can't be seen in real life. we are learning more about the victims and the heroes involved in the london terror attack. outrage in iraq as protesters clash with police as they celebrate the prime minister's promise to resign. also, wicked winter weather. parts of the u.s. getting pummeled on the busiest travel day of the year. and welcome to our viewers in the united states and all around the world. live in atlanta, i'm michael holmes here at cnn world headquarters. cnn "newsroom" starts right now.

welcome, everyone. british media reporting the justice ministry is reviewing every parolee. the action comes after a convicted terrorist on parole stabbed five people near london bridge on friday. bystanders rushing the man with a fire ex extinguisher and a narwhal tusk. he was later shot and killed by police moments later. mike bolton covering the story for us in london. brings us up to date on the investigation. and of course we're learning about at least one of the victims. >> reporter: yes. we've been told one of the victims killed on friday was a

25-year-old man, a graduate of cambridge university who was on site. a released prisoner, try ig to help rehabilitate toes. his father has spoken of him having a beautiful soul. he said he was a champion of the underdogs, hence the reason he was involved in rehabilitation. he had a wonderful and brilliant spirit. others involved, those who had become friends of his because of the rehabilitation talked highly of his character. one saying he stood by me when society didn't. that adds to the sadness of this whole thing. an easement put on to help those who improve their lives. one of those people turns and kills one of those trying to help. we know also there was another woman killed and three people are in hospital still.

nhs said one of those three people's conditions have improved. so all three are stable. one man and two women are still being treated in london's hospitals. >> with this review of other cases that we just mentioned and various comments by politicians, is this going to be coming or has it become a political issue with the upcoming elections? >> reporter: you know all too well, michael, it will. generally there was a period of grace where people pay tribute to those services and the individual acts of bravery we saw on friday. then the political fallout comes. well, there is a general election in less than two weeks. no grace period. political points scoring has begun already. boris johnson said yesterday tariffs should be served in full. he served less than half of his sentence. he said he wants to clamp down

on that. the difference we understand being that he was believed to be wearing a suicide vest, so he still posed a threat. in ireland the shoot to kill policy was criticized when the assailants could be detained instead. i think generally people feel the criminal justice system has major loopholes that need filling. this will no doubt be front and center stage of the rest of the general election campaign between now and december 12th. >> thank you, mark. mark bolton reporting there. teachers at the london school of

economics joins us now to talk more about this. khan was a man at a conference focusing on the rehabilitation of prisoners. it clearly did not work with him. what are the challenges of deradicalization? what makes it work, what makes it fail? >> reporter: it is extremely difficult to say what are the drivers behind deradicalization? there is no magical wand. it depends on every particular case tomorrow. the record is extremely -- there is nothing really that shows a perfect system. here you will have khan, who spent eight years in prison. he wanted to be out. he said quote, unquote, he wanted to be a good british citizen and contribute to society.

yet less than a year after he was released he went on a killing spree. what the big point about really khan's case is that the lone wolf phenomenon is very resilient. he was part of a very radicalized hard-core radicalized cell. the attacks in europe the past few years have declined substantially. just to give your viewers a glimpse of what we're talking about, in 2015, 150 attacks occurred in europe, according to the european union figures. only 13 attacks occurred in 2018. and also the gravity of the attacks. now we are talking mainly about lone wolf attacks as opposed to coordinated multiple attacks by limited cells all over europe.

>> right. the thing about this incident, it is likely, is it not, to color the debate over the repatriation of isis suspects in syria, even those who have gone through the system and were convicted, slipping through the cracks. it does speak to that challenge of rehabilitation of jihadists. >> reporter: i mean, yes. to give you an idea here in london, in the uk, you have almost 100. i mean, basically individual radicalized individuals who are in the prison system. one thing we're not talking about, you have 800 active ongoing terrorist investigations taking place in the uk today. so not only do you have between 70 and 100 basically convicted individuals who either plotted or carried out terrorist attacks, you have 800 active

