>> i certainly think that the evidence has been produced overwhelmingly shows serious misconduct from the president, but i do want to hear more from my constituents and more from my colleagues. this is not a decision i will bi alone. >> sreenivasan: on the other side, republican members of congress and officls from the trump administration took turns arguing there is no evidence of impeachable offenses. congress is on a thanksgivg recess this week. when representatives return, they will also face a budget deadline. without a funding agreement for more than a dozen federales agenn place by december 20 there would be a partial government shutdown. with the iowa caucuses ten weeks away, billionaire and former new york city mayor michael bloomberg officially entered the democratic race for president today. the 77-year-old former republican launched a $30 million dollar one week-long television ad campaigno dozen markets across the country. >> mike bloomberg for president: jobs creator, leader, problem

lver. it's going to take all three to rebuild a country. >> sreenivasan: his democratic rivals are criticizing bloomberg for using his wealth to buy into the race and for a lack of grassroots support. bloomberg's chief adviser howard wolfson said the billiaire has" never taken a political contribution in his life" and "" cannot be bought." supreme courjustice ruth bader ginsburg was released from the hospital today after being admitted for "chills and fever" on friday. statements from the supreme court reported the 86-year-old justice was given intravenous antibiotics and fluids and is now recovering at home.as ginsburgad a number of health scares recently. earlier this month, she missed oral arguments due to a "stomach bug" and she has bn treated twice for cancer in the past year. in japan today, pope franc declared the possession and use of nuclear weapons to be an immoral crime as he visited memorials to the victims of the 1945 u.s. atomic bombings ofsh hia and nagasaki.

in nagasaki, the pope laid a wreath of flowers and warned against the erosion of arms control agreements. >> ( translated ): the manufacture, upgrading, maintenance and sale of ever more destructive weapons, are an afont crying out to heaven >> sreenivasan: the pope then traveled to hiroshima, offering a prayer andighting a candle during a nighttime ceremony that included testimony from two survivor more than 200,000 people died when the united states dropped atomic bombs on hiroima and nagasaki in august of 1945. for continuing coverage of theem 20ratic presidential race, visit pbs.org/newshour. : >> sreenivaso-democracy support in hong kong was tested at the polls today as residents voted in local district councilc ons. turnout was high and the vote was peaceful, in contrast to the violent anti-government dednstrations that have pit hong kong's government against pro-democracy demonstrators over

the past six months. 452 seats were at stake in hong kong's 18 district councils and the results are expected to be a referendum on the conflict.g joininus now via skype from hong kong is "new york times" reporter austin ramzy. >> sreenivasan: austin, we saw the picturesf people lined up. how significant was this turnout? >> the turnout was huge. 71 percent of eligible voters almost 3 million people, longli s, 0 at lots of polling stations around the city, huge tere in this, this election. >> sreenivasan: state comes down to the pro beijing party are those the two kind ofty. biggest ones that are fighting for all of these smaller seats? >> yes. i mean, it is divided among seral parties and several unaffiliated candidates, but those are te o largest camps, the sort of establishment, pro beijing and then the pro democracy camp. >> sreenivasan: and what is the ripple effect of this

election? is in what decis the legislative council that makes rules or how does -- i mean, otherwise we would not be talking about a relatively small city council election. >> that's right. it is surprising that there has been so much interest and focus thetrict council deals with very local issues, as i saw the candidates campaigning in my neighborhood that signs about, you know, trash cleanup bus stop placement and taking care ofak air conditioners that were dripping from buildings, very, very local things like tht. but they do have a role in selecting the chi executive on sort of an uncvoluted democratic system, achieve executive is chosen by a panelbo of 1,200 people and the district councils choose about 120 of those, or about 10 percent of thesse. so it ave a role in choosing a top office, but theot r reason this rote is so

important is it has been a referendum on the -- >> sreenivasan: while you ande i alking, they are still counting the votes and it is kind of too early to say exactly how th election is breaking at the moment, but let's say, for goample, let's kind of through both scenarios. >> if the pro beijing party has a, whatever a decisive win and they are the ones that ll be electing the kind of chief executive of hong kong, what doeshat say to the demonstrators? are they going to say, okay, well, we lost this round, that's it, no more protests? >> yes. if that scenario were to happen, and -- it sems like a less likely of the scenari, it would sort of say that people have had enough, people are tired of the disruption related to this and would start moving toward the establishment. the pro beijing camp has traditionally won this election because it has more money and it th better organized a very

