amess today. live in london with the details. plus, the latest on china's economic struggles. we'll break down the disappointing gdp numbers from a live report from hong kong. live from cnn center, this is "cnn newsroom" with rosemary church. good to have you with us. well, a security source in haiti now tells cnn one of the country's most powerful gangs is believed to be behind the brazen kidnapping of a group of missionaries. 16 americans and one canadian were abducted on saturday after visiting an orphanage east of port-au-prince. the christian aid ministry says five children were among the group. the haitian security source says the gang called 400 moroso has been growing in strength and has been fueling the recent surge of kidnappings. we are following this story. good to see you, melissa. what is the latest on this kidnapping and the gang that authorities say is behind it? >> reporter: that gang, 400 mawozo, one that controls the gangs north of port-au-prince. it has specialized in car theft, expanded its activities and had become one of the big fuelers of this real surge we've seen in kidnappings. of course this case as we wait for news of the fate of the 17 missionaries that were kidnapped including some of their children will continue to attract attention. for ordinary haitians going about their life, this is really the scourge that is troubling people in the haitian capitol. to give you an idea of the figures, 629 kidnappings since january, 29 foreigners. just since july according to an ngo, there's 300% rise. parents will hold their children ace hands, whether they're 16, 17, 18. >> just a terrifying situation. what's the latest you're learning on the protests against kidnappings? >> reporter: that's right. there has been a growing anger and a series of strikes and protests because all of those very high profile and growing number of cases of people being kidnapped in broad daylight most of the time and then being held for ransom. people will be out on the street of port-au-prince making their displeasure known. the resigning u.s. envoy had mentioned in his letter when the biden administration was returning that he was standing down on the grounds of the american policy but also on the fact that there had been too much support for political classes working with gangs and that gives you an idea of the level of insecurity in a country that has only grown since the assassination of the president back in july, rosemary. >> melissa bell bringing us you up to date on all of those issues. one house republican weighed in on what the u.s. should do to help rescue them. >> we need to track down where they are and see if, you know, negotiations without paying ransom are possible or do whatever we need to on a military front or police front. yeah, i mean, i think probably everybody watching, at least one or two i guess kevin bacons away knows somebody that has been a missionary to haiti at some point. this hits home. we keep them in our prayers and the u.s. government will do everything kwee to get them back. >> cnn's kiley atwood has more. >> reporter: confirming 16 americans and one canadian, 17 in total missionaries in total abducted by a gang over the weekend. they were there working at an orph orphanage. they were leaving heading north. the u.s. government doesn't know the current location of those americans who have been kidnapped. they are working around the clock. state department officials, fbi officials to try to figure out how they were aware of the reports and wait willing to see if the white house comments in on it. they suggest all-americans don't travel to haiti, particularly because of these kidnappings. the travel advisory cites kidnappings. kidnappings in haiti have been on the rise in the last few months. since july they have risen 300%. that doesn't include this latest development over the weekend with these 16 americans kidnapped. kiley atwood, cnn, the state department. the extradition of a columbian businessman is fueling the latest standoff. alex saab is due in a florida court today as he faces charges of money laundering. maduro supporters are protecting against it. cnn's raphael roma has more on the fate of the sit go 6. >> reporter: a group was imprisoned after maduro was extradited. many think it was a retalleyation move. the group known as the citgo 6. they were arrested in 2017 in caracas on embezzlement charges which they deny. two told us they are being held in caracas. this is where one of them died due to covid-19. 20 inmates have tested positive for covid-19. a family member posted he was recorded about being taken to prison. many in the venezuela opposition say this is nothing more than a retalleyation move. saab is going to appear in court on monday. why is the venezuela government protesting his extradition? because it means that one of president maduro's closest confidantes may be available for interrogation, someone who knows the ins and outs of a totalitarian regime. members of parliament will pay tribute to british mp david amess in the house of commons in the coming hours. they are also set to discuss how to prevent another tragedy like this again. the suspect was arrested at the scene. a government source says he is a 25-year-old national. what more are you learning about the tragic murder of david amess and what action might be taken. >> reporter: two big questions now here in the united kingdom, in brittain. it's something that's been widely discussed, especially among politicians here in this country on how they can be better protected. the investigation is also going on. you mentioned the person arrested was a 25-year-old u.k. citizen who is a somali. there is no further