cases. just in 2017. more than two dozen attacks were basically, i mean, found out before the attacks took place. they were basically preempted by the british authorities. and i think the system itself is overwhelmed. there is not really much resources, are there, either in terms of the judicial system or the police system. that's why it has become a politically, i mean, big case in the coming elections in britain. the conservative government has not really invested considerably in trying to manage this particular problem. >> it does speak to -- i mean, the authorities, as good a job they can do, they have stopped many. but it only takes one to slip through. speak to the state of isis. you have had the death of

baghdadi. people want to make a point of we're not going yet. >> reporter: i think we should tell our audience the good news first. the good news is the isis wave has lost much of its momentum in the past two years. think how the landscape was in 2015. the attacks in germany, france, belgium, uk. multiple coordinated, i mean, devastating attacks. hundreds of casualties. now we are dealing with -- even though it is very vicious, very painful, we are talking mainly lone wolf deluded individualsen expired either by isis or by al

qaeda. khan was part of an al qaeda cell. my take on it is the lone wolf phenomenon is here to stay for a while. because you have individuals who are radicalized online. what we're talking about here, we are talking about an ideology that is traveling. of jihadism. politically inspired zones. you will have an individual like khan who basically are radicalized online and they create these small limited cells and do what they do. sadly and tragically, these a, ta, even though they are limited, their impact is tremendous. even though here in the uk, you have hundreds of stabbings. one attack in terms of lone wolf is magnified because it is random and individuals really do

not know, people do not really know, you know, how it comes and where it comes from and whatever. >> as we saw, the police response was almost immediate. yet the damage was done. they are easy to carry out. you make the point ideology is still there. you cannot beat that with bullets. good to see you. thank you. >> reporter: thank you. as president trump gears up for a big summit in london this week, some people who could decide the fate of his presidency, are waiting to hear from him and his people. also, the u.s. is about to be walloped by a massive winter storm coast to coast. we'll have a live report coming up.

welcome back. the u.s. president donald trump finishing his thanksgiving holiday at mar-a-lago in florida before heading back to the white house in a few hours from now. it is shaping up to be a big week for his administration on capitol hill. the house judiciary committee set to hold its first

impeachment hearing. mr. trump will be in london for the nato summit. still, he has a decision to make and deadlines are looming. >> reporter: no decision so far from the white house as it relates to this first impeachment deadline sunday 6:00 p.m. eastern. the white house needs to decide whether or not the president will send an attorney to represent him at the first impeachment hearing hosted by the house judiciary committee. that is coming up on wednesday. but there is a second more critical deadline, and that is coming up on friday by which time the white house needs to decide whether the president or any of his attorneys will participate in any of the impeachment hearings held by the house judiciary committee. something house democrats are likely to move forward with in the coming weeks. so far the white house has not indicated one way or the other. here is the core question that the white house faces. the president has of course been

extremely critical of the impeachment proceedings calling it a hoax and scam. he doesn't want to legitimize it by sending attorneys. he has not been able to have an attorney present at any of the impeachment proceedings thus far. those have unfolded on the house intelligence committee. so that is kind of where the president is. so far it's not clear which way the white house is leaning. the president, though, on saturday, did sound off. he is reveling in the contrast of what's going to happen in the first impeachment hearing on wednesday. as democrats hold that hearing, the president will be abroad on international business. here's what the president tweeted on saturday. i will be representing our country in london at nato while the democrats are holding the most ridiculous impeachment hearings in history. read the transcripts. nothing was done or said wrong. the radical left is undercutting our country. hearings scheduled on same dates as nato. this is something quite familiar

we have seen from the president of course during special counsel robert mueller's investigation. the president repeatedly complained about the cloud that he had over his head as he went to meet with key u.s. allies abroad. he felt it undermined his diplomatic efforts abroad. and the president seems to be reprising that theme now that he faces the prospects of impeachment. jeremy diamond, traveling with the president, west palm beach, florida. joining me now via skype. thanks for doing so, professor. we have seen it in the intelligence committee. that's where the drama was. it is now judiciary committee. how different might that look and do you think the trump administration will take part? >> reporter: well, the house intelligence committee was sort of like a grand jury where you assembled the evidence. you had 17 witnesses behind closed doors, 12 in public. and then the house intelligence committee has to almost in