grass roots level so they hae won thislection eve since e a part ofec china. >> sreenivasan: let's try the inverse if the pro dem wocracy cas the election what does that signal to china? >> that would be quite a big shock. as i said, you know, this is an election that sort of has been controlled by the pro establishmenamp, and as returns are coming in we already have seen some very prominent names -- pro democrats have picked up a lot of seats but we don't l ow if it w enough seats to control all of the councils but a signmbificant of seats and we will sort of -- this is the first time where those numrs of people that have been on the street have actually been able to votei and it really propose those numbers will have some meaning. austin ramzy of the "new york mes" joining us via skype from honhong kong. thank you so much. >> my pleasure.

>> >> sreenivasan: it's beemore than 200 years since a group of enslaved black men and women launched an uprising in modernhe day st. johnaptist parish, louisiana. it lasted only a few days beford the poorly aebels were crushed by a local militia and u.s. army troops. many were caured and convicted of insurrection. but now, two centuries later, an artist has staged his own version ofhat fateful event. newshour weekend special correspondent, brian palmer ha the story. >> reporter: if we could step back in time to nuy 8, 1811, to the territory of orleans, to the porch of a plantation owner named manuel andry we might come across a scene similar to this. >> why are you doing this? haven't i been a master that's treated you with love an understanding? charles, why? >> reporter: it's a qu only an owner of people could

ask of the very people he owned. andry wasn't killed that day some 200 years ago. but on this day, in 2019, he met a different fate. ( cheering ) this performance is part of a reenactment six years in the making, a reimagining ol what many ss consider to be the largest slame uprising in ican history. so i want to ask you why. why do this? >> this history needs to be known. participated in this revolt of they were-- had thd vision of getting free the only way they could, not by individually escaping or not by even escaping with a few people and forming a maroon colony-each of which would have been righteous-- but actually by overthrowing the system of enslavemt. >> reporter: during the reenactment, we spoke with the organizer, artist dreascott, whose adopted name is a nod to 19th-century enslaved man who

took his case for freedom allto the wahe supreme court. he lost, and so did millions of other ericans when the majority of justices held in 1857 that a black person, no rights which the mand, "had was bound to respect."bu decades before, a man called charles deslondes had set out to change that. went from plantation tolondes plantation and he recruitedpe le to be participants in this rebellion, and he recruited his lieutenants and they in turn recruited the other people on >> reporter: under leadership of deslondes, an enslaved plantation overseer, and others, more tha200 men and women rose up against their enslavers. the goal: to make their way 30 miles east to the capital of the territory, new orleans, seize the city by force and create ae new nation fre slavery. >> wer'e going to end slavery.

we're going to end sla >> reporter: over a two-day peri this month hundreds of reenactors, including scott, traced a route similar to the more than miles covered back in 1811. the original rebels took machetes and musts from plantations where they had bee held in bondage. these 21st-century rolplayers wore 19th-century costumes and carried those same weapons as they marched along the levees of the mississippi river shouting freedom chants in english and creole. >> i talked with a handful of people about participating in this. some of them were hearing aboutr thellion for the first time, but when they heard about it, they're like, we need to make this known.ng and reenact would be amazing. and so they in turn recruited the other people. they became sort of the lieutenants in the army of the enslaved and recruited others. >> reporter: this coy engagement included hands-on activities to prepare. there were sewing circles to crea costumes and night rehearsals to map out the steps of a battle between the "army of the enslaved" and the local militia whe job it was to

police african american bodies. volunteers came from across the country to participate. >> so, as you know, we're in these period-specific costum with a mesh of modern jewelry and sneakers, we as performers and anyone who sees us will be forced to question what does liberation look like for black folks? liberty! reporter: jordan rome traveled from chicago to take part. it was only this summer that she first learned of the historic 1811 reblion. but she's since found inspiration in this story of resistance.re >> they illing to die free. for some of those enslaved folks, simply holding a weapon in their hands was freedomjust because they had no autonomy over their bodies. didn't result in an independent nation. in fact, many of the men and women who rose up against slavery never made it to newor ans. they were attacked and killed by

