>> win big or lose, that's the choice. most americans don't want the promise of revolution. they want more than pr they want results. ( cheers ) >> sreenivasan: when nbc's chuck todd asked this morning, if he belie"bernie sanders would lead the democratic party to a big loss," biden said: >> i do. i think bernie sanders's positnuions on er of the issues, even in the democratic party, are very controversial. >> sreenivasan: the former vice president received 48.4% to senator sanders 19.9%. third place finisher billioanire businesom steyer dropped out after get>>ng just 11.3%. said if i didn't see a path to winning that i'd suspend my campaign. and honestly, i can't see a path where i can win the presidency. >> sreenivasan: second place finisher bernie sanders conceded south carolina, putting the focus instead on super tuesday states including virginia-- where he held his rally last >> and that will note the only

defeat, there are a lot of states in this country, nobody wins them all. i want to congratulate joe biden on his vicry tonight. and now we enter super tuesday in virginia. ( cheers and applause ) >> sreenivasan: in the race to enough delegates to w the democratic nomination sanders now leads with 58, biden has 50 and former south bend indiana mayor pete buttigieg and senators elizabth warren and amy klobuchar are the only hers with delegates as of sunday afternoon. we will have more on what's facing the candidates on super tuesday when 14 states hold their democratic primaries erming up ahe news summary. the new coronavirus has now spread to more than 60 cotries and more confirmed cases are being reported in the united states. yesterday, washington state reported the first death from the virus. there are now more than 70 confirmed cases in the u.s., with officials in illinois and rhode island each reporting theiitfirst "presumed pose"

cases since yesterday. in france, where the number of cases is now mo than 100, the louvre museum closed its doors to visitors today. the government has canceled large indoor ic gatherings of more than 5,000. ia,n chhere the outbreak began two months ago, there were 573 new cases reported today. it's the first time in five days that the number has exceeded 500 new cases. r more on the washington state outbreak, "los angeles times" seattle bureau chief richard reed joins us now. wht at the latere? any new cases that are reported? >> yes, today there are two more people, men in their 60's who are in critical condition he after contracting the virus. related to the facility, the long term care facility that we were talking about or interest in yesterda >> i don't believe it is, and that's part of what's concerning officials, we haven't gotten a lot of details about these two men, but the person who died, a man in his 50's, had underlying

apparently not connected to this nursing facility where they' having an outbreak. >> sreenivasan: so how do we, if it's not somebody that is connected to that facility, does that mean that he got it from somebody ee, somewhere else? >> the strange thing about him, it's a mystery. so faryou know, they know that he wasn't traveling and there's no known contact that he had with a coronavirus patient. that's what's concerning the authorities. he ended up dyinat a hospital in kirkland, which is the same hospital that one of the nursing home patients was sent to. and apparently they had never crsed paths before. >> sreenivasan: are the people in that nursing home being tested, or what were the results if they were so concerned about th spot? >> yes, they're about 50

residents and staff there o have respiratoptoms. and so the c.d.c. is sending a ateam of ten to investiga to take over the organizing, the testing. for some reason, they're not testing th athe facility. so from what we're told, they have to bring themut to a local hospital for tests and en back there again. >> sreenivasan: and you nt there earlier today. what was the scene like? >> i spoke to some of the neighbors. theusy're anxas you might pect. ano d they're tryingke precautions. they've disinfected their own homes. they're, a couple of them were heading out to a grocery store to get supplies in case they're told to stay inside. so it's-- it's a developing situation around that neighborhood. >>treenivasan: are there a of people in the seattle area that are heading to grocery stores and trying to stock up now? >> yes, i would say there are. i mean, when you walk around the

downtown here, you don't see people in masks or it looks pr mettyh the same. but if you go to costco, there are lines out front of the store. people running in to get things. some of their grocery store aisles, the aisles with thete or the medical supplies are getting very bare. >> srnivasan: and finally, i want to ask also about that teenager. >> the high school student. again, that's a mystery. he got tested when he hadsp atory symptoms and he was waiting for the test results and was feeling better. so, on friy, he went to school briefly. and then frida back positive. and so now thatchool is being sinfected, it will be closed on monday. the same with another school in oregon. > r> sreenivasahard reed, the seattle bureau chief for the "l.a. times," joining us via skype tonight. thanks so much. >> happy to do it. >> sreenivasan: the path to peace in afghanistan hit it's first snag todne day after the u.s. and the taliban signed

a conditional peace agreement. aprfghaident ashraf ghani told reporters in kabul today that he will not free as many as 5,000 taliban fighters as part of a prisoner exchange program. the taliban would be required to release 1,000 afghan prisoners. the exchange is seen as a confidence boosting measure between the afghan government and the taliban before intra- afghan power sharing talks begin next week in oslo, norway. thousands of syrian migrants ontinued to gather at turkey's bordewith greece today in hopes of entering eure. syrians fleeing civil war have overwhelmed greek authorities since turkey opened i border yestday. the greek army and police have responded with tear gas and sadn gren to repel the migrants from entering the country. turkey's president recep tayyip erdogan has frequently threatened to allow refugees and migrants into europe unless more international support is provided.