effect serve as a grand jury say is there enough weight of evidence here to proceed to the next stage. the house judiciary committee will probably not hear from a great deal of new witnesses on the evidence. they will talk to constitutional lawyers about whether these are impeachable offenses, whether it constitutes bribery. if the lawyers say yes, the judiciary committee will draft articles of impeachment. those articles of impeachment will be voted on. in effect, the house judiciary committee will be the procedural body in a says yes or no, is there enough evidence. if they say yes, there is bribery, obstruction of justice, they pass it to the "full house" for a vote before the christmas recess. . >> donald trump has been strangely quiet on twitter the last week or so. the twitter verse has been commenting on that. but he did tweet today. i think it was his only direct

tweet other than retweets. i will be representing our country in london at nato, while the democrats are holding the most ridiculous impeachment hearings in history. read the transcripts. nothing was done or said wrong. the radical left is undercutting our country. hearings schedule on the same dates as nato. is it undercutting the country holding these hearings? >> reporter: no. let's be very clear about what donald trump and perhaps his staff are doing this weekend, and that is the next phase of trying to block this inquiry. they first tried to block it by preventing any witnesses from showing up, telling current and former officials to defy subpoenas. that didn't work. 17 current and former officials testified, including his former ally, ambassador gordon sondland. you delegitimize the witnesses, saying they were disloyal to united states and ukraine. if you can't tear down the witnesses and can't say they are

illegitimate, you say, look, he is doing great things for the country, great things everywhere and you're stopping him from doing a great job. the fact of the matter is the biggest problem for donald trump in getting legislation getting legislation passed is donald trump. the biggest problem for nato isn't impeachment hearings, it is donald trump is unpredictable and insults foreign leaders. time to keep your eye on the ball and not get dust thrown in your eye. >> donald trump, as we said, he is going to nato. not going to be many friends to greet him. one of the allies, boris johnson, warned trump, warned him to stay quiet on the upcoming general election much other nato leaders who resent his admonishments.

how do you see it going? do you see a disruptive trump again? >> reporter: i have a well-placed league here in the uk who calls him a huge hand grenade. he has turned his back on other leaders, insulted the germans, threatened to walk out of the alliance completely before u.s. officials walked that back. he is a disruption for nato. they have serious issues but they are about tactics, strategy, not just finance. especially with a forth right russian challenge in eastern europe and other areas. and donald trump gets in the way of discussing those issues. you have to sort of discuss around his back. beyond that, look, boris johnson's people are worried. donald trump, three weeks ago, nearly sabotaged the prime minister's campaign by saying that he wants a no-deal brexit. in other words, he wants the uk to crash out of the european union. and boris johnson is saying vote

for me. will he cause his former ally more problems? we'll wait and see. . >> you have the role of turkey as a nato member, yet buying air defense systems from russia and a nato critic. joint patrols in northern syria. a couple of days ago you had mr. erdogan telling the french president to check, quote, whether he is brain dead. that was after mr. macron said he was on life support. i imagine a fairly awkward atmosphere with turkey. >> reporter: president erdogan is fairly craft politician. i don't think it will be his interest to tear up the nato summit. the big problem is a space was opened up really by the failure of u.s. policy on syria.

not just during the trump administration, that indecision, uncertainty, in ability to protect civilians led to turkey and russia to intervene. that is a bigger problem for nato and goes beyond donald trump and knoll the immediately be resolved at this summit. >> good point. university of birmingham. thank you so much. >> reporter: thank you, michael. all right. a plane crash in the u.s. left nine dead, including the pilot and two children. this happened near chamberlain, south dakota shortly after takeoff. three people survived and have been taken to hospital. officials say the crash was weather related. it happened during heavy snowfall, had reduced approximate visibility. speaking of which, a powerful storm affecting many trampers across the u.s. 50 million people coast to coast brace under rain, wind and snow.