threat from this gentleman or any other ring in the wider public. the investigation is ongoing also forced to decide what the possible motives were. one of them that has been put out there is possible islamist extremism. there are many nuances to that that the investigators are trying to find out. at the same time we do have the discussion going on about how better to protect members of parliament and members of congress. this is the second murder of a member of parliament just in the past five years. >> the problem is they visit people and how will they consider whether or not it is secure enough to be asked. one of the big questions, can you a ford to continue these meetings? do you need tighter security measures? one of the things we've heard is from the speaker of commons. he doesn't want any knee jerk election. they tonight want you to be there for the public and interact. there are things that need to be discussed. all of the members of parliament will see calls to see if they sneed the security. in the end what's being discussed right now is this needs to be decided on a kase by kase basis. >> that will be a delicate balancing act. fred pleitgen bringing us the update. many thanks. >> the taiwan strait remains a flash point between the u.s. and china. this time canada is getting involved. beijing is furious after reports the u.s. and canada sent a warship into the strait. it threatens peace and security. the latest round of gunboat diplomacy comes after china's own shown of force. meantime, china's economy grew only 4.9% in the third quarter, its weakest expansion in a year. the country has been able to rebound from pandemic difficulties but seems to be losing steam amid a multitude of problems including supply chain issues, covid outbreaks and energy shortages. cnn's christi lu stout joins us live. what is behind china's weakest rate of expansion in a year? what impact could this have on the region and the world? >> reporter: global economic growth is slowing down. that's what we learned when it revised down the global economic forecast. earlier today china announced they had grown 4.5% growth china had reported. china is con stronting an array of items. the energy crisis is caused by the record high price of coal. that has led to power outages and forced china to rags electricity in 20 prove vipss. it's forced factories to suspend production which has led to a false output. and they're the company with over $300,000 priorities. there are fears chd the gdp. even before today's third quarter gdp. they had lr vietszed downward. take a listen to this. >> the data suggest there are multipling items facing the chinese economy. some are temporary, some can be long lasting. the key long-term challenge here is the housing market crackdown. >> now we heard earlier today from the spokesman of china's national statistical bureau and he insists the property marmt will hold both. christi lu stout joining us. the pt government is gaining ground. why they say it's just not enough. h. >> president trump refuses to comply with a federal subpoena. the charges he could face. feel the power. beat the symptoms fast. your mission: stand up to moderate to severe rheumatoid arthritis. and take. it. on... with rinvoq. rinvoq a once-daily pill can dramatically improve symptoms... rinvoq helps tame pain, stiffness, swelling. and for some, rinvoq can even significantly reduce ra fatigue. that's rinvoq relief. with ra, your overactive immune system attacks your joints. rinvoq regulates it to help stop the attack. rinvoq can lower your ability to fight infections, including tuberculosis. serious infections and blood clots, sometimes fatal, have occurred as have certain cancers, including lymphoma, and tears in the stomach or intestines, and changes in lab results. your doctor should monitor your bloodwork. tell your doctor about any infections... and if you are or may become pregnant while taking rinvoq. take on ra. talk to your rheumatologist about rinvoq relief. rinvoq. make it your mission. learn how abbvie could help you save on rinvoq. former u.s. president bill clinton is recovering at home. he was treated for sepsis after a urinary tract infection spread to his bloodstream. clinton left the hospital sunday morning along with his wife, former secretary of state hillary clinton. he gave a thumbs up when asked how he was feeling. the u.s. is gaining ground in the fight against covid-19. the rate of cases is improving. fewer patients in hospitals. debts down compared to a month ago. the cdc says 57% of americans are now fully vaccinated. winter is coming which means more people gathering indoors and dr. anthony if you chi says we could see another surge if more people don't get vaccinated. >> we're going in the right direction, the problem is, as we all know, we still have approximately 66 million people who are eligible to be vaccinated who are not vaccinated. the degree to which we continue to come down in that slope will depend on how well we do about getting more people vaccinated. >> joining me is dr. jorge rodriguez. thank you for all that you do. >> thank you, rosemary. glad to be here. >> according to cdc data, 57% of the u.s. population is fully vaccinated against covid-19 which is nearly 67% of eligible unions. as bejust heard from dr. fauci, 66 million americans, how do we encourage more people to get their shots? do we need to learn to live there with could he individual? >> i know dr. anthony pow chi and everything is it not a good reason. things are better but we still have 85,000 cases a day. if this starts ramping up when we are at this high level we are in deep trouble for the winter. 