u.s. troops and local militia and those who survived were tried hastily by the very people who had enslaved them. but that only one part of the story. story, which had abrutaltual ending, with art. >> yes. m reporter: explain that >> this is a project about freedom and emancipation. slavery. a project about it's a project about freedom of getting free byhrowingision the syem of enslavement. and as an artwork, i can say i don't want to focus brutality of white people. i mean, everybody knows that white people were brutal during slavery if you think about it for a second. but this is a project that actually can focus on the agency and self-determinatithe enslaved people, africans and people of african descent, yearning tbe free and making a plan to do that. ♪ to freedom land i'm on my way ♪ >> reporter: scott sthe slave rebelln reactment as part of a life's work that seeks ask hard questions abou americs past and present. he drew national attention-- and

heavy criticm-- in 1989 for an art installation he called "what is the proper way to display a u.s. flag?"vi tors could step on an american flag while interacting with the art. in 2015, he made headlines for adaptation of a famous anti-lynching banner that hung from the new york office of the n.a.a.c.p. in 1936. in scott's updated version the flags' original words "a man war lynched yey" were replaced with "a man was lynched by police yesterday" equating police brutality with lynching. it's an extension of the argument made by many contemporary scholars-- and the black that not only present day police killings, but also mass incarceration grow out of a long history of over policing black people. >> first there was slavery, then there was jim crow, and now there's the new jim crow. million people in prison, and about 1.1 million of those are black. that grows out almost dictly

from the system of enslavement.n there is no momerica without slavery. the leaders in 1811 had this idea of getting free.ca not, again, esping, but overthrowing the system of enslavement. that was r>>lly radical. eporter: for scott to tell this story is to reveal a piece of hidden american history. toeell it from the perspect of the black men and women who rose uto liberate themselves is to give voice to those who were silend by execution-- and in the pages of history, which was written by theeople who enslaved them. scott hopes this perrmance will make people reevaluate what they think they know about this period and how slavery ispr ented today on plantation tours that focus on the life side the "big house," th masters residence. >> these are sites of genocide. they're sites of genocide, and yet they're set up in a way that people take tours that whitewash the history, and other people come to have their wedding there. who would have their wedding at auhwitz? who would do that? but there's a whole tourist industry thas built on making

people look back in a romantic way to sipping mint juleps on their veranda and understanding these slave labor camps from the perspective of the enslavers. >> t boston tea party member the founding fathers, they fought for their freedom. you know? and these people did the same thing. they wanted to be free. >> reporter: ibrahima se is the director of research at the whitney plantation museum, which tells the story of slavery from the point of view of those hel in bondage. he also took part in the reenactment.le >> what peon't know is that enslaved people always thsisted. always fought r freedom. from the beginning when they were being deported in africa, too. th, revolt aboard slave shi hundreds of revolts. and once they were brought over here, too. >> reporter: it's with this spirit of resistance that the reenactors reached a destination that the 1811 rebels never did. rethey marched through thench quarter in new orleans, past

curious tourists and local and entered congo square, a gathering place for enslaved onople in the 19th century on the occa days off that they were grted. >> so, the most radical ideas of freedom at that time were in the heads of the enslaved people. and that's something for modernp day to both understand but also to learn from. >> reporter: and for historian ibrahima seck, as well as artist dread scott, rid historical accuracy is not the point of is event. >> what these pethle got from is 1811 is a song that will g ver die. and that's the syou heard on congo square. i thinthese ancestors are really happy. i think i could even feel their presence at congsquare. ♪ ♪t that great? as >> sreen: a recent study published in "science magazine" found gnificant racial biasus