hundreds of flights have been canceled. the storm moving east. what's in its path? meteorologist eric van dam joining us. >> we are getting thunderstorms from the same system. it is warm enough here to not cause a big deal. the east coast it will be a big deal. laguardia to jfk, boston international, dulles, they will have major traffic delays or airport delays, i should say. let's take you to south dakota. we talked about the plane crash that took place that now officials are calling as weather related. but you can see why, right? this is blizzard conditions. they have been dealing with in rapid city. some of the authorities tweeted out earlier on the day on saturday that there was a no travel advisory for the city. and that's as winds and strong bands of snow continue to wallop the area. this is a storm system. here's a look at the airport

delays. d.c. to philly, jfk, boston, we expect significant airport delays through the day today. this storm area is expansive from the central u.s. to the east coast. i will highlight the east coast. we know where the storm is headed. it is knocking on the doorstep of new york city and philadelphia. you can see the rain/snow mix with the shading of purple. we have the potential for a full-fledged ice storm up to a half an inch of ice across central pennsylvania. here's the 50 million americans impacted stretching from the new england coastline through the midwest and northern plains. still even blizzard warnings for some locations with the strong winds. this is a complex storm. we will try to break it down for you. the wintry mix will start this morning. there is enough warm air where it will transition to all rain. keeping snowfall totals down for

new york, philadelphia, and more so into the boston region. but on the backside of this, another secondary low will hug the coastline, draw in cold air, and transition it pack to snow. so we will still get snow for many of the upstate regions of vermont, massachusetts, connecticut, rhode island. boston proper, you have the potential for experiencing 6 to 9 inches of snowfall. i think it will be a slushy 1 to 2, maybe 3 in new york city proper. here's a look at what's happening on the other side of the world. this is the western pacific. i have to highlight this because this is a top story here for us at the weather center. 120 opinion her hour kilometers. the next 24 hours will be rough for the capital of manila with the potential of category 3 atlantic hurricane equivalent making listened fall across this vulnerable coastline. wind gusts sunday even local time across the philippines at

the moment. this storm system expected to make landfall late monday, early morning hours of tuesday. that means heavy rainfall and the poe toepl for landslides across this region. we can't harp enough on ow vulnerable this coastline is. >> derrick, good to see you. derek van dam. we will take a short break. iraq's prime minister has agreed to resign, but that has not stopped the unrest on the streets. why many iraqis say they will continue to demonstrate. plus, u.s. democratic candidate joe biden is on the move in iowa as he looks to move up in the polls. a look at where he stands ahead of the iowa caucuses. and when they were done, chevy earned more j.d. power quality awards across

and welcome back to our viewers in the united states and all around the world. you're watching cnn "newsroom". i'm michael holmes. we have the headlines now. one of the victims stabbed near london bridge is 25-year-old jack merritt who worked this a program to rehabilitate criminals. the justice memory is reviewing the parole of 70 other convicted terrorists also released from uk prisons. poland, meanwhile, celebrating the onlookers who took down the london attacker. a polish chief working in london

jabbed at him with a narwahl tusk. he said your attitude deserves a special thank you and respect. poland is proud of you. millions of holiday travelers in the u.s. will be met with rain, snow, or a messy mix of both in the coming days. 50 million people on winter weather alerts. airlines helping to help passengers change travel planes. hundreds of flights canceled. more than 10,000 delayed. iraq's council of ministers reviewed the prime minister's resignation offer after he vowed to step down amid protests. his exit requirements parliament approval. a vote is expected in the coming hours. he told the counsel that his government hasn't spared any efforts in responding to protester demands. the prime minister now calling

for a peaceful transfer of power. >> translator: we had taken brave and daring decisions at that time to prevent the use of live bullets. regrettably, when clashes happen, multiple complications occurred. this led to the fall of victims and negative consequences. so it is left to the government to adopt a polled stance in this regard and therefore a resignation is required in order to calm matters down. . >> it did not stop iraqis from returning to the streets on saturday. over the past two months, hundreds have died. arwa damon reports from baghdad. >> reporter: it's quite chaotic here, but this is shaymar. she was saying she just wanted the united nations to come in

and get involved and look at what is going on here, to come in and actually support the population. and they also want to end iran's influence. if you come this way, you can see what has become the defacto front line. and what they are trying to do here is keep pushing forward to take control of these vital bridges across the river. by to go that, they are hoping to keep up even more pressure on the iraqi government. because, they say, unless they keep going like this, unless they keep trying to push forward and make sure that their demands are heard, they say nothing is going to change. she is showing us what is being shot at them. they say this is the blood --