57% or whatever it is total vaccination, that's an f. there are other countries that are 100%. portugal, for example. australia opened up a few months ago and they're at 80%. we can do better. we must do better. are we goings to have to learn to live with covid? to some degree. i think everybody that is in science is in agreement that this is going to become an endemic infection, meaning it is not going to be all over the world eventually but we are going to flair you were. it's like anti up? >> i don't know why folks are concerned about getting that shot. what's your reaction to the booster after a second month. >> my first reaction is studies are showing 6 or 7 months after the people that have gotten the j&j vaccine, their protection may be down to 3%, maybe in the single digits. people are saying those vaccines don't work. the correct response is, wow, look how great science is that they're able to get us this information so quickly so that we can do something about it. so, yes, the recommendation by the fda panel is anyone who has had a booster. >> doctor, an nih study shows that mixing and matching booster shots could be effective so would it make better sense, perhaps, for recipients of the first j&j shot to get a moderna and pfizer instead of the j&j option? >> the final verdict on that is still out. i know a lot of people have gotten it and have not followed the recommendation. when we know more you may have a recommendation you can mix and match. again, it is incredible we are getting this information in real time. right now if the fda approves it. >> if the cdc approves it. they should get their j&j booster very soon. >> we know 65 and above have been receiving their booster shots. dr. fauci said that there is promising evidence from israel that those between the age benefit from getting a boothser shot of moderna or pfizer. do you agree with that? >> i do wholeheartedly. people even younger than that should get the booster. at first not all people at the outset even though people have gotten the vaccine, it doesn't matter your age, there is a surplus of vaccinations. some of our countries are very lucky to have that. then the booster should be given to anyone and it's the time span that should be the determinant if there is a surplus and enough to go around. >> always great to talk with you. many thanks. new zealand is extending lockdown measures for two weeks in aukland. the country's largest city. the prime minister made the announcement just hours ago. aukland has been in lockdown since august due to a spike in delta variant cases. this comes after new zealand's government says it set new records with its super saturday vaccination drive. officials say 65% is fully vaccinated up 3%. steve bannon is refusing to talk to congress. coming up, while donald trump's former strategist ignores a subpoena, lawmakers investigating the january 6th insurrection consider their next move. and gabby petito's hometown community turned out for a huge fund-raiser in her memory. again, how the event could help so many people. it's another day. and anything could happen. it could be the day you welcome 1,200 guests and all their devices. or it could be the day there's a cyberthreat. only comcast business' secure network solutions give you the power of sd-wan and advanced security integrated on our activecore platform so you can control your network from anywhere, anytime. it's network management redefined. every day in business is a big day. we'll keep you ready for what's next. comcast business powering possibilities. a 2015 protest against donald trump's immigration rhetoric is forcing the former president to give sworn testimony in the coming hours. a lawsuit accuses trump's former head of security of assaulting protestors outside trump tower. their lawyer wants to determine whether trump is responsible for his employees' behavior. >> reporter: for the first time before leaving office former president donald trump will testify under oath. on monday trump will sit for a videotaped deposition in a case stemming from a 2015 lawsuit. he and his company were sued. last week a new york state judge said his testimony was indispensable. they will question about any orders. the lawyer could ask trump about matthew kala march ri, his top official overseeing this. trump has previously denied any knowledge of the alleged incident and said he delegated full responsibility of security to calamari. monday's deposition will be played before a jury when it goes to trial. he's facing a late december deadline for another case. tara skinell, cnn, new york. the man behind the controversial trump russia dossier is speaking out for the first time since the document was released. christopher steele broke his silence about the dossier in a new abc documentary. it included 35 pages of intelligence memos that painted a picture of collusion. he's standing by one of the most salacious claims in the unverified dossier that russia has a compromising video of trump in a hotel room surrounded by prostitutes. >> do you think that tape still exists? >> i think it probably does but i wouldn't put 100% uncertainty. >> how do you explain that? >> i think the russians felt they got pretty good value out of donald trump when he was president of the u.s. top officials presented them with claims from the steele dossier. there is no evidence the tape exists and trump has denied the alleged incident. the house committee investigating the january 6th insurrection has issued a number of subpoenas to allies of former president donald trump. some committee members are not ruling out the possibility of subpoenaing trump himself. >> if we subpoena the former president, we know that's going to become