>> sreenivasan: super tuesday is going to come down to one major factor for the democratic presidential contenders: delegates. and getting those delegates means that candidates have to meet a key threshold to make it to the convention. newshour weekend special correspondent jeff greenfield explains. >>in we're briour people together! ( cheers and applause ) >e > mbers are staggering: 14 states and one territory from one end of the continent to the other. >> this is a moment, and it's >> 1,357 delegates at stake. >we're gonna show them, aem surprise >> millions of voters, tens of millions of advertising dollars. but if you're looking for a number that will determine the there's really only one that matters: getting 15% of the vo. why? it's because of the ground rules fohodemocrats award delegates in the primaries. >> well, they're very significant. isd one way to understand is to compare the democratic rulethe republican rules. >> there's no better guide to the way democrats choose their nominees than elaine kamar;

she has been a member of the party's rules committee for more than two decades and literally wrote the book on how americans ndminate presidential ates. >> so the democratic rules tend to favor, not losers, but the second place finishers. whereas the republican party rules tend to be winner-take-all by congressional district. >> democrats do award some delegates to a state's overall winner, but most of the delegates are based on how well they do in individual congressional districts. for comparison, just look at the ampaign. when donald trump won the new york republican primary with 60% of the vote, he won 93% of the states' delegates. when hillary clinton won the new york democratic primy with 58% of the vote, she got about 56% of the delegates, withenator bernie sanders collecting the rest. because democrats do not hav winner-take-all rules, you can win a fair number of delegates without actually winning a primary at all. but there's a catch: that 15%

threshold can also dramatically boost a front-runner in a crowded field. take senator sanders and california, with its 415 pledged delegates. polls not only show sanders with a large statewide lead, they show every other candidate struggli to hit 15%. if no one else gets above that mark, sanders would get all of the 144 statewe delegates. that's about a third of all the delegates in the state. if that holds true in many of districts, sanders would get the lion's share of those remaining delegates as well.so t is conceivable that a y ndidate like sanders could win a huge majorit the delegates, with far less than a majority of vo bot those same rules that ost a contender in a crowded field, can also make gaining grnd in a narrowed field very hard. in the last two contested democratic primaries-- 2008 and 2016or the were only two maj candidates, so getting to that 15% threshold wasn't hard at

al but making up serious ground was also nearly impossible with no winner-take-all contests. that's what doomed clinton in her race against barack obama in 2008-- and it's what guaranteed her victory over sanders last time out. s was winning enormous margins in the south. so her delegate lead over bernie sanders essentially carrd her through the rest of the season. and righnvon into the tion. >> that's a similar dynamic we y could see thisear: if sanders solidifies a significant delesugate lead after r tuesday, even a winnowed field will have a ha time catching up. with joe bien's landslide win in south carolina last night, here are the crucial questions super tuesday might answer: first, can biden w most of those southern states where there is a significant black electorate? cond, what happens if none of the moderates drop out between now and tuesday?

would o divide the vote that none of them hits that 15% mark? and third, what if bloomberg-- despite his massive advertising, including prime time speeches tonight on cbs and nbc-- finishes far behind biden in the voting? a little more than8 hours from now, super tuesday might give us much more clarity about the democratic field-- or leave it even more muddled than it is now. hari? >> sreenivasan: jeff, what about >> sreen greenfield joining us from california tonight. thanks so much. >> thank you, hari. >> sre coverage of the 2020 race ahead of super tuesday visit pbs.org/newshour. >> sreenivasan: you may not know the name jim marshall, but you certainly know his photographs. collectively, his workne complete account of the counter cultural revolution, from photographing jazz clubs in the 1950s to backstage images with the beatles and woodstock, few photographers covered as much ground as well as jim marshall. tably talented, notably difficult, his longtime life, and helped hate a daily

massive photography archive, mpiling his most iconic images into a book and documentary-- ryhow me the picture: thes of jim marshall." newshour weekend's christopher booker has more. >> reporter: there are two ways to consider the photographs of im marshal first, the technical. few photographers working in the '60s and '70s could match his ability to work with and use natural light-- the contrast in his images are a roadmap in how to exploit darks and lights. and second, proximity. backstage and up-close, his photos are unguarded-- snapshots from the view-point of a very ose friend. but to consider the work of jim marshall, you must also consider the way jim marshall worked. a process his longtime assistant amelia davis recently tried to explain in her documentary, "show me the picture: the story of jim marshall." >> look at my work. look at my track record over 20 years of taking pictures. look at my body of work.