they say this is blood from someone who he says was just shot, who was just injured. and he carried him. and this is the blood. you can see really how intense it is here right now. again, as we were saying, these are demonstrators who are determined to hold this ground, to hold all ground that they have and to keep pushing forward pause, as i was saying, they want to make sure this time their demands are heard. and what they will also tell you is just demonstrating has not been enough in the past. they say they have to keep the pressure up. otherwise, they say the government will just keep on making empty promises. arwa damon, cnn, baghdad. turning our attention to syria in the aftermath of turkey launching that offensive into

the north of the country. it was nearly two months ago that u.s. troops were ordered by donald trump to pull back. and that left washington's kurdish allies at the mercy of turkish troops and their proxies. and they feel be strayed. clarissa ward has more on the civilians paying the price from the u.s. exit. >> reporter: class should be in session now. here the school has become a temporary shelter for displaced people. in one classroom, we meet ibrahim hassan, the kurdish father of five tells us he was forced to flee his home with his children when the turkish military operation began. this is what remains of his house. ibrahim says it is one of many in his kurdish neighborhood that was deliberately ransacked by turkish-backed forces. >> translator: they took

everything. and after they took all our belongings, they said set it on fired and burned it all. >> reporter: days before the offensive began, his children were smiling with u.s. troops. he said their presence gave a false sense of security. then suddenly they were gone. >> translator: since america betrayed us, every time i look at these photos of my children with the americans incident to erase them. >> reporter: do you trust the americans? definitely not. stkpwhrot now we hear and see on television that america is saying they are only here for the oil. why did trump do this? you have betrayed all the people. >> reporter: it's a sentiment we found shared by many here. 200,000 have been displaced by turkey's offensive. hundreds of their homes have

been damaged or looted. local authorities are now trying to move them out of the schools so that class can start again. and into haste live-built camps like this one. resources are scarce. pause of the security situation, international aid agencies have had to pull out. even occurreds with no one to rely on themselves. she's saying it's really difficult here pause it's very cold, especially at night. they to the floor enough food. they don't have electricity. and the water is not good. camp organizers say there are 3,000 people living here now, with more arriving every day. almost everyone in this camp is from a town that used to be around 75% kurdish.

now we are told there are just a handful of kurds left. and the people here believe the ultimate goal of this turkish offensive is to push the kurds out of this area completely some change the ethnic makeup of it forever. turkey has done little to alleviate their fears. as the kurds poured out of these areas, arabs have been passed in. syrian refugees who turkish authorities claim are originally from these areas. after more than eight years of civil war, this part of syria is full of stories of people forcibly displaced. in the christian village we found more families sheltering in the ruins of a destroyed church. will you try to go home, i asked the women? there's no home to go home to, they replied.

isis cleansed this area of christians when it was in control. they have yet to return. now the village provides refuge for another people, forced from their homes with no sense of a possible return. clarissa ward, cnn, northern syria. we'll take a short break now. when we come back, u.s. presidential candidate joe biden on the move this weekend. looking to regain momentum as he makes his way through iowa. why he is calling it a no malarkey tour. - do you have a box of video tapes, film reels, or photos,

welcome back. former u.s. vice president joe biden looking for votes in iowa ahead of the long awaited caucuses in february. and the presidential candidate has come up with a slow ggan me

to how how he is the real teal. >> reporter: joe biden kicked off what he calls his no malarkey bus tour. it will take him to 18 counties in iowa as he tries to meet one on one with voters. now, joe biden right now is leading nationally. he's the front-runner in most polls. but here in iowa, it is a eubgs somed race. pete buttigieg was shown as leader in the state with request joe biden battling it out for second. i asked about what this bus tour means. is this bus tour going to turn things around? >> i think our campaign is going fine. and i think it's going to help. we have to earn the votes. we have to show up. that's what i'm doing. . >> are can you win the nomination without winning in iowa? . >> yes. but i'm going to win iowa. . >> what are you telling voters

about why you want to win iowa? >> you got an hour? >> reporter: it is trying to put biden in front of as many voters as possible. his ability to connect with people is one of his key strengths ahead of the iowa caucus. as for why it is called the no malarkey bus tour, he said it's because the other guy, referring to president trump, is all lies. three charities have come up with a unique way to fight the stigma of hiv. they have set up the first hiv pofplt sperm bank. more about the initiative in new zeala zealand. sitive sperm bank. more about the initiative in new zealand.