a circus. that's not something necessarily we want to do up front. if he has pieces of information we need, we certainly will. the trump loyalist is refusing to comply with a subpoena. we have the report. >> reporter: while the investigation into january 6th is poised to take a pivotal step forward, the select community will report on steve bannon who's refuse to go comply. he's a former trump adviser. he had the president's that all hell was going to break loose. the committee has a full ends in the feature. it only refers to us whether we hold bannon in contempt. we night not see a resolution on this for quite some time. nonetheless, the committee is pushing ahead moving quickly and aggressively. all this this comes as they consider whether to subpoena trump. joining me from at lan two. great to have you with us. >> the january 6th committee will hold him in critical supply because he's unwilling to talk to when he say the a hit violence that day. despite being fired by president trump up to the 24th what will happen. >> my view is that steve bannon as a member when all of these conversations took mace. in heft in 2017. had the court said can't claim executive privilege. add to that the fact that he really is trying to piggyback the former president trump's claim of executive privilege. we have already seen. the biden white house in a very specific letter, i'm paraphrasing here said, look, you don't get to try and subvert the constitution and then wlap yourself in the constitution. not specifically written in the. if you want free and unfettered interest. we'll balance that against the public's right to know. there was an insurrection, there was an attempted coup and the public deserves what happened? >> now sheerly would have to give hifs roll. >> it's hard to believe you could piece this together and not call together frumpd. we know having seen the first impeachment and subpoenas, you can win even if you have a losing legal aural content. a lot of that information is publically available. parts we all deserve to hear. our country, our constitution under risk and our government under siege. if former president donald trump drags this out in congress and then in the courts, this is a problem if you are the house democrats and you've said i want to wrap up our work by early spring. it's the same reason steve bannon could win even though he has the clock here. well, it's been about one month since gabby petito's remains were found in wyoming. investigators are still searching for her monday. as her family struggles with heart break, they're turn this away in a way to help others. >> reporter: this was the first benefit for the gabby petito foundation. the foundation is going to be designated to finding missing people, helping those not in the healthiest of relationships. this is the community where gabby petito was from. these people know her family. they knew gabby. someone i spoke to at today's benefit said that gabby was a very kind person, that she always wanted to see the best in benefit. they also had their individual reasons for being here. >> i don't know gabby. she was a young, beautiful girl. they had her whole life ahead of her. i wanted to come and support the foundation and hope something positive will come. >> you think of your own children. what happened to gabby was such a terrible thing. for the foundation. >> gabby petito means everything to this community. she loved this community, was an active participant in this community, as is the family. we dedicate this eye know. we hope you ever happy. >> this say criminal investigation. brian laundrie has not been charged with anything relating to gabby petito's disappearance. her father tweeted out at the end something from the grand tetons. i now know why you came here. it has a beautiful memory from now on. 5/7. brian laundrie's family went to law enforcement saying our son is missing and we cannot find him. jean casarez, cnn, new york. in the coming hours jury selection is set to begin in the trial of three men accuse of killing ahmet ar bury. he was joking in february of last year when thuf to this a. they dlu r include -- days of rain have led to deadly flooding and landslides in southern india. a live update from new delhi is next. ♪ ♪ ♪ ♪ ♪ ♪ with chase security features, guidance and convenience, banking feels good. chase. make more of what's yours. we've seen quite a few landslides into the area and flash floods taking place. this could be perhaps because of more organization and construction in the area. officials have told cnn is that about 6500 people have been evacuated from different areas. we do know that over 180 relief camps have also been set up and forces have been deployed. you have military choppers pulling people out. you have rafts and boats taking people to safer homes and they have been mostly submerged. towns and villages being cut off. prime minister mode did i has spoken with the prime minister. we are being told the rains have stopped as we speak for the day but the biggest challenge that the state could face currently is high waves that are expected for tonight. that's the biggest challenge they're up against in the coming hours. >> thank you so much for staying on top of this story. we appreciate it and we'll be right back. start your day with crest 3d white and from mochaccinos to merlot, your smile will always be brilliant. crest 3d white brilliance. 100% stain removal, 24 hour stain resistance to lock in your whitest smile. crest. the #1 toothpaste brand in america. hi sabrina! hi jen! hi. so you're the scientist here. i just have to ask. does my aveeno® daily moisturizer really make my dry skin healthier in one day?