think it works? >> reporter: davis, also a phpher, met marshall after college when he was looking for an assistant to work out of his home office. t>> we wehis apartment and then i saw iconic photo after iconic photo, johy cash flipping the bird, the beatles coming on the stage at candlestick park. jimi burning his guitar. and i w mortified. and i said, "oh, my god. i hado idea that was you." and he smiled and he said, "that's why i liked you." learn, as many had before, working with jim marshall was not a simple proposition. >> you either loved or hated jim and he either loved or hated you. and if he loved you, he was so generous and he would lay down in front of a, you know, oncoming truck. if he hated you, he would be the driver in that truck that ran you down. so, that's the way jim was. >> reporter: at least there is no middle ground there. >> there is no middle ground whatsoever. >> reporter: born and raised in san francisco, marshall picked u ap a cameer his time in the air force, taking photos in

jazz clubs in the late '50s. while his music photos made him chronicling verty and the civil rights movement throughout the south. >> jim always wore abve leicas around his neck. and he would always, the minute you started talking to him, he would just start c, cking away. at first, people were like, oh, my god. but then you forget. they would forget th had a camera. and they really opened up. and i always like to say at with jim's photography, i never feel like i'm a voyeur. you feel like you're there. >> reporter: one of marshall's earliest relationships was with john coltrane. marshall met the saxophone and marshall would go on to1960 produce some of the most indelible images of the jazz legend. most notably, a portrait of coltrane on the street in queens. there were more. bob dylan in greenwich village, johnny cash at folsom prison, and miles vis in the boxing ring. but with his success, came excess. >> i've always liked cars, guns cars and guns have gotten me in

trouble, cameras haven't. grew, so, too, did his reputation for being abrasive and difficult to work with. a situation made only worse by a growing cocaine addiction-- one that would lead to arrests and a gun conviction. >> i met jim later on in his career in 1998. so, he really wasn't doing a lot of hephotography. as living off of his photographs. i mean, he was, he was really well known at that point. he was selling in galleries. he did a lot of licensing. so he really didn't have to work anymo. and he was still doing a lot of cocaine. >>eporter: you actually quit the job twice and came back twice. > i did, i did. >> reporter: what made you come back both times ? >> i kept coming back because it was the photography. wu know, there this incredible photographer that took these amazinpieces of history. and i just thought it would be

horrible if this was lost. >> reporter: but there was a commercial benefit to marshall's mercurial nature-- his refusal to sign away the rights to his work proved to be a prescnt decision. >> jim was fiercely protective so he early on said, "i'm never gonna be a work for hire. i'm not going to work for a label where they own my photogra the only way i'm going to work for somebody is an independent contractor, because then i own the photographs. a it did cost him, you know, early on. it cost him a lot of jobs. buhe was ahead of his time because then he owned those copyrights. >> reporter: i mean, what's asinnishing is ng of the time. i mean, the beatles weren't even thinking this way. >> i know. >> reporter: paul mccahas very famously been trying to get back his publishing rights. even acts like that weren't ththinking about protectineir copyright. >> i know. reporter: why do you think he had that instt ct? >> i doow. it's really interesting. it's one of those things. and same with photography.

i mean, he was self-taught. he didn't go to school. so, he was one of those rare cases where his brain, he could be really creative, but he could also be very orgized and business-like. where a lot of artists aren't. >> reporter: do you think jim could work and succeed as he did in this era? >> no. he would piss somebody off so much, no, he would not be able to. >> reporter: jim marshall died in his sleep in 2010, leavingch his e to amelia davis. now you are serving really as the steward and protector of his work. what happens to jim's work and all of these images? >> so, we do a lot of books. we do a lot of shows. one of the reasons i did want to do the doccoentary was to nnect the name to the photographs, because everybody who's seen jim marshall they're jim marshally don't know photographs. and especially now we're looking

50 years later at a lot of these historical ents and we can learn from them what worked, what didn't. and be inspired with what jim did. >> sreenivasan: once a year, california's yosemite national park plays host to an impressive trick of sunlit and water on the vertical rock formation known as el capitan. but warmer weather this year lead to disappointment. christopher booker has more. >> reporter: for a few weeks each february, a natural spectacle draws thsands of people to california's yosemite national park. it's called fire fall. it only lasts for a few minutes at sunset, when the winter lig hits the park's towering horse glil falls at just the right but this year there was no fire fall. patrick gonzalez is a professor with the university of

california, berkeley. he says this year there wasn't enough water.at the reason: clchange. >> the more snow that you have in the winter, the more water that you'll have coming over the falls. our analyses show that total annual rainfall and snowfall has decreased across all of yosemite national park. >> reporter: and gonzales says fire fall is not the only part of the park that's being impacted by climate change. >> our analyses of climate data show that human caused climate change has heated the park 1.1 degrees celsius orwo degrees fahrenheit. outhat might not like a lot, but 1.1 degrees celsius is the equivalent of pushing a mountain down 180 meters, or 600 feet more than the height of the washington monument, from cooler areas at high elevation to warmer areas below. in yoseme and across the western u.s. human caused climate change has doubled the

area of wildfire bned, has doubled tree death a has shifted trees upslope into meadows. >> reporter: in recent years, due to concerns over the ecological damage that come with yosemite, the national park service has tried to limit the number of people who come to watch fire fall, but as the climate continues to change, such restrictions may no longer be necessary. >> sreenivasan: wis than 48 hours to go before the next polls open, you can find the latest campaign news online at pbs.org/newshour. tomorrow, newshour reporters will be in super tuesday states democratic presidential nomination. that's all for this edition of" pbs newshour weekend."i'