today is world aids day. people around the world are wearing red ribbons. to mark the event, new zealand opened the world's first hiv positive sperm bank in the hopes of destigmatizing. they all have the virus. since the levels in their blood are so low because of new drug

treatments, they cannot submit through child birth or unprotected sex. joining me now, national coordinator at worst, two groups behind the initiative. good to see you both. jane, let's start with you. this is obviously good news for those with hiv. explain why someone would go to a sperm bank with hiv positive donors rather than donors without the virus. >> i guess there is a two-year waiting list in regular fertility clinics. so it's not always that easy. we are doing it from the perspective of people living with hiv who over the years have not had the opportunity to be parents. and so -- and we really want to highlight the fact that now with the changes in hiv medication where people can now have an

undetectable viral load and not pass on hiv, it is okay to be able to donate sperm and not pass hiv onto the partner or the children. . >> right. a major aim is raising awareness, haoeuf is far from a death sentence these days. it's not. and also reduce discrimination with that knowledge. how much of stigma remains even with medical advances and what does that stigma lead to? . >> there is a huge amount of stigma existing. just from putting this campaign out there, the amount of negativity we've got towards it is quite significant. people aren't convinced they

have zero risk in that process. it's been a long journey. >> jane, you mentioned this. let's talk a little bit about it. the advances made with hiv. other people probably don't know. as i said, it's no longer a death sentence. it is a manageable condition now, isn't it? >> absolutely. i myself have been living with hiv for 32 years. and that's all down to the medication. what happens nowadays, as soon as someone is diagnosed with hiv, they will get onto medications. within three weeks to three months, the virus will be undetectable, which means it will be undetected in the pwhraofpltd it doesn't mean you no longer have hiv. it is dormant. it cannot be passed on to a child. it is more of a chronic life

illness. you still have to take medications every day. but our life expectancy is the same as someone who has not got hiv. >> do you have any donors yet and any clients? what's been the reception. . >> we actually have had seven donors come forward and seven women recipients who would like to. yeah, it's been very successful. . >> women with or without hiv? >> without hiv. >> that's a big deal. . >> yeah. >> seven men without and seven women without. ironically, it is seven and seven. funny after three takes of the campaign going out. so there is -- while there's been a lot of negativity which highlights the need for the campaigns, there's also been a lot of positivity.

it shows there was a need for this. . >> you know, when we were talking about this here in the "newsroom", several people were like this is great but if you were not hiv positive, why would you two and even if there is no risk, in your head you might be taking a risk. why would you do that? just to hear there's seven women hiv free who signed up for this is remarkable, isn't it? what's your reaction, mark? . >> i think it's amazing. it shows people have learned there is no risk. it is all about creating life. that's what we are to go this for, is to give people living with hiv to do that altruistic piece of being able to share and help someone have a child. it is hard to get clinic donations in terms of sperm donors.

>> we will work with these companies and work with the fertility clinics and match them up. we will work through it the next few weeks, months. . >> and the other thing is we want to change the what wii fertility clinics work around the world so they can take on people and support them living with hiv because there is no work. >> we have to leave it there. but that's remarkable. it's just so encouraging that you have hiv-free women coming in and saying yes because there is no risk. great news. good luck with it. . >> thank you very much. thanks. pi. >> extraordinary stuff. in news. thanks for watching cnn

"newsroom". i'm michael holmes. i'll be back with more after the break.

today is the deadline for the white house to decide if they are going to a participate in the impeachment inquiry. will they deflect or defend? you may have heard about the heroes who rushed the london knife attacker. we have footage of that. you won't want to miss it. the president of brazil said this movie star is to plame. hear his
