, when cold symptoms keep you up, try vicks nyquil severe. just one dose starts to relieve 9 of your worst cold and flu symptoms, to help take you from 9 to none. for max-strength nighttime relief, nyquil severe.

requiring the fda to review certain chemicals that are banned overseas and to close what's known as the grass loophole, chemicals generally recognized as safe. this allows companies to skip an extensive safety review when adding many new chemicals to food. is the food industry basically policing itself? >> i would say yes. when you look around the world and you see what other countries are doing to protect their consumers, we are far behind. >> reporter: cbs news has obtained a copy of proposed legislation in california that would make it the first u.s. state to ban five common chemicals, including potassium bromate, from all foods sold, distributed, or made there. >> they're going to have to change their recipes, you know, to get rid of these chemicals, and hopefully that's something that's going to have impacts far beyond our borders here in the state of california. >> reporter: christina ochoa says the fda needs to do more. >> we're trusting them, and this is the food that is feeding our

future. and i want them to be held to a higher standard. >> reporter: now, in response, the fda tells us their scientists keep up to date on food safety research, but it says it's also the responsibility of the food industry to make sure the substances they use are safe. norah. >> ben tracy with that eye-opening report. thank you. well, we have important information for parents about another baby formula recall. what you need to know. want luxury hair repair that doesn't cost $50?

customers and a bit frugal. >> one time he was in here with rosalynn, and she wanted something for $5, and he yelled out, "$5?" >> reporter: from his naval academy yearbook -- >> that's mr. carter. >> reporter: -- to mugs, hats, stickers, books, and of course buttons from his presidential campaign. >> who wouldn't want you to give me jimmy? >> and this is from when? >> this is from '76. >> reporter: thousands of items reflect carter's 98 years. if you were designing a button about jimmy carter, what would it say? >> "a life very well done." >> reporter: a presidential pin that's priceless. nikole killion, cbs news, plains, georgia. and that's the overnight news for this wednesday. for some of you, the news continues. for others, check back later for "cbs mornings." and remember you can follow us online anytime at cbsnews.com. reporting from right here in the nation's capital, i'm norah o'donnell.