in an algorith by hospitals across the nation to determine who needs follow up care and who does no megan thompson recently spoke with "stats" shraddha chakradhar, who explained what the researchers found. >> tmpson: where exactly was this bias coming from? >> there are two ways that we can identify how sick a person is. one is how many doars are spent on that person. you know, the assumption being the more healthcare they come in for, the more treatment that lars they the more d spend. and presumably the sicker they are if they're getting all that treatment. and the other way is that, you know, we can measure, actual gsbiophysical thyou know, from lab tests to what kind of conditions or diseases they might have. t so it seems lis algorithm was relying on the cost prediction definition. in other words, the more dollars a patient was projected to spend onhe part of an insurance

company or a hospital, then that was a sign of how sick they we going to be. um, and that seems to be where the bias emerged. >> thompson: i understand that the researchers then sort of re-- use the algorithm using a can you just tell us a little bit more about that? what did they use? >> yeah, so instead of relyingt on jsts to predict which patients are going to need t follow up cay actually use biometric data, physical-- biophysical data, physiologil data. um, and they saw aenramatic diff. you know, in the previous model, the gorithm missed some 48,0 extra chronic conditions that african american patients had. but when they rejiggered the algorithm to look more at actual biologal data, they brought that down to about 7,700. so it was about an 84% reduction in bias. >> thompson: do we know anything

about how the use of this biased algorithm actually affectedti t care? >> um, we don't actually know that but, as i mentioned, the algorithm is used by hospitals to help them flag patients who might need extra care in the coming year. whether it's, you know, an at home nurse or making sure that they come in for regularly scheduled doctor's appointments. so, we can only presume that if black patients-- sicker black patients weren't being flagged accurately that they also missed out on this follow up care. consequences for the company, optum, that was behind this algorithm?>> eah. so, the day after the study camt out,lly, new york cegulators, the department of financial serand the department of health sent a attter to the company saying they were investg this algorithm and that the company had to show that the way the

algorithm worked wasn't inof violationti discrimination laws in new york. so that investigation is pending. one encouraging thing is that when the researchers did the study, they actually reached back to optum and let them know about the direpancy in the data, and the company was glad to be told about it. and, um, i'm told that they're working on a fix, um, and the othe the other encouraging thing is that the researchers have actually now launched an initiative to help other companies who may be behind similar algorithms, to help them fix any biases in their programs. so, they've launched a program based out of t university of chicago's booth school to do this work on a pro bono basis so that they can sort of catch these things in other alhtrithms that me used across the country. >> thompson: all right. shraddha chakradhar of "stat." thank you so much for ing with us. >> thank you for having me.

>> this is pbs newshour weekend, sunday. >> sreenivasan: and an update on a story newshour weekend's ivette feliciano reported this month on good samaritan prosecutions against people migrants along the u.s.-mexico border. the organization "no more deaths" co-founder reverend john dfife explained how tacti on him three decades ago, were on the rise again. >> reporter: as an oained presbyterian minister, fife was arrest back in 1985, after his congregation bece the first religious institution in the u.s. to offer sanctuary to migrants who faced deportion. 2018, no more deaths volunteer scott warren was arrested onr simiarges for allegedly harboring and shielding twora undocumented ms from law enforcement at the group's base camp in ajo, arizona.

fife contends warren was simply providing humanitarig aid in keepth no more deaths protocol. >> he gave food and water and me medical care to two migrants who just showed up at our base camp. >> reporter: but in court documents, federal prosecutors disputed that claim, arguing medical attention, nor were the people associated with the charges in distress. they also said he was "notqu ed by his beliefs to aid in the evasion of law enforcement." warren's first trial ended in a mistrial after jurors couldn't reach a verdict, but federal prosecutors will see to retry him this week on two felony harboring charges. >> senivasan: last week a federal jury in tucson, found scott warren notchuilty of the arges.

>> sreenivasan: finally tonight, it's thanksgiving holiday travel time and unfortunately, you might need to plan for some delays. starting tuesday, snow and rain are expected on the west coast with a second storm system hitting the central part of thtr co that storm will move into the eastern and southern states on wednesday., the 55 million people triple-a says will travel more than 50 miles from home for the holiday, stay safe. and happy thanksgiving to all. that's all for this edition of" pbs newshour weekend." i'm hari sreenivasan. anks for watchg. have a good night. captioning sponsored by wnet captioned by media access group at wgbh access.wgbh.org >> pbs newshour weekend is made possible by: bernard and irene schwartz.
